How Foods Fight Cancer

While there are a lot of technical terms to explain how foods help fight cancer, the simple and easiest explanation to understand is simply, that certain foods contain vitamins, minerals and nutrients necessary to strengthening your immune system which aids in fighting a variety of diseases including cancer. Other foods have specific nutrients that help block or attack free radicals that cause cancer and some foods are believed to actual deactivate carcinogens and suppress cancer growth.

Think Green

Including a lot of green vegetables in your diet will help fight cancer. Green leafy vegetables such as cabbage, spinach and kale, all contain vitamins and minerals that will enhance your bodies immune system and fight cancer. Chili and Jalapeno peppers will also aid in your fight against cancer by preventing the activation of cancer causing chemicals.

Broccoli is one of the best cancer foods available today. It has a number of vitamins and nutrients that will deactivate carcinogens and are believed to aid in suppressing the growth of cancer cells in the body.

Red and Orange Vegetables

Red and orange vegetables such as carrots, tomatoes, and sweet potatoes all contain antioxidants as well as a variety of other vitamins that will strengthen your immune system. Eating one or two servings of these colorful vegetables along with green vegetables daily will help you to build an immune system that is strong in cancer fighting vitamins and minerals.

Fruits

Citrus fruits such as oranges, lemons and limes all contain high doses of anti oxidants. These fruits actually stimulate cancer killing immune cells. Figs, red grapes, papayas, raspberries, strawberries, and apples can help to neutralize cancer causing chemicals.

Herbs and Spices

There is a variety of herbs and spices that can help fight cancer. Turmeric and Ginger are two spices that fight cancer by actually tricking the cancer cells into attacking one another rather than attacking healthy cells. Garlic interferes with the cancer causing enzymes.

There are many other foods that help fight cancer and strengthen your immune system. Nuts, green and black tea, soy, onions, the list goes on and on. For those wishing to partake in a diet of cancer fighting foods the best approach is to follow the food pyramid. By making sure that the vegetable portions contain a lot of green, red and orange vegetables we can further help our bodies defend against cancer cell growth.

Just as we can eat our way to poor health, we can also eat our way to good health. Choosing those foods that are high in anti oxidants, beta-carotene and all the vitamins and minerals necessary to build a strong immune system and activate our body’s ability to fight cancer.

Prostate cancer symptoms range from lower back pain, blood in your urine, difficulty starting urination, pain during urination and the frequent need to urinate. These types of symptoms do not always mean that you have prostate cancer and most of these symptoms can be attributed to something else. That is why it is vital for all members of the male population over 50 to get a prostate exam each year.

How Proper Nutrition Can Help Fight This Disease

Eating the right foods, getting the right vitamins and minerals will go a long way towards building your immune system and helping to prevent prostate cancer. The first thing you want to try and reduce is saturated fat and then you want to increase the amount of fiber that is in your daily diet. Research has shown that prostate cancer cases are higher in the more advanced countries where higher saturated fat levels are found in the normal daily diets. To back up this research studies have shown an increase in the cases of prostate cancer as third world countries begin to adopt a more western diet, a diet that contains a higher level of saturated fats.

If you are interested in changing your diet to one that will have the advantages of preventing prostate cancer then you need to know that beef and pork, and red meat are thought to increase the risks of getting cancer of the prostate. These meats contain a very high level of saturated fats and dairy products also contain elevated levels of saturated fat and have also been targeted as a contributor to cancer of the prostate.

A Healthier Lifestyle Starts With Cutting The Fat

One of the more effective ways to reduce your risk of getting prostate cancer is cutting back on the saturated fat that is in your daily food consumption. If you have a family history of prostate cancer then making dietary changes that will help fight off this dreaded disease are highly suggested. If you are experiencing any of the symptoms above go to see your doctor and get a check up. Usually one of the first things you will be told is to make the changes in your diet, doctors and nutritionists all agree that it helps.

Changing your diet will also have other benefits that come with it, a reduced risk of diabetes, it will be easier to control your weight, you will have more energy and you will have better overall physical fitness. So start to trim those saturated fats out of your diet, then add some fiber and start now. Increase the amounts of fruits and vegetables you consume as they are rich in nutrients, taste great, are low in fat content, high in fiber and should be a part of all healthy diets.

If you are thinking it is time to begin to eat healthier, exercise more and make your body become stronger to help fight prostate cancer. Then it is time to consult with your physician, nutritionist or other health professional and get the most out of your dietary changes. They will be able to advise you about what will work best and also lend a hand with monitoring your progress.

Prostate cancer is most likely to happen to men who are over 50. Of course, this cancer can only happen to men because women don’t have prostate glands. It is the second most common cancer for the American men following lung cancer. But studies show that men who are diagnosed with prostate cancer don’t die from it. Unlike most cancer, prostate cancer is slow in developing. Strangely enough most men with prostate cancer die of other causes.

As mentioned earlier, two symptoms of possible prostate cancer diagnosis is having pains while urinating and having difficulty in getting an erection. Sometimes, the symptoms are frequent urination, mostly at night. If diagnosed men do get an erection, ejaculation is painful.

Prostate cancer is determined from a physical examination. A possible inflicted person has to go through a blood test. X-rays and bone scans are also performed, just to check whether the cancer has already spread.

This is because advanced prostate cancer may lead to other symptoms like bone pain, pain in the pelvis and ribs. If not detected early on, prostate cancer may advanced and continue to have side effects on the spinal cord of the suspected patient, thus his legs weaken and even his way of walking will be affected.

Some hospitals conduct screening tests because this is their attempt to help out those who didn’t suspect they have prostate cancer. Unlike women, men don’t go to their urologists regularly. As of 2006, prostate cancer screening tests also include a prostate specific antigen blood test and digital rectal exam.

Stages of prostate cancer are the TNM system. These are a series of tests that show the results whether a T1, T2, T3 or T4 cancer are found in the prostate. Strength of the pelvic bones and random bone scans near the prostate are also conducted. They also check seminal vesticles.

The sample, which is the semen, is taken under a microscope to be examined by a pathologist. From there, he’d see how much tissue has already been damaged by the cancer. The Gleason system is the chart that indicates the abnormality in the prostate cancer effects, 10 being the most abnormal.

Treatment for prostate cancer is hormone therapy, radiation therapy or surgery. Often times, chemotherapy combined with the mention three can also help. Factors that affect the condition of a man with prostate cancer and the rate of how fast the virus can spread are his age and his octogene history. Case study of prostate cancer leads to a conclusion that is a disease for older men.

Causes of prostate cancer are also unknown, just like women who have ovarian cancers. Prostate cancer has a 50-50 chance of striking an individual, either you have it or not. If you do have prostate cancer, go to your nearest urologist. Unlike other cancers, prostate cancer when detected early on has a better chance to be cured.

In the United States, 42,000+ individuals are expected to be diagnosed with this condition in 2009.    

Symptoms are not specific and vary from one person to another. There’s also no telling what the specific cause is but there are risk factors for those who are possible to get it. Pancreatic cancer is also referred to as exocrine cancer.

Risk factors for pancreatic cancer are:

- Age, the older the higher the chances

- Mostly men, women are rarely diagnosed

- African-American, Caucasians are less likely to be diagnosed

- A carnivorous diet or mostly meat, vegans’ diet is not obliterated by the tumor

- Smoker

- Obese or Over Weight

- Diabetic

- Exposed to dyes and pesticides or chemicals that are associated to gasoline

- Ocnogene or family history of the ailment.

The common symptoms for pancreatic cancer are:

- Pain in the upper abdomen and/or upper back

- Loss of appetite

- Extreme weight loss

- Jaundice which causes dark urine, yellow eyes, and yellow skin

- Dilation of the gall bladder

- Nausea and vomiting

Take note that jaundice, although painless, takes place when the tumor has grown and its pressure becomes an obstruction to the bile duct. This causes abdominal pain to the affected person.

When the patient feels the mentioned symptoms, it is best that he go to a hospital and have a Physical Exam, lab test, CT Scan and an Ultrasonography performed.

Like ovarian cancer, treatment of pancreatic cancer depends on the stage the tumor is in.

Stages of Pancreatic Cancer:

- Local or Resectable Stage

Here, the disease is merely confined to the pancreas. It is separated from the blood vessels that are around the area.

Treatment is surgery. Other options are postoperative chemotherapy.

Based on previous cases, the survival time for those who are at this stage are 17 to 19 months.

- Locally Advanced or Unresectable Stage

At this stage, the cancer is encased or compressed the blood vessels that surround the pancreas.

Treatment is chemotherapy with or without radiation.

Those who are experiencing this stage of pancreatic cancer are predicted to survive for 8 to 9 months.

- Metastatic Stage

This is the worst stage of pancreatic cancer because the infection has already spread into the other organs such as the lungs and the liver.

Chemotherapy is the treatment: Survival for those at this stage are 4 to 6 months.

Notice that once a person has pancreatic cancer the chances for survival are not good. The time that a person can combat this cancer depends on the stage that the cancer is in, along with how effective the treatment can be.

Sometimes when the patient does survive the cancer, there’s also a chance that they go back because the cancer has returned yet again. Sad to think about it but once you have pancreatic cancer, it’s really hard to be cured from it.

That is why it is often advised to everyone to be very careful of what they eat. Too much oil in food is not good in anyone’s health. So is too much alcohol. Smoking is also a problem. People who take in too much oil and fat, smoke and drink a lot have a high risk of having pancreatic cancer.

In the U.S., skin cancer, being the most widespread type of all cancers, affects approximately 1 million Americans each year.

However, the great news is, today skin cancer is a curable condition when discovered early then promptly treated.

All skin cancer forms develop keeping similar patterns. Typically, the first indication of cancer is a change of you existing mole’s appearance, the development of a “new mole” on your skin or a specific area of your skin changes change appearance.     

Skin cancer may not become evident for several years and skin cancers rarely develops before an individual reaches the age of twenty or more.

Skin cancer types

1. Basal cell skin cancer. This typically appears to be a tiny lesion or wound in your skin lasting for up to three weeks or more. The lesion appears waxy, it is detected easily and can be treated successfully.

2. “Asquamous cell”. This cancer type generally starts as a tiny raised and small bump and at times can have a sore at the center. Usually, it does not feel itchy or even cause pain.

Typically it is found at the edge of the face, ears, mouth and lips but can also spread to other parts of your body. It is more insistent compared to “basal cell carcinoma”, but is extremely treatable.

3. Melanoma. This type is the most serious form skin cancer, it is formed from melanocytes which are normal cells in your skin which produces melanin.

Causes

For all skin cancer forms, sunlight exposure is the most significant environmental factor.

Research evidence reveal that sunburns when obtained in early childhood may bring about skin cancer during maturity.

Risk factors:

• Faired skinned and red or blonde-haired individuals.

• Those that have “light-colored” eyes.

• Those that are easily sunburned during sun exposure.

• Has a lot of freckles, moles or birthmarks.

• Excessive working or playing outside.

• Having had serious sunburn.

• Has family history “of skin cancer”.

• Tanning under the sun or tanning using a sunlamp.

Treatment

Depending on the type of skin cancer, a combination of new, innovative and traditional therapies are offered by doctors and determine the combination of suitable therapies that can include the following:

1. Surgery. Is often used as a treatment for skin cancer. There are several types of surgery depending on the stage and location of cancer.

“Mohs micrographic surgery” is a type of surgery method that although is very complex and necessitates special training, has the highest “cure rate” since the tumor is delineated microscopically until the growth is totally removed.

2. Radiation therapy. Is a treatment using “high-energy” rays to shrink or kill cancer cells.

3. Photodynamic therapy. This involves a two-stage procedure which is done usually on outpatient basis. Generally, a “light-activated” drug is injected that targets the cancerous cells.

Then after about 24 to 48 hours a “laser light” is then directed onto the tumor cells via a scope that exposes the cancerous cells unto a light spectrum that switches the drug on, killing cancerous cells but not damaging the healthy tissue surrounding it.

4. Topical chemotherapy. Simply, medication in the form of cream or ointment is directly placed onto your skin.

Prevention

• From 10:00 in the morning thru 3:00 in the after, which is the sun’s peak intensity, do wear sunglasses, woven clothes and hat or umbrella when you go out.

• Never use tanning booths and sun lamps.

• Every time you go out, even on cloudy days, always apply a sunscreen on with “sun-protection factor” of 15-30 hours.

• Every month, check your skin for skin cancer signs.

According to recent estimates, about 50 percent Americans who will live to up to age 65 or more years, will acquire skin cancer. So any lesions or bumps or abnormal skin growth you may have on your skin, never take it for granted. Just to be on the safe side, see your doctor at once.

As the malignant tumor continues to grow and develop, it then infiltrates the mucous layers and membrane as well as its surrounding tissues namely the neck, lymph nodes, lungs and other neighboring organs are affected gradually.    

Throat cancer occurs mostly in three regions namely the nasopharynx, the hypopharynx and the oropharynx.

Throat cancer actually occurs in men 3 times more than in women and does not develop usually before they reach 50 years old.

A study done by “The American Cancer Society” revealed that there are about 28,000 or more new oral cancer cases which includes the mouth, lips, tongue, salivary glands and gums that occurs yearly in the U.S.

Throat cancer affects that portion of your throat which is barely behind your mouth. About 7,000 or Americans die every year due to this form of cancer.

Causes

• Smoking.

• Excessive f alcohol consumption

• Inhaling asbestos, diesel fumes, coal

• Poor oral cleansing or hygiene

• Excessive eating of “salty meat”

• Abnormal growth of tissue

Symptoms

Early throat cancer indication is the change in the manner your mouth’s soft tissues will generally feel and look. Other symptoms include:

• Sore or sores in the mouth does not heal but increases its size.

• You will feel persistent mouth pains.

• Dark red or white patches and lumps can be seen and felt in your mouth.

• Thickening of the cheek.

• Difficulty in swallowing, moving the tongue or chewing.

• Difficulty moving the jaw, or there is pain and swelling in the jaw.

• There is soreness in your throat or that you feel that there something is blocking your throat.

• Your teeth are loosening and you experience pain around the teeth area.

• You feel that your tongue is numb.

• Voice change.

• A lump inside your neck.

• Severe ear pain but with normal eardrums.

Prevention

You must stop or avoid or minimize smoking and quit consuming alcoholic drinks, because they can irritate the throat. You may want to begin with a daily dose of herbal tea, do some research and come up with the best blend for you.

Treatment

Throat cancer is very complex and risky. Factors that are usually considered by physicians are the stage of cancer development, location of cancer growth and the impact the treatment could have on the patient’s speech.

If detected at its early stage, throat cancer can be successfully cured through surgery and radiation.

However, if caught on its late stages, extensive surgery will be needed and the pharynx and larynx will be removed.

Pharynx removal demand surgical tube insertion to let the food pass. When cancer experts successfully remove the larynx, the patient will need to learn again how to talk. Half of total cases however, remission is successfully obtained.

Unfortunately, in many cases throat cancers usually are already far advanced when people affected by it are aware of the symptoms and when the doctor makes a diagnosis of the growth.

The reason behind is that throat cancers cancer are generally painless up until in their advanced stages.

Regular self-examination or mouth evaluation and assessment and being sensitive to what you feel in your mouth and throat is the easiest way so to discover the disease at its early stage, because when discovered early, throat cancer is very treatable.

The most common oral cancer is the sqaumous cell carcinoma which begins in the tissue located in the line of the mouth and the lips. This is because oral cancer often revolves around the tissue of the tongue or the lips.

Oral cancer may also take place on the floor of the mouth, gums and cheek lining. Sometimes, it can also be located at the palate or the roof of one’s mouth. Squamous cell carcinoma are malignant and have the tendency to spread quickly.

The cause of mouth cancer is still being researched on. There are lot of possibilities how one can incur the disease. One of which is if he has the history. Like lung cancer, oncogenes are activated when DNA mutates.

Like lung cancer, smoking especially tobacco smoking, can also lead to mouth cancer. To elaborate more, heat from cigars, cigarettes and tobacco pipes can irritate the mouth’s mucous membrane. Chewing tobacco can also create irritation on the oral membrane, and recent studies have given more credit to chewing tobacco and snuff to causing mouth cancer in prolonged users.

If smoking is not enough, alcohol is also an activity associated to mouth cancer. A person is at a high risk to have oral cancer if he drinks and smokes heavily. Their risk is double than a heavy smoker or a heavy drinker.

If one is wearing dentures or fillings, one must always consult his dentist because if these aren’t cared for, then luekoplakia can occur. Luukoplakia is an infection in the mouth due to dirt seeped into the gums from fillings or dentures.

Studies show that men are more prone to oral cancer than women. These men are beyond 40 years of age.

The symptoms of mouth cancer are:

- Lump or skin lesion on the tongue, lip or any area of the mouth

- These lumps are usually small and often pale in color. Sometimes is could be discolored or just plain dark.

- It could also come in the form of a hard-edged crack in the tissue of the mouth

- Most of the time, this goes unnoticed because it is painless but as time progresses when the tumor is at its extreme stages, burning sensation in the mouth may occur.

A person must also check if they have:

- mouth sores

- tongue problems such as the abnormal aftertaste of the food he eat

- a difficult time swallowing

If the condition of the patient takes a downward turn, the treatment is for the surgical excision of the tumor. But that is if it is small enough. If not, radiation therapy is the alternative way. If it is an advanced tumor, the treatment is chemotherapy. But the chemotherapy for oral cancer is a combination of both surgery and radiation therapy.

Because of the side effects that can occur during surgery for larger cancers, the structure of the neck and head must be taken care of. That is required to give a functional result.

Those who can survive oral cancers are 50% for those who have theirs at the advanced state. Those who are in stage 1 are 90%, that is why early detection helps in the survival of those afflicted.

Rehabilitation follows after cancer treatment. These are movement, swallowing, chewing and speech exercises. These can help the patient use their mouth in a normal way again.

Most do not notice changes in their skin until a lesion or other discoloration has become large enough to be distracting. A new spot ignored could be a melanoma developing and more than just a new age spot in those who are older. Any new mole or abrasion that takes longer to heal than usual, for anyone, should be cause for concern. What one might think is just a sudden change in their skin, or a suspicious mark, that appears out of nowhere and long sunburn could be the symptom of something more serious.

Given the exposure an average person’s skin receives on a normal day, it is unlikely that much concern should be placed on the skin’s daily wear and tear. Tanning salons and overexposure during warm summer months, even snow ski trips can cause skin conditions that you could be unaware of till it was too late. A check up by a dermatologist once in a while would be wise if you are an outdoors type individual.

Watch for changes in the feel of your skin, that spot on your leg you thought a small thing, might be growing larger and you should find out why. A birthmark that changes shape, the color of a mole, and any unusual skin growth, all should be notification that it is time to ask a doctor what they are.

The American Caner Society has a list of rules to go by and what to watch for should you suspect something is happening with your epidermis. It’s called the ABCD Rule to evaluate any suspicious changes in your skin.

A is for Asymmetry, which is when one half of a mole or skin growth doesn’t look like the other.

B is for boarder irregularity meaning that you see ragged or notched even blurred edges to a skin growth.

Color is the C and the easiest to spot cause the pigmentation in a mole or growth changes shades or has dashes of red or gets a blue mottled appearance.

And lastly, D is for diameter. It has grown from the last time you looked and it’s gone from the size of a pencil to surprisingly large. A physician should look at any mole or growth that grows considerably in size.

Never second guess yourself if you see something strange develop on your body. It may just be a discoloration and mean nothing, but don’t take that chance. If it looks strange and you’ve never seen it before, go have it checked out. Better to be anxious and healthy, than to wait till it is too late to do anything.

Not the lethal news it once was, finding a cancer, although still a devastating diagnosis has lost the threat of death that once went with it. Today with the many methods of treatment out there, it is become an almost curable disease and with the many and varied treatments, one can expect to live as close to a normal life as any other person alive.   

While traditional cancer treatment such as chemotherapy and expensive drugs take the front stage in modern medical practice, there have been major developments with many natural cancer cures. Some practitioners stress diet as a positive factor in natural medicine and some link excessive meat eating with many cancers. Also linked have been products such as white sugar dairy products, tobacco and coffee to name a few that you may not have heard about.

Since 1952 Johanna Budwig a German chemist has said that diet has an important role in fighting and curing cancer and research has proven that it plays a vital role in the treatment of cancer. Her research and findings are referred to as the Budwig Protocol or Budwig Diet, which centers around the consumption of foods that have a high linolenic and linoleic acid content. Recommendations are that a person should eat a specific type of diet to better ensure their body is safer from contracting cancer than if they consume a diet of fast food or meals high in calories and carbohydrates.

To help prevent and cure cancer naturally you must keep your immune system strong and consistent. You should try to get out in the fresh air as much as possible and drinking pure water cleanses your body of built up toxins and eating a lot of leafy green and yellow vegetables like carrots and broccoli, and fruits.

We all have the cells that can create a cancer within us and by keeping our immune system up to par is one way to safeguard yourself against a dreaded disease. Staying healthy and eating well allows your white cells to build enough anti-bodies for any attack to the body and keep your immune system running smoothly.

One method of natural cancer cure is to eat nothing but a raw diet. This is choosing meals of raw fruits, garden fresh vegetables, nuts, and sprouted grains should be consumed until your cancer is in remission. Raw food is alive with minerals, vitamins, enzymes, and other ingredients necessary to a healthy immune system enabling your body to fight the cancers cells invading your body.

Many say drinking carrot juice, which is a good source of Vitamin A along with your vegetable meal if you are eating a raw diet, can significantly help your immune system. Studies by Dr. Raymond Shamberger, Professor of Biochemistry at the Cleveland Clinic showed that Vitamin A is one of the most important vitamins in the treatment and cure of many cancers.

Exercise, plenty of fresh air, lots of rest and good eating habits are just some of the methods to combat cancer naturally and have proven effective in many cases of cancer and have seen amazing results. Remember that no matter what method you decide is good for you be sure and see your doctor before you embark on any type of treatment that you are unsure of, regardless of its promised outcome. Your health matters and whatever the choice you make about your treatment should be checked out by a trusted physician.

Carcinoma is a type of cancer that starts in the lining of an organ. Lymphoma, melanoma, sarcomas and carcinoid tumors are other types of cancer but are rare.  

Risk factors

One risk factor that could increase a person’s chances to develop colon cancer is colorectal polyps which is a growth that develops from the lining of the colon.

Another risk factor is if a person has a cancer in other parts of the body. That person’s risk of getting the colon cancer is greater compared to those who do not have any cancer.

Persons with a family history of colon cancer are also more susceptible to risk.

Some studies show that a high in meat, high in fat and low in fiber diet can increase the risk of cancer.

Symptoms

In most colon cancer cases there are no visible symptoms. However, certain changes in bowel habits might indicate the development of colon cancer. If a person is suffering from diarrhea or constipation for a long period of time, that person may consider visiting a doctor for proper check up.

Another symptom is if there is blood in a person’s stool or if there is unexplained anemia.

Persistent pain in the abdominal area could also be an indication of colon cancer.

Unexplained weight loss can also be attributed to this disease.

Reducing Your Risks

In order to reduce the risk of getting colon cancer, you should have your doctor perform a colonoscopy. This is important especially for men and women aged 50 and above. A Colonoscopy may scare most people because the procedure requires cleaning out the colon but this is an effective preventive measure.

If your family has a history of colon polyps or other inflammatory bowel diseases should also undergo colonoscopy even before the age of 50 because they are at a greater risk of developing colon cancer. Those who have a family history of colon cancer should also consider having colonoscopy at an earlier age.

Sigmoidoscopy and barium enema are other tests that can be used to aid in the prevention of colon cancer. Keeping a healthy and balanced diet is also important. It is advisable that you maintain a low-fat, high-fiber diet as this can lower your risk of developing colon cancer.

Another way to prevent colon cancer is to quit smoking and to avoid being exposed to second hand smoke. Studies show that colon cancer is more common in smokers than non smokers.

Taking aspirin daily can also help to prevent a person from developing colon cancer because aspirin gets in the way in prostaglandin metabolism and this prevents cancer and other cardiovascular disease. One 325mg aspirin daily is enough.

Taking 1500mg of calcium a day also shows to be lower the risk of colon cancer.

Selenium is an antioxidant that protects cells from free radicals and is essential for the functioning of the immune system and the thyroid gland. Taking selenium or other antioxidants daily is also recommended, along with a daily multi-vitamin.

There has been research on the anti cancer capabilities of tumeric. Tumeric is one of the main ingredients in curry powder so adding this to your dishes once in a while may help in the fight against cancer.

These are some ways to lower the risk of developing colon cancer although there is no 100% guarantee that you will not develop the disease if you follow all of these.

And remember to always consult your physician when you have questions about health issues no matter how minor you think they are.
