Lifestyle changes that have been shown to decrease cancer risk include preventative medical screening tests, regular exercise, deep breathing exercises, adequate sleep, regular internal cleansing, maintaining proper weight, stopping smoking and alcohol use and decreasing exposure to harmful chemicals and the sun.

Water should be fluoride free and de-chlorinated for drinking, washing foods and bathing.  Avoid x-rays, microwaves and electronic equipment, which are all sources of low-level radiation.  Avoid chemicals in personal hygiene products, cleaning compounds and weed control products.  Avoid iron supplements unless prescribed by a health professional.

The factors that can contribute to an individual developing cancer are numerous and sometimes very poorly understood. Genetics were once thought to play a much more important role then we now know. Studies have shown that genetic factors are only a minor contribution in the development of breast, prostate and colon cancers.

Diet and lifestyle, as well as environmental toxins play a fundamental role in the prevention of almost all forms of cancer. Red meat consumption can contribute to colon cancer, as well as breast cancer, especially if it is charred. Broiling, frying and grilling red meats releases chemicals called advanced glycation end products (AGE's). These chemicals are absorbed into the blood stream causing oxidative damage, stress and ultimately inflammation and damage. It has been suggested that marinating meats for a minimum of 2 hours before grilling can significantly lessen the toxic burden. Increasing fibre in one's diet has been shown to be especially helpful in the prevention for both colon and prostate cancers in men and breast cancer in women. Fibre decreases colonic pH, increases the production and efficiency of immune cells in the gut (GALT) and decreases transit time, therefore decreasing toxic build-up in the body, all serving to protect the body from cancer.

Diets high in whole grains, fruits, vegetables and beans and lentils can still fall short of the recommended fibre daily intake. It may be helpful to introduce a fibre supplement if you feel your diet is falling short. Diets rich in cruciferous vegetables, tomatoes, garlic, onion and carrots, as well as herbs like ginger, cayenne, rosemary, oregano and curcumin (tumeric) have abundant cancer fighting potential. Obesity in general increases the risk of breast, endometrial, cervical, ovarian and gallbladder cancers in women, while also increasing the risk of colon and prostate cancers in men. Weight loss may be essential to reduce your risk of these types of cancer. Stress is also said to be a significant contributing factor. Practice stress reduction techniques that resonate with you, whether it be yoga, meditation, deep breathing, or massage. They can strengthen your body's defences against various disease, including cancers.

Stress puts a burden on the immune system and taxes the body’s resources, making it more susceptible to cancer.  Use whatever stress-busting methods work for you to decrease your stress level.  Strong support from family friends and support groups has been shown to increase longevity in those suffering from cancer.

Increase the following things in your diet, filtered water, raw fruits and vegetables, whole grains, nuts and seeds, soy, and wild, ocean going fish.   Seven to ten daily servings of fruit and vegetables can reduce cancer risk by about 30 percent.  Onions and garlic enhance the immune system and fight cancer.  Consume them whenever possible or use supplementation.  Limit the consumption of animal products, processed foods, caffeine, alcohol, salt, bleached flour products and sugar, tobacco and drugs.

In terms of treatment, there are simply no supplements on the market that have the research behind them to claim "cure". That being said, there are a number of supplements that can help to lessen side effects and support the body through the damaging effects of traditional therapies, like chemotherapy and/or radiation. Supplements high in antioxidants and many mushroom extracts have been shown to be particularly useful in preventing free radical and supporting the body's immune system in its cancer fighting abilities respectively.
