1. Cancer may be a body's predictable response to innumerable attacks from cancer-causing toxins in our air, water, and food system including newly introduced GMO foods.
2. Cancer cells are caused/aggravated by inflammation and an immune system that becomes overwhelmed  and insufficient to rid the body of these cells.
3. Cancer cells are tricky in that they have a + charge energy coating covering a - charge cell.  White blood cells do not recognize the + coating as a danger and therefore the white blood cells do not perceive the threat.
4. The immune system and only the immune system rids us of cancer effects.  Strategies such as surgery of cancerous tumors, radiation, and chemotherapy attempt to reduce the number of cancer cells to give the immune system a fighting chance.
5. Often the approach in mainstream medicine is to "fight the cancer".  Ayurveda and other Natural Healing approaches want to understand the causes and work with shifting those so that our miraculous body can heal itself. 

This information was gleaned from the video series "The Truth about Cancer".  It features many doctors who have rejected what their medical training has offered on treating cancer in favor of natural approaches that they state are showing more effectiveness at treating and curing cancer.    

1. Eat an alkaline diet.  Whole vegetables and fruits are generally more alkaline.  Especially go for beets, broccoli, cauliflower, kale, spinach, sea vegetation (iodine) , berries, grapes, lemons.  Almonds, Brazil nuts, cinnamon, and ginger are also recommended.   eat real not processed foods. Ayurveda considers cooked food more easily digestible. Use ph strips on your tongue to test your body's alkalinity.
2. Eliminate processed sugars.  For awhile we have known that cancer feeds on sugar.  To detect cancer in a PET scan, D-glucose is injected because it is taken up so quickly by cancer cells.  There is new research that gets more specific about sugar.  There are what is called right-spinning molecules and left-spinning molecules.  Have you noticed the "L" in front of amino acids like L-lysine?  The L stands for left-spinning and that is good.  Any unnatural. processed sugar is right-spinning and we must avoid.   Natural, unprocessed sugars like honey, molasses, maple syrup, sugar cane, and natural sugars in fruits are left-spinning and new research is proposing that these do not feed cancer.  Blueberries, for instance, are often promoted to be cancer preventing. It's the left spin. Still, be modest even with natural sugars.
3. Eliminate high-gluten grains like wheat, rye, and spelt-even if they are whole grains.   Enjoy non-gluten grains such as rice, buckwheat, quinoa, millet and amaranth.
4. Reduce dairy.  Dairy is high in casein protein which has been found to be cancer-promoting.  Dairy can be acidifying and cause inflammation.
5. Use organic olive, coconut, and avocado oil.  Coconut oil has a mild antibacterial/antifungal effect so is helpful if the immune system is compromised.  Also, it is cooling which helps to balance inflammation. Avoid GMO and processed oils and hydrogenated (hard) oils.
6. Drink freshly made vegetable juice, clean water, herbal tea, and lemon water.  Avoid processed drinks of any sort. Helpful herbal teas include green, sage, mint, or ginger.  Carrot or carrot-beet juice strengthens the immune system.  When juicing, keep is simple--just a few vegetables which makes them easier to digest.

You are probably already doing many of these at least to some extent.  To prevent cancer, do more.  To deal with cancer be even more vigilant.  Read more at Nutritional Healing from Cancer:  The Fundamentals of an Alkaline Diet.  Go here for a downloadable acid-alkaline diet food chart.
