As one of the principal health concerns of all people, and one of the major areas of abuse & fraud by the medical establishment, I am morally bound to give this topic priority treatment.

The principal requirements to avoid/cure the causes [tumors are symptoms of cancer, not its cause] of cancer are:
1.  Alkalinity [cancer cannot get started in an alkaline bodily environment, and, if started, finds it difficult to continue existing]; [The Acid-Alkaline Food Guide  by Susan BROWN] [The Acid Alkaline Balance Diet by Felicia Kliment]
2.  Omega 3 dominence: should be 1:1 or 1:3 vs. other oils combined [check out the Budwig protocol -- also now adding hyperthermia for intractable cases]
3.  Heavy Metals / Toxins cleared  [most central & critical for all illness and disease]
4.  Vitamin D [a master hormone] at high levels: serum 25-hydroxyvitaminD above 80 ng/ml [there is no known case of standard (any?) types of cancer starting if D level is over 80]; take 5,000 IU of D3 daily with nutritious diet
5.  Teeth -- especially root canal teeth -- repaired/extracted [Root Canal Cover-Up by George E. MEINIG, DDS, FACD]
6.  Diet: vegetables, fruit, seeds, nuts, small fish, 100% whole grains [preferably not wheat] in heavy predominance [90%] with no processed cane sugar [lo han and stevia OK]

Other Books: As ones immune system is critical to fighting cancer [radiation & chemo destroy it], must implore that everyone read:
A.  Vaccine Safety Manual by Neil Z. MILLER with ultra-critical 9 page introduction [pages 7-15] by Dr. Russell BLAYLOCK [neurosurgeon] ISBN: 978-1881217-37-4 by New Atlantean Press. This intro contains the most important FACTS on vaccines that exist; esp. page 8 on excitotoxicity.

C & glutathione; etc.]  <>  1-800-834-4325  and his book: Dr. Gallagher's Guide to 21st Century Medicine
