Well, actually, this about the causes of cancer is just a theory.
I know many people who don´t obey these advice and live many more years than those who live their lives in the midst of a strict anti-cancer food plan.
We have seen athletes die in the middle of the field.
I have seen smokers or alcoholics live more than 80 years and die of pneumonia or liver cirrhosis, not cancer.
We have seen children under the age of 10 die of cancer without ever drinking alcohol or smoking.
Cancer is as genetic and biological as mitosis.
