Epic failNo it's not. Prevention cannot stop cancer.
Win.You are not just born to have cancer. You may have a genetic predisposition to cancer but it is life style that makes that predisposition a reality. It's called epigenetics, where your genes express themselves and your DNA can be altered thru environmental inputs.
If you eat garbage your whole life, smoke cigarettes, and abuse your body chances are you will get cancer, so is that environmental or is that genetic?
I bet if you looked at a wide range of cancer patients, there was something they did, ate, used or were exposed to which made it happen. It is so hard to avoid it in today's world with environmental pollution, toxins in our food and products we use.
I don't believe cancer is just something that happens, anyone I have known personally with cancer lived unhealthy lifestyles, even if they didn't realize their lifestyle was unhealthy as an outsider looking in I can see what may have caused what they had.
Not a cure in and of itself, but evidence has shown it can reduce tumors. Synergy with other drugs or substances may work toward the cure goal. Certainly putting the mind in a better state allows the body to combat disease. I don't believe that it cured my leukemia, but I didn't start truly recovering from all the anti-rejection drugs, pain pills, etc etc until I convinced my parents that smoking was beneficial and could do it openly. I then took myself off all the poison and haven't looked back since. 6 years post transplant now.
