Precursors of Cancer and Cancer Prevention
A weak or non-functioning immune system, poor health, an unhealthy environment and advanced age (over 80) can contribute to cancer. In the majority of people cancer can be prevented with proper lifestyle which consists of a low-entropy diet, exercise, sleep, stress reduction, etc. In most cases cancer develops slowly over many years. With a positive change of lifestyle and healthy environment this trend can be reversed in the majority of cases (probably in 90% -> 95%) - the cancer will shrink and eventually disappear.
