Natural cancer treatment doctors believe that the primary cause of cancer is an unhealthy diet and lifestyle. Their solution to getting rid of cancer involves eliminating the root cause of cancer and not just the symptoms. Contrary to what most of us consider as a nutritious diet, an average person's diet is made up of toxic food like processed food, dairy products and meat. This poisons and impairs the immune system and causes diseases. By keeping the immune system up, our bodies can heal itself and annihilate the cancer cells naturally from within.
