Abstract

Cancer is a preventable disease. The fact that only 5- 10% of all cancer cases are due to genetic defects and that the remaining 90-95% are due to environment and lifestyle provides major opportunities for preventing cancer. Prevention of cancer can take place on several different levels: primary prevention addresses the cause of cancer so disease does not occur, secondary prevention identifies disease before the onset of symptoms and keeps it from becoming more extensive and tertiary prevention reduces complications and progression of disease once it has become clinically apparent.
