I believe that a diet high in fat and meat is linked to high rates of colon and prostrate cancer. Cancer is the abnormal and uncontrolled cellular proliferation. Prostrate cancer is the common cause of cancer in men and may be detected by rectal examination, PSA blood test, ultrasound, and biopsy. Colon cancer is the cancer of the large intestines which is the last part of the Gastrointestinal tract.
