COLORECTAL CANCER Two Types • Colon cancer – Starts in the Colon (Large Intestine) • Rectum Cancer – Starts in the rectum • Also known as bowel cancer. What is cancer? • Our bodies grow through cell division (mitosis) • Once we don’t need them to divide and grow any more, they stop. • Cancer is when our cells keep reproducing when we don’t need them to, forming a tumour. • Benign tumours stay in one part of the body and can be removed. • Malignant tumours spread uncontrollably. Polyps • Tiny growths that form on the inside lining of the colon. • Can grow into cancers. • Can sometimes be noticed or felt as grape like growths. What should you do if you notice such a growth? (Or any growth that is abnormal?) • GO TO THE DOCTOR! • 75% of colorectal cancer cases are preventable through diet, exercise and early screening. Causes/Risk Factors • High fat intake (familiar?) • Excess red meat (90g+ per day) • Excess overcooked meat. Preventative Measures • Antioxidants – found in vegetables and legumes. • Carotene-rich (yellow, orange, red vegies) • 5 serves a day. • Fibre – Allows food matter and waste to pass through colon quicker. Matter that stays in the bowels can become a polyp.
