Colon is our large intestine located at the lower part of our digestive system. Therefore, rectal is last 12 centimeter below the colon. When uncontrollable cancer cells increase its growth in the colon and rectal, it is called colorectal cancer.

Most common cases of colon cancer start as small, noncancerous (benign) clumps of cells called adenomatous polyps. Unfortunately, these polyps can also become cancerous. If they begin spreading and occupying healthy tissue this is called metastasis. This is a more serious stage of cancer. Polyps can be prevented from becoming malignant if regular checkup and healthy diet are observed. Screening test would be a great help to stop polyps from multiplying.
