WHAT IS COLON CANCER
Author:The colon is the part of the gastrointestinal system where the waste product is stored. The rectum is the ending of the colon adjoining to the anus. Collectively, they build a long, muscular tubing called the large intestine (a.k.a. the large bowel). Tumors of the colon and rectum are growths developing from the inside wall of the large intestine. Benignant tumors of the large intestine are called polyps. Malignant tumour* of the large intestine are called cancers. Benignant polyps don’t intrude on nearby tissue or disseminate to additional parts of the body. Benignant polyps can be easily took out during colonoscopy and are not life-threatening. If benignant polyps are not took out from the large intestine, they can turn malignant (cancerous) over time. Most of the cancers of the large intestine are considered to have originated from polyps. Cancer of the colon and rectum (in addition to referred to as colorectal cancer) can occupy and harm adjoining tissues and organs. Cancer cells could also break off and spread to additional parts of the body (specified liver and lung) wherever new tumors take shape. The disseminate of colon cancer to distant organs is called metastasis of the colon cancer. When metastasis has took place in colorectal cancer, a complete cure of the cancer is improbable.
