Colon Cancer :
When any part of the large intestine is affected by the growth of malignant cells, the condition is called colon cancer. In the initial stages of colon cancer, groups of cells clump together in the large intestine. Such a clump is called a polyp, and it is not cancerous but can turn cancerous over time. If colon cancer develops, it may not immediately cause symptoms. The size and location of the tumor can determine the kind of symptoms that manifest. Unusually frequent constipation or diarrhea, bleeding from the rectum, and weight loss are some common signs of this disease. Colon cancer can also result in ongoing discomfort in the belly. This disease is typically diagnosed with a colonoscopy procedure. It involves the insertion of a flexible and thin tube via the anus to view the rectum and colon. Viable treatment options include surgery and chemotherapy.
