6 Facts About Colon Cancer Cancer of the colon is a serious disease that affects the large intestine (colon). The colon is a long, coiled tube that removes waste from the body. Cancer of the colon can be either benign (noncancerous) or malignant (cancerous). Most colon cancers begin as small, noncancerous (benign) polyps on the inner lining of the colon. Over time, some of these polyps can become cancerous. That’s why it’s important to have regular colonoscopies, which can detect and remove polyps before they turn into cancer. Cancer of the colon can be a very slow-growing cancer, which is why regular screenings are so important. If caught early, colon cancer is highly treatable. However, if it’s not caught early, colon cancer can be deadly. Symptoms of colon cancer can include: -A change in bowel habits, such as diarrhea, constipation, or a change in the consistency of your stool -Rectal bleeding or blood in your stool -Persistent abdominal pain, cramping, or discomfort -Weakness or fatigue -Unexplained weight loss If you experience any of these symptoms, it’s crucial that you see a doctor as soon as possible. Colorectal cancer specialists will be able to provide a professional diagnosis.
