Bowel cancer, also known as colorectal cancer, is a type of cancer that starts in the large intestine (colon) or rectum. It usually begins as small, non-cancerous growths called polyps, which can eventually become cancerous over time. Symptoms of bowel cancer can include changes in bowel habits, blood in the stool, unexplained weight loss, or persistent stomach discomfort. Early detection through screenings like the faecal immunochemical test (FIT) can help find the cancer before symptoms appear, making it easier to treat. Bowel cancer is more common in older adults, but lifestyle factors like diet and exercise can also influence the risk.
