Colorectal cancer is more common in those over 50, but it can affect younger people too. Learning the symptoms could raise the chances of potentially life-saving early detection for people of all ages.  With an average age of diagnosis of approximately 70, colorectal cancer is considered to be early onset in those who develop it at under 50 years of age, with people with family histories or existing inflammatory bowel disease at higher risk. While genetic counseling for those at risk can lower the chances of developing colorectal cancer, learning the symptoms — and seeing a doctor if and when they present — is key to raising the odds of potentially life-saving early diagnosis. “Symptoms include changes in bowel habits, blood in bowel motions, abdominal pain, weight loss and fatigue,” Matthew Kalady, MD, says. “The key is to take all of these symptoms seriously. Bleeding of any kind, especially, is not normal and should be evaluated by a professional.”
