Why awareness and screening matter more than ever 

Colorectal cancer has traditionally been considered a disease affecting older adults, but that perception is rapidly changing. According to Healthline, nearly half of new colorectal cancer diagnoses are now occurring in adults younger than 55, a troubling shift that researchers across the country are working to understand. 

Data from the American Cancer Society shows colorectal cancer is now the leading cause of cancer-related death in men under age 50 and the second leading cause in women under age 50. Even more concerning, many younger patients are diagnosed at later stages because symptoms may be overlooked or attributed to less serious conditions. 

Experts say several factors may be contributing to the rise in early-onset colorectal cancer. Diets high in processed foods and red meat and low in fiber may increase risk. Sedentary lifestyles, rising obesity rates, and metabolic conditions such as diabetes and chronic inflammation are also being studied as possible contributors. Researchers believe many cases in younger adults are not inherited, suggesting lifestyle and environmental factors may play an important role. 

Another challenge is that symptoms in younger adults are sometimes dismissed. According to physicians cited by Healthline, warning signs can include rectal bleeding, unexplained abdominal pain, persistent changes in bowel habits, fatigue, or iron-deficiency anemia. Any of these symptoms should be evaluated by a healthcare professional. 

Because of these trends, screening guidelines have changed. The American Cancer Society now recommends that people at average risk begin colorectal cancer screening at age 45. 

In Western New York, specialists emphasize that early detection dramatically improves survival. With greater awareness, healthy lifestyle habits, and appropriate screening, many colorectal cancers can be prevented or detected at an early, highly treatable stage.
