Colon cancer cases are increasing among younger adults, and prolonged sitting may be one of the overlooked reasons behind the trend, according to Dr. Priyam Bordoloi. In a post on X, the doctor highlighted that while genetics often gets the blame, medical evidence increasingly points to a common modern habit—spending most of the day sitting—as a significant independent risk factor. He also stressed that a 45-minute gym workout cannot fully offset the health effects of sitting for long hours.
