Colorectal adenomas are precancerous growths in the colon or rectum that have the potential to develop into colorectal cancer. They are typically detected during screening colonoscopies and are categorized based on their size, shape, and other characteristics. Colorectal adenomas are considered a significant risk factor for developing colorectal cancer, and the removal of these adenomas during a colonoscopy has been shown to reduce the risk of developing cancer. Research in this area focuses on understanding the development of colorectal adenomas, identifying risk factors for their formation, and improving screening and prevention strategies to reduce the incidence of colorectal cancer.
