The development of colorectal cancer is influenced by significant risk factors, including lifestyle factors such as a diet rich in saturated fats and red meat, obesity, smoking, and alcohol consumption, as well as the presence of intestinal polyps. During screening colonoscopies, the early removal of polyps before they undergo malignant transformation is a critical strategy for disease prevention. Furthermore, a history of breast or ovarian cancer in women significantly increases the risk of colorectal cancer. Therefore, for individuals with a history of breast or ovarian cancer, colorectal cancer screening is recommended to commence earlier than the general advice of age 50.
