What is most common area of the colon for cancer?

The most common area of the colon for cancer is the sigmoid colon, which is the section closest to the rectum. Colorectal cancer often develops in this region due to factors such as the accumulation of polyps and changes in the lining of the colon. Other common sites include the ascending and descending colon, but the sigmoid colon remains the most prevalent location for malignant tumors. Regular screenings can help detect changes early in these areas.
