[Rectal cancer].
The most common symptom of rectal cancer is bleeding. The average diagnostic delay is half a year. Colonoscopy, magnetic resonance imaging of the pelvis and computed tomography scanning of the body are carried out before the operation to assess the extent, and the level of carcinoembryonic antigen is determined from the serum. In cancers grown through the intestinal wall or spread to the mesorectal lymph nodes, local radiotherapy is applied preoperationally. The surgical operation involves total mesorectal excision with low-rectal anastomosis. Cytotoxic chemotherapy of a disseminated cancer will improve the quality of life.
