Which is listed as a complication of cancer involving the colorectal system?

• A. Liver failure
• B. Secondary colorectal tumor or complete intestinal obstruction
• C. Kidney failure
• D. Osteonecrosis

Answer: (B)

Complications that involve the colorectal tract occur when cancer directly affects the colon or rectum. A tumor in this area can spread within the colon (secondary colorectal tumor) and impair function, or it can grow enough to block the intestinal lumen, causing a complete obstruction. Both scenarios directly involve the colorectal system and explain symptoms like cramping, distension, and altered bowel movements. Other options describe problems in organs not part of the colorectal tract itself (for example, liver or kidney issues) or a condition like osteonecrosis, which is unrelated to colorectal cancer. These are not colorectal system complications, so they don’t fit as well as the described issues in the colon or rectum. Therefore, the option mentioning a secondary colorectal tumor or complete intestinal obstruction is the best fit.
