The symptoms of rectal cancer recurrence can include changes in bowel habits and stool characteristics, possibly presenting as rectal bleeding, increased frequency of bowel movements, a sensation of heaviness in the anus, and changes in stool shape, such as narrowing. The second symptom may be abdominal pain, particularly persistent and subtle pain. The third symptom involves palpable abdominal lumps or masses, especially with right-sided colon cancer. The fourth symptom is intestinal obstruction, which can occur if the bowel is blocked due to the recurrence of rectal cancer, leading to symptoms of intestinal obstruction. The fifth symptom, if the recurrent rectal cancer has metastasized, may lead to symptoms at the respective metastatic sites.
