When is bowel resection recommended for bowel cancer?

A surgeon removes the bowel segment containing the tumour together with nearby tissue and lymph nodes, then joins the remaining ends when appropriate. Sometimes a temporary or longer-term stoma is needed to divert stool while the bowel heals or when joining the ends is not suitable. The plan depends on whether the cancer is in the colon or rectum, its position, nearby structures, scan findings, and the person’s fitness for surgery. Drug treatment or radiotherapy may be advised before or after surgery.

The surgical team reviews scans, pathology, medicines, nutrition, bowel function, and other health conditions. Ask what part of the bowel will be removed, whether a stoma is possible, how recovery will be supported, and whether additional treatment is expected. A stoma nurse can explain appliances and skin care. Do not stop blood thinners or other medicines without specific instructions from the treating team.

Seek urgent care for severe or increasing abdominal pain, a swollen abdomen, repeated vomiting, inability to pass stool or gas, heavy rectal bleeding, fainting, or fever with worsening illness. These symptoms may indicate obstruction, bleeding, infection, or another complication. After surgery, contact the team promptly for wound redness, leakage, persistent vomiting, or a stoma that becomes unusually swollen or stops working.

Where is the tumour and how much bowel may be removed? Could I need a stoma? What are the alternatives, and how will surgery fit with chemotherapy or radiotherapy?
