How effective is rectal cancer surgery for rectal cancer?

Rectal resection removes the tumour with a margin of healthy-looking tissue and nearby lymph nodes. The surgeon chooses an approach based on how low the tumour is, whether it has grown through the rectal wall, and whether nearby organs are involved. The bowel may be joined again, or a temporary or lasting stoma may be needed to let stool leave the body safely. Some people receive chemotherapy or radiotherapy before or after surgery to shrink disease, reduce the chance of return, or treat cancer cells outside the operation area.

Ask the colorectal team which operation is proposed, whether the sphincter can be preserved, and why a stoma might be needed. Discuss bowel preparation, medicines, nutrition, walking, breathing exercises and pelvic-floor support. Ask how the team will assess the removed tissue and how that result may guide further treatment. A stoma nurse can teach pouch care and help you plan practical support at home.

After surgery, contact the team for fever, worsening abdominal pain, repeated vomiting, a swollen abdomen, increasing redness or drainage from the wound, or a stoma that changes colour. Seek urgent help for heavy bleeding, fainting, chest pain, or severe breathing difficulty. A new inability to pass stool or gas should be assessed promptly.

Where is my tumour and which resection fits its position? Will I need treatment before or after surgery? Is a temporary or lasting stoma likely? How might the operation affect bowel control, urinary function and sexual function? What support is available during recovery?
