Surgery for colon cancer

The surgeon usually reconnects the healthy bowel ends. Some people need a stoma, which may be temporary or long term depending on tumour location, the operation, healing and safety considerations.

Scans, colonoscopy findings, biopsy results and general health help define the operation. Surgery may use keyhole, robotic or open techniques; the suitable route depends on anatomy, previous operations, tumour features and the surgeon's judgement.

Removed tissue is examined to confirm the tumour's features, margins and lymph-node findings. That information helps the oncology team decide whether additional treatment should be discussed.

Tell the team about every medicine and supplement, allergies, previous anaesthetic problems and conditions affecting the heart, lungs, kidneys or blood sugar. Follow the hospital's instructions on eating, drinking, bowel preparation and medicines exactly.

After surgery, pain control, early movement, breathing exercises, nutrition and clot prevention support recovery. Bowel habits can be unsettled while the gut adapts. Follow lifting, wound and driving advice, and use the named contact if recovery differs from the discharge plan.

Contact the surgical team urgently for fever, increasing abdominal pain or swelling, repeated vomiting, a wound that becomes red or drains fluid, inability to eat or drink, or a sudden reduction in stoma output with cramps.

Call emergency services for severe breathing trouble, chest pain, collapse, uncontrolled bleeding or sudden severe abdominal pain. New calf swelling or pain also needs urgent assessment because it can accompany a blood clot.

Ask what will be removed, which operative approach is planned, how likely a stoma is in your individual case, and what could make the surgeon change the plan during the procedure.

Request clear guidance on pain relief, eating, activity, return to work, pathology follow-up and the symptoms that require a same-day call.
