Surgery is the main treatment for most colon cancers and an essential part of treatment for rectal cancer. Patients usually arrive with the same questions: which operation, how it is done, whether a stoma will be needed and how long recovery takes. This guide by New City Clinic sets out the general answers; your own plan is made by the tumour board after your tests have been assessed.
How is the operation chosen?
The decision depends on where the tumour sits and on its stage. For colon cancer, the affected segment of bowel is removed together with the nearby lymph nodes, and the two ends are joined. For rectal cancer, a pelvic MRI shows how deep the tumour reaches; in locally advanced disease, radiotherapy and drug treatment are often given first and surgery follows. The order of these steps is decided at the tumour board, where surgeons, oncologists, radiologists and pathologists review the case together.
Keyhole, robotic or open surgery?
Many patients are suitable for laparoscopic (keyhole) surgery, and some centres use robotic systems, particularly in the narrow space of the pelvis. Open surgery remains the right choice in some situations, for example with very large tumours or after several earlier operations. Whatever the approach, the aim is the same: to remove the tumour with clear margins and the lymph nodes that belong to it. The surgeon explains which approach is planned for you and why.
Will I need a stoma?
After most colon cancer operations no stoma is needed. In rectal surgery a temporary stoma is often made to protect the new join while it heals; it is usually closed in a second, smaller operation some weeks or months later. A permanent stoma is needed in a minority of patients, mainly when the tumour lies very close to the anus. Your surgeon discusses this openly before the operation, and a stoma care nurse teaches you how to manage it.
Hospital stay and recovery
You are encouraged to get out of bed and walk from the first day, and eating is restarted step by step. If recovery is uneventful, the hospital stay is usually about a week. The pathology report on the removed tissue arrives within one to two weeks and determines whether drug treatment is recommended afterwards. International patients should plan to stay in Istanbul until the first check-up and the pathology result; your surgeon tells you when it is safe to fly.

Is chemotherapy always needed after surgery?
No. It depends on the stage and on the pathology findings; in early stages it is often not required.

In many cases yes. Your reports and the tumour board’s recommendation are prepared in English so that your oncologist at home can continue the plan.
