Colorectal Cancer Surgery in Delhi: What Patients and Families Should Know
Medically reviewed by Dr Saurabh Bansal, GI, laparoscopic and bariatric surgeon, Delhi Medical Council Reg. No. 37887. Last updated: 18 October 2026. This guide was prepared with AI assistance and reviewed by the doctor; it is general information and not a substitute for a consultation.
Quick answer
Surgery is the main treatment for most colon and rectal (colorectal) cancers that have not spread widely. The operation removes the affected part of the bowel with its lymph nodes and joins the healthy ends. Many operations can be done laparoscopically. Rectal cancer often needs chemotherapy and/or radiotherapy before surgery, planned by a multidisciplinary team.
Warning signs to get checked
Blood in the stool or black stools
A lasting change in bowel habit
Unexplained weight loss, tiredness or anaemia
Abdominal pain or a feeling of incomplete emptying
These symptoms have many causes, but they should be assessed by a doctor, often with a colonoscopy.
Tests before surgery
Colonoscopy with biopsy confirms the diagnosis. CT scans of the chest and abdomen check for spread; MRI of the pelvis is used for rectal cancer. Blood tests, including CEA, and a fitness assessment complete the plan.
Types of operation
Right or left hemicolectomy / sigmoid colectomy for colon cancer, depending on the tumour's position.
Anterior resection for many rectal cancers, sometimes with a temporary stoma to protect the join.
Abdominoperineal resection when the tumour is very low and the sphincter cannot be preserved, which needs a permanent colostomy.
Recovery
Most patients follow an enhanced-recovery plan: early walking, early feeding and good pain control. Hospital stay is commonly several days. The removed tissue is examined to decide whether further treatment such as chemotherapy is needed, followed by regular surveillance.
What affects the cost?
Cost depends on the type of operation, laparoscopic or open approach, the hospital and room category, ICU needs, length of stay, any stoma care, and additional treatment such as chemotherapy or radiotherapy, along with insurance cover. A personalised estimate is given after consultation.
Frequently asked questions
Can colorectal cancer surgery be done laparoscopically?
Yes, many colon and rectal cancer operations can be performed laparoscopically when the tumour and patient are suitable. Your surgeon will discuss this after reviewing scans.
Will I need a stoma bag?
Not always. Some patients need a temporary stoma to protect the join, which is usually reversed later. A permanent stoma is needed only in specific situations, such as some very low rectal cancers.
Will I need chemotherapy after surgery?
It depends on the stage found on examination of the removed tissue. The decision is made with the oncology team.
Is colonoscopy needed after treatment?
Yes. Regular follow-up with blood tests, scans and colonoscopy is part of surveillance after colorectal cancer surgery.
