Colorectal Cancer Surgery — Colon & Rectum

Modern colon and rectal cancer surgery aims for complete removal with clear margins — preserving normal bowel function and the sphincter wherever oncologically safe.

What it covers
Cancers of the colon and rectum
The goal
Complete oncological clearance — with sphincter preservation wherever safely possible
Planning
Colonoscopy and staging first; tumour-board reviewed; chemo/radiation sequenced where needed
Where
Apollo Hospitals, Sarjapur Road, Bengaluru

Warning signs worth evaluating

Colorectal cancer is common, and highly treatable when found early — colonoscopy is the definitive evaluation for these symptoms. Early assessment helps guide care.

The "will I need a bag?" question

It is the question most patients carry in silently, so here is the honest answer: with modern sphincter-preserving techniques, a permanent stoma (bag) is avoided in the majority of rectal cancer cases where the tumour's position allows. Some patients need a temporary stoma while healing completes, which is later reversed. Where a permanent stoma is genuinely the oncologically safe option, that is discussed openly beforehand — never a surprise after surgery.

The surgery

Colon cancers are treated by removing the affected segment with its lymph nodes (colectomy); rectal cancers with precise techniques (LAR/APR as anatomy requires) that respect the planes protecting nerve function. For rectal cancer, radiation or chemotherapy often comes before surgery — the sequence is decided by the tumour board after staging. Minimally invasive approaches are used where oncologically appropriate.

Blood in the stool deserves examination, not assumption — piles and cancer share this symptom, and only evaluation tells them apart.

Frequently asked questions

Will I need a permanent bag after rectal cancer surgery?

In the majority of cases where tumour position allows, sphincter-preserving surgery avoids a permanent stoma. Some patients need a temporary, reversible stoma during healing. Whatever applies to you is discussed openly before surgery.

Is blood in the stool always piles?

No — piles and colorectal cancer share this symptom. Bleeding needs examination, and colonoscopy where indicated, before assuming the cause.

Is chemotherapy or radiation needed before surgery?

Often for rectal cancer, treatment before surgery improves outcomes of the operation — the sequence is decided by the tumour board after staging.

Can colon cancer be cured?

Colorectal cancer found early is among the most treatable cancers, and surgery with clear margins is central to that. Individual outlook depends on stage and is discussed honestly after staging.
