Summary
A pre-cancerous polyp found and removed during screening — a colon cancer prevented before it could form.
- Procedure
- Colonoscopy & Polypectomy
- Organ
- Colon
- 01
Presentation
A patient in their 50s with a family history of colon cancer and subtle change in bowel habit, anxious about screening.
- 02
Investigations
Given the family history, a screening colonoscopy was advised despite minimal symptoms.
- 03
Findings
A flat, broad-based polyp was identified in the colon — exactly the kind of lesion that can silently progress to cancer over years.
- 04
Strategy
Rather than just biopsy and wait, the polyp was removed completely in the same sitting (polypectomy), avoiding a second procedure.
- 05
Procedure
The polyp was lifted and excised endoscopically in full, with clear margins, during the same colonoscopy.
- 06
Outcome
Pathology confirmed a pre-cancerous lesion removed completely — a cancer prevented.
- 07
Follow-up
A surveillance schedule was set so any future polyps are caught equally early.
What this case teaches
Screening colonoscopy does not just find cancer early — by removing polyps, it can stop cancer from ever developing.

WHY DWARIKA HOSPITALABOUT THE HOSPITAL
Four promises.
One standard.
What every patient can expect here — from the first call to the last follow-up.
01.
Super-specialist led
Surgery here is performed by MCh-qualified surgical gastroenterologists, not general surgeons operating outside their specialty.
02.
Keyhole by default
Laparoscopic and scarless techniques are the standard approach, reserving open surgery for cases that genuinely need it.
03.
One team, one plan
Diagnosis, surgery, nutrition and follow-up sit under one roof — you are not handed between disconnected clinics.
04.
Counselling before consent
Every patient is told what the operation can and cannot achieve, with costs stated upfront, before anything is scheduled.
