Colon & Rectum Knowledge Centre
Everything about the colon and rectum in one place — piles, rectal prolapse, colon and rectal cancer, explained in plain language.
Understanding your Colon & Rectum
The colon and rectum can be affected by very common, very treatable problems like piles, as well as rectal prolapse and colon or rectal cancer. This hub brings all of it together — plain-language explanations, screening colonoscopy, and sphincter-preserving surgery where it matters most.
Bleeding and a change in bowel habit are too often dismissed as "just piles." A colonoscopy tells the difference quickly and confidently — and for colon or rectal cancer, catching it early is the single biggest factor in a good outcome.
Common symptoms to watch for
Bleeding or blood in stool
Change in bowel habits
A lump or prolapse at the anus
Unexplained weight loss
Persistent abdominal pain
Straining or constipation

How we treat Colon & Rectum conditions
Featured treatment
Colonoscopy
A camera examines the entire large intestine to investigate bleeding, change in bowel habit or pain, screen for cancer and remove polyps in the same sitting.

Frequently asked questions
No. Most piles improve with diet, fluids and minor office procedures. Surgery is reserved for advanced or persistent cases.
Pile bleeding is usually minor, but because bleeding can also signal colon or rectal cancer, it should always be assessed rather than assumed.
Modern laser and stapled techniques are far less painful than traditional surgery, and most patients return to routine within a few days.
A high-fibre diet, plenty of fluids, regular exercise and avoiding prolonged straining greatly reduce recurrence.
Cost depends on the grade of piles and technique used (banding vs laser vs stapled), so ask for a personalised estimate. Dr. Avinash Tank offers modern, low-pain piles surgery at Dwarika Hospital, Ahmedabad.
No. Piles are swollen blood vessels, whereas rectal prolapse is the full thickness of the rectum protruding — though they can look similar to patients and should be assessed by a specialist.
Laparoscopic repair is minimally invasive, restores normal anatomy and offers a faster recovery than traditional open surgery.
Many patients notice improved control once the rectum is secured, although recovery of full function can take time after long-standing prolapse.
A focused risk check based on Dr. Avinash Tank's published Colon Cancer and Rectal Cancer guides — not a diagnosis, and not a substitute for screening.
