M Altan Kaya

Dr. M Altan Kaya is a general surgeon specializing in minimally invasive surgery for obesity and breast cancer. He is a member of the European Society of Oncological Surgeons. The specialist has performed hundreds of bariatric and oncological procedures at Risus Clinic Istanbul.

Specialization & Approach

Dr. Kaya treats patients with obesity using gastric bypass, gastric sleeve, and gastric balloon techniques. He also performs metabolic surgery and endoscopic sleeve gastroplasty (ESG) — a procedure that reduces stomach size using an endoscope. For oncology patients, he performs breast cancer surgery and colorectal tumor removal. He also performs hemorrhoidectomy for the treatment of swollen veins in the rectum.

He uses minimally invasive methods to reduce recovery time and post-operative pain. This approach lets patients return to normal activities sooner because the incisions are smaller.
