Dr. Robin Mendelsohn is a gastroenterologist who focuses on taking care of gastrointestinal issues in people with cancer. She has a particular interest in working with people who are at high risk for developing colon cancer and rectal cancer because of hereditary conditions, such as Lynch syndrome, as well as those with young onset colon and rectal cancers. She also provides specialized nutrition support for people with cancer.

She has expertise in performing a variety of gastrointestinal endoscopic procedures, including colonoscopy and upper gastrointestinal endoscopy. She also is skilled at performing advanced endoscopic techniques, such as complex polypectomies and direct percutaneous endoscopic jejunostomies (placing a feeding tube directly in the small intestine). Cancer can sometimes create obstacles to daily activities, such as eating, and many of the procedures Dr. Mendelsohn performs help patients feel better by taking care of these quality of life needs for them.

In recent years, Dr. Mendelsohn and her MSK team have been able to reduce colon cancer rates because more people are getting screened appropriately. Though this is important progress, they have begun to see an increase in the number of younger people being diagnosed with this disease. Her research aims to find out why this number is rising. Dr. Mendelsohn is also investigating how best to care for younger people with colon cancer to ensure and address their specific long-term concerns and future goals.
