Meet Dr. Beg

Medical Oncologist and GI Cancer Specialist

In the fight against gastrointestinal cancers, Muhammad Shaalan Beg, M.D., is leading the charge.

"I spend a lot of time trying to understand what my patients' needs and expectations are, and what they want me to help them achieve. Is it to continue being able to work their current job, keep playing the piano, or attend a grandchild's graduation party? I need to understand where my patient is coming from."

As a medical oncologist at UT Southwestern Medical Center’s Simmons Cancer Center, Dr. Beg treats patients with pancreatic, liver, colorectal, and stomach cancer, as well as rare cancers such as neuroendocrine tumors and gastrointestinal stromal tumors (GIST). He is also Associate Professor of Hematology and Medical Oncology and is co-Leader of the Gastrointestinal Cancer Multidisciplinary team.

Dr. Beg is very active in clinical research including leading clinical trials at the Simmons Cancer Center, where he is bringing promising basic science discoveries from the lab to the clinic to better care for his patients.

He believes that GI cancers are best treated by a group of doctors. GI cancer patients are a very special and diverse group with specific needs, so Dr. Beg spends a lot of time getting to know his patients to assess their needs and expectations for cancer care. He believes in offering the best, personalized care available, which includes cutting-edge medical care, clinical trials, and innovations in surgery.

“We need to provide patients with more opportunities, and the best way to do that is through clinical trials,” Dr. Beg says. “My goal is to bring ideas from the lab and see how we can apply that to the clinic. We always think of clinical trials as something we are investing our time and money in, but if it’s not helping the patient, it’s not really a benefit at all.”
