co-leads the Gastrointestinal Cancers Disease Oriented Team at Simmons Cancer
Center. He is a member of the ECOG-ACRIN Cancer Research Group’s Gastrointestinal
Cancer Core Committee, where he leads the Pancreatic-Hepatobiliary Cancers working
group. He is also a member of the National Cancer Institute (NCI) GI Cancer
Steering Committee’s Pancreatic Cancer task force. Additionally, he is leading
multiple trials on drug combinations in our labs at UT Southwestern, which have
been found to have promise.
Prior to joining joined UT Southwestern in 2011, Dr. Beg attended medical school at Aga Khan University in Karachi, Pakistan, where he graduated with honors. He completed his residency in internal medicine and a fellowship in hematology/oncology at the University of Cincinnati.
Dr. Beg is board certified in hematology and medical
oncology, and he is a member of the American Association for Cancer Research
and the American Society of Clinical Oncology.
His research has been featured in national and international
cancer meetings, and he has published articles in many peer-reviewed medical
publications. Dr. Beg is often invited to give lectures on pancreatic cancer
treatments and health information technology, and he is a reviewer for multiple

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
