Medical Oncologist/Hematologist Dr. Ahmad Daniyal (Dan) Siddiqui has joined the Mass General Cancer Center at Cooley Dickinson Hospital as Medical Director of Medical Oncology.

Dr. Siddiqui comes to Cooley Dickinson Hospital from the Saint Vincent Cancer and Wellness Center in Worcester where he held the positions of Medical Director and Chief, Division of Hematology and Medical Oncology. In addition, Dr. Siddiqui is an Associate Professor of Medicine at the University of Massachusetts’ Chan Medical School in Worcester.

In his new role, Dr. Siddiqui will lead the center’s clinical care and operations, and will collaborate closely with physician colleagues at the Mass General Cancer Center in Boston.

“I am very pleased to join a distinguished community hospital that is part of a world-renowned academic medical center,” said Dr. Siddiqui. “I strongly believe that the future of cancer care involves expedited access to subspecialty cancer care. For patients, this means the connection to the Mass General Cancer Center provides the support and resources, in the form of second opinions and clinical trials, for example, that they may need for the best possible outcomes.”

Dr. Siddiqui treats a variety of cancers, including cancers of the skin, lung, breast, head and neck, gastrointestinal track, and prostate. He also treats benign and malignant cancers of the blood.

Asked about his care philosophy, Dr. Siddiqui says his work is grounded in his love of teaching and his commitment to educate his patients to the best of his ability.

“I am a big believer in communication,” he said, noting he is known for keeping a white board in an exam room so he can draw diagrams for patients to help them better understand their disease and treatment.

“When someone is diagnosed with cancer, they need good explanations about what is happening, so they are not in the dark,” he added. “A well-informed patient, plus a caring, competent, compassionate cancer care team equals the best outcomes for people going through cancer.”

Dr. Siddiqui earned his medical degree from Nishtar Medical College in Multan, Pakistan and completed residencies at New York Medical College, Nishtar Hospital, and the Pakistan Institute of Medical Sciences. He completed his fellowship at the UMass Chan Medical School. He is board certified by the American Board of Internal Medicine in both Medical Oncology and Hematology Oncology.

In his free time, Dr. Siddiqui enjoys spending time with his family as well as walking, hiking, and bicycling, and believes it is extremely important to stay active. He also writes poetry in his native language, Urdu/Hindi, and is fond of historical documentaries.
