Breast Surgeon Jesse T. Casaubon, D.O., Joins the Department of Surgical Oncology at Baystate Health

SPRINGFIELD – Breast surgeon Jesse T. Casaubon, D.O., who recently completed training in breast surgical oncology, has joined the Department of Surgical Oncology at Baystate Health.


“I was inspired by my physician grandfather, who worked so hard for his community. I heard so many stories about him and I remember wanting to impact the community the way he could,” said Dr. Casaubon.


Dr. Casaubon earned his bachelor of science in Health and Exercise Science with a concentration in Sports Medicine and a minor in Biomedical Science at Colorado State University, before going on to earn his medical degree at Rocky Vista University College of Osteopathic Medicine in Parker, CO.


He completed his medical residency in general surgery at New York Medical College, Wyckoff Heights Medical Center, followed by a fellowship in breast surgical oncology at Alpert Medical Center, Brown University – Women & Infants Hospital in Providence, RI.


“Breast Surgery is an incredible field where the surgeon, in combination with the multidisciplinary team, is able to offer patients excellent outcomes and survival. It is a field where the physician can form lasting relationships with patients. It is a field that is driven by research, but has many unanswered questions that offer the opportunity for further research,” said Dr. Casaubon.


Active in the area of research, Dr. Casaubon is currently involved in studying COVID-19 related delays on the upgrade rates of atypical ductal hyperplasia. He recently published “Breast specific sensuality and appearance satisfaction: A comparison of present breast conserving surgery and nipple sparing mastectomy” in the Journal of the American College of Surgeons.



Dr. Casaubon is board certified by the American Osteopathic Board of Surgery.


He is a member of several professional organizations, including the Society of Surgical Oncology, American Society of Breast Surgeons, and DOCARE International.


Dr. Casaubon has an interest in oncoplastics.


“Oncoplastics is the new standard of care for women. While the main focus of what we do is eradicating the cancer, there is no reason why women should be permanent deformity. Oncoplasty is applying advanced surgical techniques to offer patients excellent aesthetic outcomes,” said Dr Casaubon.


Among his many honors and awards, Dr. Casaubon was awarded First Place in the Scientific  Writing and Research Competition at Wyckoff Heights Medical Center, Global Medicine Honors Award from Rocky Vista University for his dedication and participation in global medical outreach.


Dr. Casaubon has brought his experience and talent to other countries to treat those in need including work at the Hopital Sacre Coeur in Milot, Haiti, where he provided general, trauma and pediatric surgery through the CRUDEM Foundation and the Oversees Medical Assistance Team (OMAT), and at Nicaragua Rural Ambulatory Care Clinics in Leon, Nicaragua through Health Outreach for Latin America.  He also opted for several foreign clinical rotations during his residency including a primary care elective rotation in Lilongwe, Malawi; a Spanish medical rotation in San Isidro, Costa Rica; and a Nepal global medicine elective rotation in Kumari/Kathmandu, Nepal.


“Working in other countries provides the opportunity to understand how medicine works elsewhere. Both the good and the bad. Many of the high-tech equipment and medications are not available, but it is incredible to learn how to be effective with limited resources. I think that is hugely important as an increased reliance on technology can set you up for difficulties if that technology breaks down,” said Dr. Casaubon.


Outside of the hospital, Dr. Casaubon keeps fit by participating in marathons, sailing and scuba diving. He recently placed 5th for age and 26th overall in the Lost Cat 50k Ultramarathon last August. He also completed four marathons during residency training including the New York City, Brooklyn, and Denver Marathons, as well as numerous half marathons during that time. As part of being out on the sea, Dr. Casaubon is certified by the American Sailing Association in bareboat charter, coastal cruising and basic keelboat operation, and is certified by Professional Association of Diving instructors (PADI) in enriched air (NITROX) and advanced open water scuba diving. An amateur photographer whose works have been shown, Dr. Casaubon’s interest in the hobby dates back to high school.


“I like staying healthy, doing fun outdoor things, and every once in a while a challenge when I’m not at work,” he said.


His message to women during Breast Cancer Awareness Month – “Mammograms save lives.”


Dr. Casaubon is accepting new patients and virtual visits are available. He is currently seeing patients in Springfield, Northampton, and Greenfield.
