Bone marrow transplant study finds breast cancer risk in young women who received total body irradiation
A new study examining long-term outcomes of blood or marrow transplantation (BMT) found that patients who received total body irradiation (TBI) at age 30 or younger had a 4.5-fold increase in their risk of developing breast cancer later in life compared with the general population. The research, published in the Journal of Clinical Oncology on July 16, 2020, also found increased risk of breast cancer among women exposed to alkylating agents and anthracyclines as part of BMT.
