Abstract
Abstract Over the past decade, breast cancer radiotherapy has increasingly focused on techniques to improve treatment precision and limit toxicity. Surface guided radiotherapy and respiratory gating has allowed for improved cardiac sparing and the elimination of permanent skin tattoos in women receiving breast radiation, while rapid developments in the technological delivery of radiation via both volumetric arc therapy and proton beam radiation have shown promise in further improving target coverage and normal tissue sparing for breast cancer patients. Cutting edge innovations, including MR-guided radiotherapy and FLASH technology are now being explored as means to further improve treatment precision and decrease toxicity. The purpose of this talk is to highlight and discuss these advances in radiotherapy, review the existing evidence to support their use in the treatment of breast cancer, and detail specific patient populations that are most likely to benefit. Discussion will also focus on ongoing and future research aimed at improving our understanding and utilization of these novel advances in care. Citation Format: Melissa Mitchell.
