https://www.medscape.com/viewarticle/can-concurrent-boost-safely-shorten-breast-cancer-radiation-2026a1000fzs Concurrent radiation dose escalation to the lumpectomy cavity during whole-breast irradiation (WBI) demonstrated noninferior ipsilateral breast recurrence (IBR) compared with sequential boost in patients with high-risk early-stage breast cancer, while reducing overall treatment time from more than 4 weeks to 3 weeks. At 7-year follow-up, IBR was 2.2% with sequential boost and 2.6% with concurrent boost, with no differences in toxicity or cosmetic outcomes between approaches.
