Progress of clinical study on hypofractionated radiotherapy after breast-conserving surgery.

Whole-breast radiotherapy after breast-conserving surgery (BCS) can improve patient survival while reducing local tumor recurrence. Although standard breast radiotherapy can achieve good tumor control and cosmetic effects with low toxicity, the 5- to 7-week treatment time is relatively long for patients and can result in wasted medical resources. Therefore, there is a growing trend toward hypofractionated radiotherapy (HFRT), which accelerates partial-breast irradiation.
