Since the 1970s, in order to protect the psychological and physiological health of breast cancer patients and improve their quality of life, the scope of surgical treatment of breast cancer tends to become smaller. At present, breast-conserving surgery plus sentinel lymph node biopsy has gradually replaced radical surgery as the standard procedure for patients with early breast cancer. Early breast cancer patients after breast-conserving surgery require postoperative adjuvant radiation therapy. In recent years, conformal intensity-modulated radiation therapy has gradually replaced tangential field irradiation as the main mode of adjuvant radiation therapy after breast-conserving surgery. Conformal intensity-modulated radiation therapy has better target area conformity and dose uniformity in the target area than ordinary tangential field radiation therapy, and can better protect important dangerous organs. Compared with conventional forward radiotherapy techniques, the advantages of intensity-modulated radiotherapy in reducing pelvic dose have been well studied, but in IMRT, the number of fields is different, and the dosimetric protection of pelvis and normal tissues is different.
