A portion of benign breast tumors can be minimally removed (minimally invasive resection here refers to minimally invasive atherectomy of the tumor, excluding mammoscopic surgery).

First of all, it needs to be clarified that if the pathological confirmation of the breast tumor is malignant, minimally invasive rotary resection surgery cannot be performed.
Whether benign breast tumors can be minimally invasive atherectomy depends on two aspects, one is the type of benign tumor, and the other is the size of the benign tumor. Common pathological types of benign breast tumors include breast fibroadenoma, ductal papilloma, and phyllodes tumor. Among them, the characteristics of phyllodes tumors are that if the resection range is insufficient, it is easy to postoperatively, and with the increase of the number of times, it will gradually develop into borderline, even malignant phyllodes tumors, so if there is a preoperative needle biopsy pathology confirmed as a phyllodes tumor, it is not suitable for minimally invasive rotary resection. Some ductal papillomas are accompanied by nipple discharge, and color ultrasound will indicate that the tumor is connected to the dilated duct, which needs to be removed together with the discharge duct, so it is not suitable for minimally invasive rotary resection; In the case of no preoperative needle biopsy pathologically confirmed as ductal papilloma, it is not impossible to perform minimally invasive atherectomy because the doctor cannot foresee the pathological diagnosis, but if the postoperative pathology confirms that the ductal papilloma is confirmed, regular postoperative reexamination is required. In general, fibroadenomas smaller than 2 cm can be minimally invasive rotary resection, but for fibroadenomas larger than 3 cm, minimally invasive atherectomy is generally not considered.
