Patients undergoing breast cancer surgery are usually hospitalized for about 1-2 weeks, but of course, it needs to be judged in conjunction with the overall recovery of the patient. Basically, breast cancer surgery is mainly a modified radical breast cancer surgery, but of course there are some breast-conserving surgery, or mastectomy, or sentinel lymph node dissection surgery, etc. The details are as follows: 1. The larger the scope of surgery, the more traumatic it is for the patient, the longer the recovery time, and the hospitalization time may be extended, for example, around 1-2 weeks, especially if some complications occur. 2. The smaller the scope of surgery, the faster the patient’s recovery and the shorter the hospital stay, and the patient may be discharged within 1 week after surgery, or even within 4-5 days.
