In general, the first month after breast cancer surgery should be a review, mainly to understand the status of the mastectomy after surgery. The next review is every three months, mainly in the first two years, because the probability of recurrence of breast cancer is higher in the first two years, so the number of review is set to every three months, so that the recurrence or metastasis can be detected and treated in time. Then, from the third year to the fifth year, the review is basically once every six months, and then once after five years, and more than five years is basically called clinical cure. Therefore, the review of breast cancer needs to be formulated according to the time after surgery.
