Stage II breast cancer is still relatively early. If a modified radical breast cancer surgery can be performed, followed by chemotherapy or endocrine therapy, the treatment effect will be very good, and the 5-year survival rate can basically reach about 90%. In other words, 90% or even more patients can live beyond 5 years, or even much longer than 5 years. The longer the time, the lower the probability of tumor recurrence and metastasis, so basically patients can live for a long time. For stage II breast cancer, modified radical breast cancer surgery is required, which means the entire breast is removed and the axillary lymph nodes are cleared at the same time. In general, there are fewer metastatic lymph nodes and they are not fused into a cluster. After surgery, you should come to the hospital for regular review and change the treatment plan if you find any recurrence or metastasis.
