Since the diagnosis of breast cancer has been confirmed, it means that the breast lump was reported as grade 4B on ultrasound, but a puncture biopsy has been performed to confirm the diagnosis of breast cancer. Whether or not breast cancer can be cured depends on the size of the lump and whether or not there are any lymph node metastases. If the lump is relatively small, such as a tumor within 2cm, and there is no lymph node metastasis, not to mention distant metastasis, it can be cured by modified radical surgery or breast-conserving surgery, and the 5-year survival rate of the patients after the surgery is more than 85%-90%. So, although the lump in the breast is grade 4B, as long as the tumor is small enough and there is no lymph node metastasis it can be cured. If the lymph node metastasis is more, combined with distant metastasis can not be cured, only through chemotherapy, endocrine therapy, targeted therapy, etc. to reduce pain and prolong life.
