The size of the breast nodule is not the only criterion for surgery, but whether it causes significant pain or malignancy, as follows: 1, no surgery: if the breast nodule is small and not considered malignant, then no surgery is needed, you can go to the hospital for regular review, if necessary, you can also take oral Chinese medicine for treatment, such as breast fetish elimination or prolotherapy pills, etc. 2, need to do surgery: if the breast nodule is relatively small and cannot be ruled out as malignant, then you need to improve the relevant examination, and later give regular drug changes. If the nodule is large and malignancy cannot be ruled out, it is necessary to improve the relevant examination and undergo surgery under anesthesia to remove it, and then give regular medication changes later. If the nodule is considered malignant after imaging and pathological biopsy, even if the nodule is small, radical excision of the tumor should be performed as soon as possible, followed by lymph node dissection and chemotherapy, targeted drug therapy, endocrine therapy and traditional Chinese medicine.
