In what cases do breast nodules or lumps need to be surgically removed? 1.Single solid nodule or mass larger than 1 cm in size. 2, Regardless of the size, single or multiple solid nodules or masses, ultrasound suggests irregular boundaries, strong echogenic calcification signs or abundant blood flow; mammography suggests burr signs or gravel-like calcification. 3.Long-term single or multiple small nodules or lumps with no change or shrinkage by conservative drug treatment, or increasing in size during treatment and with the above signs on examination. 4.Family history of breast cancer, long-term exposure to radiation in the chest, recent appearance of breast nodules or lumps after menopause; previous surgical treatment of breast cancer on the opposite side and now nodules appear in the breast, nodules or lumps appear again after removal of benign hyperplasia or fibroids in the breast; nodules or lumps with atypical hyperplasia on puncture examination. 5, There are more obvious nodules or lumps before preparing for pregnancy and delivery. 6.Single or multiple cysts of the breast exceeding 2-3 cm. 7. Small nodules or lumps under the areola found upon examination for nipple overflow. Indications for surgery for mastocytosis: (1) Those with more severe lesions, ineffective with long-term medication, and severe mental stress affecting work and life. (2) Those with severe lesions and a family history of breast cancer. (3) The lump becomes larger and harder during the follow-up process, and the former diffuse nodule becomes a limited isolated lump (4) Nipple discharge (especially bloody), and the presence of cancer is suspected. (5) Mammography suggestive of calcified spots, especially small sediment-like or pinpoint-like calcified foci (6) Puncture biopsy suggesting atypical hyperplasia of the breast epithelium. (7) Other reasons that cannot exclude breast cancer.
