Mammogram shows an asymmetric gland in the upper quadrant of the left breast with slightly rough edges, which may be a breast nodule, and malignancy cannot be ruled out because of the slightly rough edges of the gland. If it is a breast nodule, for benign and small breast hyperplasia, you can take hormones, iodine preparation and other drugs, and the drugs must be used under the guidance of a doctor. For larger, fast-growing benign nodules, they can be surgically removed by a doctor according to the patient’s condition. If the gland is at risk of becoming cancerous, patients are advised to undergo further breast histopathology to confirm the diagnosis. Radiotherapy, chemotherapy, mastectomy, etc. will be chosen according to the severity and spread of the breast cancer. The patient’s mammogram shows an asymmetric gland with slightly hairy edges in the upper quadrant of the left breast.
