There is no pain associated with mammography. Anesthetics such as lidocaine are usually injected before the examination. For patients with breast tenderness and lumps and nipple overflow, mammography can be done. Before the lactoscopy, you should prepare for the procedure by cleaning your breasts and nipples, choosing the right underwear, relaxing as much as possible during the procedure and cooperating with the doctor’s requirements. After the procedure, you should rest for half an hour before leaving, pay attention to whether there is any overflow from the nipple and other adverse reactions, keep the nipple area dry and clean to avoid causing infection, and avoid eating spicy and stimulating foods.
