The phenomenon of hard lumps and pain in the breast is relatively common in clinical practice, and the specific causes generally include the following: 1) inflammatory lumps, such as chronic mastitis and plasmacytoid mastitis, which can be relieved by anti-inflammatory and symptomatic treatment or local heat application. 2) common benign tumors, such as fibroids or lipomas in the breast, can cause painful lumps, which can be clearly detected by ultrasound. 3. The more important issue is that for senior women with hard lumps and pain in the breast, malignant tumors cannot be excluded, and the common ones are breast cancer, which is not particularly painful and occurs mostly in the outer upper quadrant of the breast, and has a higher chance of occurrence or cancer. Therefore, it is important to go to the hospital as early as possible for a systematic and standardized examination to find the appropriate cause of breast cancer and to provide systematic and standardized treatment according to the cause.
