Because breast diseases are mainly breast tumors, including benign and malignant tumors, they can be detected by color ultrasound, mammography, MRI scan, and tumor marker tests. Benign tumors include breast fibroids, breast lipomas and mastocytosis. Malignant tumors specifically include breast sarcoma, and breast cancer. A common symptom of breast disease is a lump in the breast, which can be painful. Patients with breast hyperplasia also have a certain regularity of pain. In addition, patients with malignant tumors may also exhibit bloody nipple discharge and even abnormal changes in the skin of the breast.
