Typical symptoms are localized hard lumps with glandular congestion and edema, and further localized partial lobular necrosis. Breast granulomatous mastitis is usually not self-curing, and its main treatment is through surgery, such as simple abscess incision, the scope of excision should completely remove the lesion to prevent recurrence.
