Breast granuloma is generally referred to as granulomatous mastitis, a non-caseous necrotic, granulomatous lesion of the breast that is confined to the lobules. Signs of improvement in granulomatous mastitis are manifested by a softening or disappearance of the lump and a reduction in pain. Most cases of granulomatous mastitis are caused by infection, trauma, milk accumulation, chemical irritation, etc. Granulomatous mastitis is a chronic inflammatory disease of the breast that is characterized by the shape of granulomas in the breast tissue as the main pathological manifestation. It mostly shows a lump in the breast with a hard texture and is accompanied by pain and swelling. After treatment with medication or surgery, signs such as the gradual softening or disappearance of the breast lump and a decrease in breast pain indicate that the condition is improving. During the treatment period, it is necessary to pay attention to a light diet, avoid breast trauma or chemical stimulation, so as not to aggravate the condition, and if there are uncomfortable symptoms, it is recommended to consult a doctor in a timely manner.
