After mastitis cephalosporin, if the hard lump is small, it can usually be eliminated by itself. If the hard lump is large and forms an abscess, treatment such as incision and drainage of the abscess or surgical excision is needed. It is recommended that the patient can choose the appropriate treatment method under the judgment of the doctor’s advice. Mastitis patients’ breasts then develop symptoms such as limited lumps and increased volume of the affected side of the breast. And with the development of the disease lumps will gradually become softer in a short period of time, forming abscesses. After cephalosporin injection, the inflammation gradually recovers, and if the lump is small, it can usually be absorbed on its own, but if the lump is large and cannot be absorbed on its own or develops into an abscess, surgical treatment is usually needed. For breastfeeding mastitis patients, abscess incision and drainage or minimally invasive treatment can be performed. For non-lactating mastitis, surgical excision is the mainstay, which can completely remove the diseased tissue and avoid recurrence. It is recommended that the patient can complete the relevant examination and decide whether to carry out surgical treatment under the judgment of the doctor.
