If the plasma mastitis is in the early stage of infection, the breast is only red, swollen and painful, it can be treated with local hot compresses and intravenous penicillin or cephalosporin antibiotics for anti-infection treatment; 2. When there is skin breakdown, local disinfection with vital iodine is available and rosmarinic acid ointment is applied to the breakdown; 3. If the infection is further aggravated, breast abscesses may appear, which is manifested as fluctuating masses palpated in the breast, then surgery should be performed in a timely manner, with abscess incision and drainage being the main surgical method; 4. If plasmacytosis is a chronic infectious lesion, manifested as breast abscesses and accompanied by skin sinus tract formation, mastectomy should be performed in a timely manner at a regular hospital. In daily life, you should wash your nipples in time to keep them clean, while taking a light diet and avoiding too much spicy, stimulating food.
