Not necessarily. Both lactational mastitis and plasmacytic mastitis can present with the stage of breast abscess. Conventional treatment, which requires incision and drainage, is invasive and requires some time to change the medication after incision, with exudation from the wound cavity, which affects the quality of life. For conservative treatment, puncture and extraction of pus can be tried. However, depending on the amount of abscess, more than two or even several puncture aspirations are required. Advantages: minimal trauma, aesthetics, no or small scarring, and good quality of life. Especially, for patients with breastfeeding mastitis, there is a chance to continue breastfeeding, which benefits both the baby and the mother’s breast health. In addition, for patients with a small number of breast abscesses, treatment with herbal medicine can sometimes lead to abscess absorption and avoid the pain of incision. Of course, there are very few cases of abscesses where the pus is too thick and the pus does not come out through puncture. In this case, incision and drainage are still needed.
