If you become pregnant during plasma cell mastitis, it is recommended to continue the pregnancy until delivery. During pregnancy there may be progression of the lesion, increase in size of the lump, redness, swelling, pus and ulceration of the surface skin, which can be treated locally by a doctor. Small abscesses can be drained by making a small incision and will not affect the pregnancy. If you’re not able to breastfeed after delivery, it depends on the specific situation. Most of the time, the cause of plasma cell mastitis is due to nipple inversion and dilation of the large ducts, so it is often difficult to breastfeed, so it is necessary to inhibit milk secretion and remove the lesions after delivery, so it is important to carry out the surgery for the treatment.
