If parastomal breast is found during breastfeeding, it is considered to be a result of hormonal changes in the body during breastfeeding, leading to an increase in the size of the parastomal breast. Parametrial breast disease is caused by congenital developmental abnormalities and is not suitable for surgery during breastfeeding. The choice of surgical solution and anesthesia is based on the size of the lesion. During breastfeeding, it is also important to observe changes in the signs and symptoms of the parametrium and not to eat irritating foods, as there are certain triggers for the occurrence of parametrium. During pregnancy, breastfeeding, and childbirth, the size of the parametrial breast can increase, and some patients may even show the presence of parametrial nipples, which can be characterized by changes in the local nipple overflow. The most effective treatment for this disease is surgery, which also requires a pathological examination.
