The white stuff that can be squeezed out of the breast may be a small amount of milk or secretion from the breast ducts. During non-lactation or early pregnancy, breast tissue may also secrete a small amount of milk, which is a normal physiological phenomenon, probably due to early pregnancy, around menstruation or changes in hormone levels during ovulation, resulting in breast tissue producing milk, usually in small amounts. If the nipples secrete pale blood or other colored discharge, there is a possibility of malignant lesions, and it is recommended to do breast ultrasound or mammogram to clarify the cause. It is also recommended to apply roxithromycin ointment to the nipples, pay more attention to washing the breasts, keep them dry and clean, and eat light food.
