PATHOLOGY

Detailed explanation-1: -Lactation begins as early as a few weeks into the second trimester of your pregnancy. As estrogen and progesterone levels rise, your body prepares for lactation by increasing the number of milk ducts in your breasts, and those milk ducts will transport milk from the alveoli to your nipples.

Detailed explanation-2: -Lactation is common after a woman has given birth, and it can sometimes occur during pregnancy too. However, it is possible for both women and men to produce a milky discharge from one or both nipples without being pregnant or breastfeeding. This form of lactation is called galactorrhea.

Detailed explanation-3: -Reasons for lactating when not recently pregnant can range from hormone imbalances to medication side effects to other health conditions. The most common cause of breast milk production is an elevation of a hormone produced in the brain called prolactin.
