Why do I express milk when I'm not pregnant?

Some women often find some white substance secreted from their nipples when taking a bath. It looks like milk, but it is solidified. If you clean it on the first day, it will come out on its own on the second day. Many people worry that it is because their breasts have inflammation. In fact, it is the effect of endocrine hormones secreted by the body. So why do you squeeze out milk when you are not pregnant? The following is a detailed introduction.

Normal breasts can only secrete milk during pregnancy or lactation due to the effect of placental lactogens. However, if there is nipple discharge without pregnancy, pathological conditions should be considered. Does the discharge overflow spontaneously or after squeezing? The former is mostly pathological, and about 13% of breast cancer patients have a history of spontaneous discharge. Benign or physiological discharge is more common after squeezing.

In the non-pregnancy and non-lactation period, the discharge of fluid when the nipple is squeezed is called nipple discharge.

1. Mammary duct ectasia

2. Intraductal papilloma

3. Breast cystic hyperplasia

4. Breast cancer. In short, nipple discharge is an important breast symptom, 10% to 15% of which may be breast cancer. If symptoms occur, go to the hospital promptly for treatment and do a smear cytology examination of the discharge. The positive diagnostic rate of near-infrared breast scanning for ductal lesions in the areola area can reach 80% to 95%. B-ultrasound examination and mammography also have a considerable accuracy rate.

Under normal circumstances, women who are not pregnant or giving birth will not express breast milk. If milk is expressed, it is often abnormal. It is abnormal lactation and the phenomenon of milk overflow. Guidance:

This situation requires prompt inspection. There may be breast diseases, hyperprolactinemia, and endocrine disorders. Therefore, clinical examination is needed to confirm the disease and treat it.

Women have estrogen in their bodies, so as long as they have been pregnant before, or even if they have not been pregnant yet, they may still secrete a small amount of milk. It is not a big deal as long as there is no discomfort.
