Why does white fluid come out of the nipple?

I guess many female friends around us have had this trouble, that is, white liquid occasionally comes out of the nipples, but they are not breastfeeding and have not had an abortion, so they feel very nervous. Sometimes it may feel a bit embarrassing. Some women feel very shy, so they are unwilling to go to the hospital for examination, which eventually delays the treatment of the disease. So why do some women have white liquid squeezed out of their nipples during the non-breastfeeding period? Let me help you analyze this problem.

In the non-pregnancy and non-lactation period, the discharge of fluid when the nipple is squeezed is called nipple discharge. Nipple discharge is one of the common symptoms of breast disease. According to statistics, patients with nipple discharge as the primary symptom account for 3% to 14% of breast disease patients, and its incidence rate is second only to breast lumps and breast pain.

If the nipple discharge is from one nipple, it is usually related to the following breast diseases:

1. Mammary duct ectasia: For some patients with this disease, the first early symptom is nipple discharge. The color of the discharge is mostly brown, and a few are bloody; laboratory examination of the discharge shows a large number of plasma cells and lymphocytes but no tumor cells. This disease is more common in non-lactating or menopausal women over 40 years old.

2. Intraductal papilloma: This disease is more common in people aged 40 to 50 years old. 75% of the tumors occur in the area near the nipple. The tumor is very small, has a pedicle and villous, and has many thin-walled blood vessels, so it is easy to bleed. Laboratory examination can find tumor cells in the discharge. Sometimes, when patients carefully palpate their breasts, they may find a cherry-sized lump under the areola that is soft, smooth and movable.

3. Breast cystic hyperplasia: more common in women of childbearing age. The nipple discharge of some patients is yellow-green, brown, bloody or colorless serous, and laboratory tests show no tumor cells in the discharge. This disease has two characteristics: one is the manifestation of periodic breast pain, which often occurs or worsens before menstruation. Mild cases are usually not noticed by patients, but severe cases can affect work and life. Second, breast lumps are often multiple and can be seen on one side or both sides. They can also be limited to one part of the breast or dispersed throughout the breast.

Also, it is important to note: 1. Whether the discharge is true or false. A true discharge is fluid leaking from the milk ducts. Pseudodischarge is common in people with inverted nipples. It is caused by the accumulation of exfoliated cells of the nipple epidermis in the indentation, causing a small amount of liquid bean curd-like exudate, which often has a foul odor. Once the inverted nipple is pulled out and the area is kept clean, the "discharge" will disappear. 2. Is the discharge bilateral or unilateral? Bilateral discharge is physiological. For example, most women will still secrete a small amount of milk within one year after stopping breastfeeding.

According to the above introduction, we know that there are many reasons for the white liquid to be squeezed out of the nipples, so when female friends have such symptoms, don’t worry, and don’t be shy and don’t go to the hospital for examination. If such symptoms occur, you must go to the hospital for examination in time and confirm the cause of the white liquid to be squeezed out of the nipples with the help of a doctor.
