Why is there discharge when squeezing the nipple?

We know that breast disease has been a common concern in recent years. For women, the incidence of various breast diseases is also high, so it has also received widespread attention. Some minor daily symptoms should not be taken lightly. What I want to discuss with you today is the problem of discharge when squeezing the nipple. So what disease could be causing it? Here are three possible situations:

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. There is a lump adhered to the skin in the areola area where discharge occurs, which is usually less than 3 cm in diameter. The axillary lymph nodes on the same side may be enlarged, soft, and tender. If infection occurs, the local area of ​​the lump will show signs of inflammation such as redness, swelling, heat and pain.

2. Intraductal papilloma: This disease is more common in people aged 40-50 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. The lumps are nodular and of varying sizes, tough but not hard, not adhered to the skin, and have unclear boundaries with surrounding tissues. The lumps may shrink after menstruation.

At this point, we recommend that our female friends pay more attention to and take care of their breast problems in daily life, and try to avoid using various breast skin care products and growth-promoting drugs containing chemical ingredients. Once you find that there is discharge when squeezing the nipple, especially when it occurs on one side, you should go to the hospital for examination in time to rule out the possibility of related diseases and detect problems early and deal with them early.
