Yellow fluid in breast

When a woman becomes pregnant, her breasts will undergo obvious changes, and fluid may even flow out of the breasts in the late stages of pregnancy. This is because the level of prolactin in the body increases after a woman becomes pregnant. However, if you are not pregnant or breastfeeding, and yellow fluid is flowing out of your breasts, you need to go to the hospital for examination and treatment. Sometimes this situation is caused by some diseases.

Case 1

Generally speaking, if nipple discharge occurs on both sides, it may be a physiological or systemic disease. For example, when a newborn is born, the level of estrogen brought from the mother's blood is high, and a small amount of milk may be secreted within 1 to 2 weeks after birth. Galactorrhea-amenorrhea syndrome caused by hypothalamic-pituitary lesions in adults, etc.

Case 2

If the nipple discharge is unilateral, it may be a pathological change, and is mostly a local lesion, such as benign mammary duct lesions and breast cancer.

Case 3

If it is a multi-porous discharge (carefully observe whether the discharge is from one point or multiple points), it can be seen in physiological cases, and can also be seen in cases with a larger range of lesions, such as mammary duct dilatation syndrome, breast hyperplasia, etc.

Case 4

If the discharge is from a single hole, it may be caused by lesions in a certain duct, such as intraductal papilloma, intraductal papillary carcinoma, etc.

Don't always stimulate or squeeze it. If there is a problem, squeezing will cause the bacteria to flow back into the mammary ducts.

Case 5

If the overflow occurs spontaneously, it usually means that there is a large amount of fluid accumulated in the catheter and it is still being secreted, and it is likely to be a pathological overflow with a large range. If the overflow is caused by squeezing, it means that there is less fluid accumulated in the catheter. The overflow after squeezing a certain part often indicates that the part may be the location of the lesion.

Case 6

Careful observation and identification of the characteristics of nipple discharge is of great significance in finding the cause of the discharge. Generally speaking, milky discharge often manifests as spontaneous bilateral multi-porous discharge during the non-lactation period. Its color and properties are like skim milk. It is mostly caused by hypothalamic dysfunction and abnormally elevated prolactin levels in the blood.

Situation 7

Serous discharge is often squeezed out, and a few cases are spontaneously discharged, often wetting clothes. It can occur on one side or both sides. The discharge is thin, transparent, slightly yellow or brown or viscous. It is mostly caused by benign breast diseases, such as fibrocystic fibrosis, mammary duct ectasia syndrome and intraductal papilloma. A few cases of serous discharge can be caused by breast cancer.

Case 8

Watery discharge is often unilateral and is thin, colorless, and like clear water. It is often caused by tumors. Some breast experts often say that about 50% of watery discharge may be caused by cancer.

Case 9

Purulent discharge often occurs unilaterally, overflowing on its own or being squeezed out. It is mostly green or milky yellow, thick, pus-like, and may contain blood. It is more common in inflammatory breast diseases, such as mammary duct ectasia syndrome.

Situation 10

Bloody discharge often occurs unilaterally, overflowing on its own or being squeezed out. The discharge is bright red, light red, light brown or coffee-colored. It is mostly caused by intraductal papilloma, and can also be seen in breast cancer, fibrocystic fibrosis or mammary duct ectasia syndrome.

Since malignant lesions are more likely to cause bloody discharge, clinically patients with bloody discharge should be more alert to the possibility of malignant lesions.
