Galactorrhea – pathological discharge by the mammary glands of milk, colostrum when pressed, not associated with the process of feeding the baby. The disease can be caused by hormonal disorders, benign pituitary tumors, dysfunctions of the hypothalamus and thyroid gland..

Milk duct ectasia represents pathological changes in the milk channels of the breast. The disease can be recognized by seals in the chest area, a nipple that becomes retracted with thick, clammy, dark discharge. Usually older women are affected by ectasia..

Intraductal papilloma – A benign neoplasm that develops in the milk ducts, accompanied by abundant transparent, pink or greenish discharge. This disease is also observed in older women..

Brown discharge – can be caused by bleeding in the milk ducts, as well as the development of mastopathy and malignant tumors. As a rule, dark and in some cases black color is caused by the presence of blood.

Bloody issues – One of the most serious, which can talk about the development of a malignant tumor or intraductal papilloma. Also, strong or smeared blood-red discharge may appear due to chest injury..
