Once the latex ducts are dilated, can it not go down?

Mammary duct ectasia

is a chronic breast disease. In most cases, it is caused by increased endocrine production in the mammary ducts and stimulation of the mammary ducts, causing them to dilate and overflow secretions. The disease may lead to changes in the structure and function of breast tissue, which are often difficult to reverse, so it is generally impossible to heal. However, if the disease is diagnosed and treated strictly, most patients can be completely cured.
