Causes Of Dilated Breast Ducts

Experts do not know cause of dilated breast duct yet. Breasts are composed of connective tissue. It involves milk ducts too, that are tiny, small tubes that carry milk to the nipples. In the event that milk duct below the nipple becomes dilated and plugged due to reasons like a fluid substance, dead skin cells etc. it results in dilated milk ducts.

There is an inflammation in the duct walls.

Some experts believe that the dilated breast duct may be caused due to some of the following factors-

Breasts undergo some changes over the period of aging process:

  • The breasts undergo involution which is a part of natural aging process
  • Milk ducts may get plugged and obstructed, causing the duct walls to get inflamed, during this phase, though the changes are quite normal otherwise


Those who are regular smokers, they have an increased risk of dilated milk ducts which may lead to infection, according to some studies

Inverted nipple:

Milk ducts can get blocked due to an inverted nipple. This may make the milk ducts dilated

An inverted nipple must be brought to an immediate attention of the physician, as it might be an indication of any other serious disorder
