Agalactia is secondary and occurs much less frequently than primary. Its occurrence is explained by various chest injuries, including surgery or broken ribs. If we are talking about this form of the disease, then the disease primarily affects the upper layers of subcutaneous fat, and in some cases the skin tissue. As a result, the breasts become wrinkled and flat, as if there is no fat layer under the sternum, which makes them look like a bag. The woman also develops a feeling of heaviness that does not disappear even after breastfeeding the baby, which makes the pain during feeding become unbearable. When trying to touch the nipples, owners of this disease also experience pain or discomfort. The disease is considered incurable and goes away on its own over time, but it should be understood that a woman will not be able to breastfeed her child, so it is better to immediately resort to medication rather than wait for a natural recovery.
