Fibrocystic disease occurs when there are fluid-filled cystic lumps of duct tissue. These lumps are surrounded by a scar-like capsule of tissue in the breasts.

The glandular tissue of the breasts cycles monthly with menstrual periods. It enlarges to prepare for a pregnancy, and then shrinks if one does not occur.

However, most women will not seek treatment.
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include the following:

There are two types of biopsies:
Once cancer has been ruled out, fibrocystic disease may be safely treated with observation and conservative measures, including:
