Breasts are made up of ducts, milk glands, and fatty and fibrous tissues. Fibrocystic disease is when there are fluid-filled lumps (cysts) of duct tissue. These lumps are surrounded by a scar-like capsule of tissue in the breasts.

The glands in the breasts change throughout the monthly cycle. They get bigger to get ready for a pregnancy. They shrink if one does not happen. This cycling causes cysts and fibrous tissue to build up. All women will have some form of this condition during their reproductive years. Most women will not seek medical care.
These harmless lumps can sometimes cause pain that happens late in each menstrual cycle.
You may have:
- Multiple cysts in both breasts that change with menstrual cycles
- Cysts that may or may not be painful and tender
You will be asked about your symptoms and health history. A physical exam will be done.
Pictures may be taken of your breasts. This can be done with a mammogram .
It can be hard to tell the difference between this disease and breast cancer .
No treatment is needed unless you have pain.
Fibrocystic disease may be safely treated with:
- Over the counter pain relievers
- Hormone medicines for severe cases
- Warm packs
- Wearing a supportive bra
- Dietary changes, such as not drinking caffeine products.
Treatment may also include:
- Needle aspiration—If the fluid is removed, the cyst usually goes away.
- Biopsy (removal) of the suspicious area
After numbing the area, a small needle is inserted into the cyst. This is to draw fluid out.
There are two types:
- A fine needle biopsy is like an aspiration. The only difference is that a tiny piece of tissue is also drawn out of the lump.
- An excisional biopsy removes the entire lump through an incision. This can be done with local anesthesia if the lump is small.
