Definition

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.

Causes

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.

Risk Factors

All women between puberty and menopause are at risk for this disease.

Symptoms

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

Diagnosis

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.

Treatment

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

Prevention

Fibrocystic disease can’t be prevented.
