The glands in the breasts change throughout the monthly cycle. They get bigger to get ready for a pregnancy. They shrink if pregnancy does not happen. This cycling causes cysts and fibrous tissue to build up. All women will have some form of this problem during their reproductive years. Most women will not seek medical care.
No treatment is needed unless there is pain. Choices are:
- Supportive care, such as dietary changes, a supportive bra, or warm packs
- Medicines, such as:
- Over the counter pain relievers like ibuprofen
- Hormone medicines for severe symptoms
- Needle aspiration to remove fluid from the cyst
- Fine needle biopsy to remove tissue from the lump
- Biopsy to remove the entire lump
