The glands in the breasts change during the menstrual cycle. They get bigger to get ready for a pregnancy. They shrink if pregnancy does not happen. This 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.
These harmless cysts can sometimes cause pain that happens late in each menstrual cycle.
A woman may have:
- Multiple cysts in both breasts that change with menstrual cycles
- Cysts that may or may not be painful and tender
No treatment is needed unless there is pain. Supportive care can help manage pain. This includes things like dietary changes, a supportive bra, or warm packs.
Other options are:
- Medicines, such as:
- Over the counter pain relievers like ibuprofen
- Medicine to balance hormone levels in the body
- Needle aspiration to remove fluid from the cyst
- Fine needle biopsy to remove tissue from the cyst
- Biopsy to remove the entire cyst
