- Multiple lumps (cysts) will occur in both breasts that cycle with menstrual periods.
- Cysts may produce no symptoms or cause pain and tenderness.
- A fibrocystic lump may be difficult to tell apart from a cancerous mass. But, its rapid disappearance with menses and reappearance in the next menstrual cycle help to distinguish this condition from breast cancer.
- A fine needle biopsy is nearly identical to 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 a surgical incision. This can be done with local anesthesia if the lump is small and superficial.
