A core needle biopsy may be done to get a definite diagnosis. Women in their teens or early 20s may not need a biopsy if the lump goes away on its own or if the lump does not change over a long period of time.

If a biopsy shows that the lump is a fibroadenoma, the lump may be left in place or removed.
The decision to remove the lump is made by the patient and the surgeon. Reasons to have it removed include:
Abnormal biopsy results
Pain or other symptoms occur
Worry or concern about cancer
If the lump is not removed, your health care provider will watch to see if it changes or grows. This may be done using
Sometimes, the lump may be destroyed without removing it, using freezing. This is called cryoablation.
Women with fibroadenoma have a slightly higher risk of breast cancer later in life. Lumps that are not removed should be checked regularly by physical exams and imaging tests, following the doctor's recommendations.
If the lump is left in place and carefully watched, it may need to be removed at a later time if it changes or grows.
In very rare cases, the lump may be cancer. You may need further treatment.
Calling your health care provider
Call your health care provider if you have a lump that is thought to be a fibroadenoma and it grows or changes in any way.
