Patients will undergo a breast biopsy at which the area found to be ALH or LCIS on core biopsy will be removed surgically through a small incision in the breast.
* The surgical biopsy specimen will be carefully examined by a pathologist, and may be useful in guiding further therapy if needed.
* In the future, tissue from the surgical biopsy may be used to study genetic changes that may be responsible for cancer formation and prevention. The tissue will be kept for future research for up to 10 years.
