Epithileal Hyperplaysia

[bs883]

My sister recently had a biopsy and the results were epithileal hyperplaysia, what is this and what does it mean.

The reason for my concern is that I had DCIS/Comedo/type 3, and had a mastectomy about 6 months before her diagnosis.

Thank you

Dear BS883:  Atypical hyperplasia indicates that there are cells within the ducts that have developed changes inconsistent with normal tissue growth.  These are not technically malignant.  The concern is that if this were to go unchecked, these cells may develop cancerous changes.  The usual progression is thought to be atypical hyperplasia, DCIS, invasive ductal carcinoma.  Of course, the length of time it takes for cells to mutate from one thing to another is largely unknown and most likely varies from person to person.   Usually, the recommendation might be more frequent mammography (every 6 months).  Depending on the individual, the doctor may also recommend avoiding hormone replacement therapy.
