breast biopsy result shows duct epithelial hyperplasia

Hi, I am assuming that this is taken from breast. If it is not, the following post would not apply. Epithelial hyperplasias are common. They indicate proliferation of breast tissue, this is fine for as long as it is NOT marked with atypia (if it was the report would read atypical ductal hyperplasia). Atypical hyperplasia would have an increased risk for developing cancer. The key word atypical would also distinguish increased risk for columnar metaplasia. Adenosis is likewise benign and no clear association with breast cancer exists with cystic dilatation of the ducts. The actual impact of microcalcifications and stromal fibrosis on risk is difficult to estimate as their presence usually triggers the biopsy (so a lot of women may receive a diagnosis of invasive or pre-invasive breast cancer along with these findings). What is clear is that their importance is due to the association, so what the pathologist really looks for is the presence of cancer along with these findings. If these are absent in your report, then well and good. Overall, there seems to be no reason to worry with the above items.
