Hi,
Atypical Lobular hyperplasia is a precancerous condition that affects cells in the breast. Over the course of your lifetime if the atypical hyperplasia cells keep dividing and become more abnormal, your condition may be reclassified as carcinoma in SITU or noninvasive breast cancer.
If you are diagnosed with Atypical Lobular Hyperplasia, do what you can do to reduce your risk of developing breast cancer. Please be mindful that women between the ages of 45 to 55 with atypical hyperplasia have the highest risk. One never knows when cancer can develop….. For this reason doctors recommend close monitoring to determine if the cells are developing into a tumor, which happened in your case. When this happens, it is highly recommended to remove the growth through a wide local excision or lumpectomy (removal of the abnormal tissue along with the edges of the normal surrounding tissue).
If you are not sure on how to proceed, you could consult a Breast specialist for a second opinion.
For your information, be confident that an excisional biopsy will NOT spread abnormal or cancerous cells.
Take care..
