Hello! I have recently been diagnosed with ADH and FEA from a core needle biopsy sample that was ordered due to a suspicious grouping calcifications found on mammography. I understand that ADH is considered benign but also pre-malignant, so excisional biopsy will be next in the standard protocol of treatment to fully rule out DCIS or invasive cancer. My understanding is that if diagnosed with ADH, a woman has a 7% chance of developing breast cancer (either DCIS or invasive) within 5 years, and a 13% chance within 10 years. I'm trying to understand these numbers more accurately -- does anyone on this thread know if these statistics include women who have undergone the standard treatment -- excisional biopsy and then 20mg of tamoxifen for 5 years -- or does it include the entire population of women with ADH whether or not they have had treatment. I want to get an accurate understanding of how much standard treatment would reduce my risk of developing DCIS or invasive cancer.
