Back in 2006 or 2010 when I started to get a lot of atypical ductal hyperplasia my surgeon brought up the option of Tamoxifen. I chose not to because of the risk of blood clots. I've so far been managed okay with every 3 yr MRI, annual mammo and every 6 months ultrasound for 2-3 years. I had lumpectomies in 2006, 2010, and 2018 for papilloma, ADH, sclerosing scar. But I'm now in my 2nd year of abnormal MRI and mammo results on both breasts heading to two biopsies. I've done A LOT of research the last week. Do you know if you have the pleomorphic type of LCIS? That carries a higher risk for development of cancer.
