@bestpommom First let me say I am so sorry to hear that you are having to deal with all of this. ADH alone does not necessarily need to come out. Although some recommend it comes out because if it is found on a biopsy DCIS can still be hiding so they will recommend taking the whole thing out so they can make sure there is nothing else. Other clinics will take the watch and wait approach. It is completely up to you though on what you feel comfortable doing. If they sent the biopsy away for a second opinion I would wait for that opinion and see what that comes back with. Usually with ADH radiation is not involved only surgery if that is what you chose as ADH is not cancer. If it is DCIS then yes you would want to remove it and do radiation. Will you be doing Chemotherapy also for the IDC or not? What kind of monitoring will they be doing after to make sure nothing comes back? Will you be on any Aromatase inhibitors post radiation/surgery? Hugs to you!
