@southgawalker,
Have you already had a biopsy? If so, what were your doctor's recommendations?

Hello @southgawalker , I am going to go out on a limb and guess that LCIS is lobular carcinoma in situ? There are several conversations about lobular cancer in the breast cancer group. I would encourage you to ask this question on the page; lobular cancer, let’s support each other. It is so frightening to hear the word cancer, there are a bunch of folks there who have been there and done that. Here is a link.

Since you must have had a biopsy to get this diagnosis, did your doctor give you those choices? Have you thought about a second opinion to look for a consensus?

Hello, I am in the same shoe as you. My surgeon recommends taking tamoxifens 5mg daily and yearly mammogram. May I ask whether the surgery your doctor is recommending is lumpectomy or mastectomy?
