|LCIS - Lobular Carcinoma In Situ
Questions about lobular carcinoma in situ.

|6/19/2010||Hello. I am 52 years old and it's been 9 months since last period. I was just diagnosed with LCIS when calcifications were removed during stereotactic needle biopsy. Had bilateral MRI with and without contrast this week. Results: "no suspicious mass or enhancement seen in either breast. very mild patchy enhancement in upper outer left breast. only one 4 mm focus even reaches threshold for detectable enhancement by CADstream and has a slow benign continuous enhancement curve. A signal defect from a biopsy marking clip is seen in this region. There is no significant cyst formation. There is no lymphadenopathy. Impression: Mild patchy enhancement in the upper outer left breast, in the region of recent biopsy proven LCIS. This is the region that is to be surgically resected. Otherwise unremarkable exam."I have been advised to have an excisional biopsy, but some very reputable web sites (NIH, Mayo Clinic) don't advocate this approach as a matter of course. Are there breast changes that occur with menopause that may "resolve" on their own? Are there different "types" of LCIS (i.e., pleomorphic)that would indicate one course of treatment vs. another and, if so, can we tell the type from the stereotactic biopsy? I want to do the responsible thing but do not wish to have surgery if it is not necessary. Can you please comment? Thank you!|
