LCIS diagnosis after 2nd surgery

brocade

Hi,

I have bilateral breast cancer.  I had surgery to remove invasive carcinoma on both sides with lymph node involvement on one side. I had 3 months of chemo and I had a second surgery 2 weeks ago to clean the margins on both sides and remove additional lymph nodes.  The margins were clear and the additional lymph nodes were clear.  But they found LCIS, which I know is pre-cancer.  I know that typically LCIS doesn't mean that one will develop invasive carcinoma, however, given the fact that I already had invasive carcinoma, I'm wondering if that increases my risk.  Does anyone have any info on this?  I will be starting radiation in a week and will be on tamoxifen after that.  Has anyone had a similar diagnosis?  Thank you.
