I thought DCIS was contained. My cousin was told that she has DCIS with 1.65 mm micrometastasis in a node. How can it be in situ and in a node? And can you tell me what poorly differentiated means?
I was diagnosed with breast cancer about 2 years ago, but mine was IDC.
Thank you

Cindy, are you sure they told her DCIS? Because "ductal carcinoma with apocrine differentiation and micrometastasis" doesn't say DCIS to me, it says IDC. Poorly differentiated is one of the factors used to determine tumor grade. It refers to the ability of the cancer cells to build breast tissue like normal cells do. Cancer cells that aren’t very aggressive act “normal” enough to do this. Cancer cells that are aggressive and growing quickly (poorly differentiated) lose their ability to build breast tissue; they’re just too wild. I hope this helps - PJH
