DCIS, Comedo Type, high nuclear grade

I had microcalcifications show up on my mammogram.  Never had a lump that could be felt.  Stereotactic Core Needle Biopsy was done and came back DCIS Comedo type high nuclear grade.  Since tumor could not be felt are my chances better.  Had mastectomy no word on final pathology.  Also had sentinel node biopsy.  Is surgeon just being cautious by doing the SNB or is there something else he is not telling me.  I am scared because everything I read on this Comedo type, high nuclear grade is not good.  Does this mean I am definitly going to get cancer or that my chances of getting it are higher?  Thank you!

Hi,

I had a similar situation to yours.  The SNB is usually done as a precaution, due to the DCIS being large in size.  DCIS is encapsulated within the milk ducts, and there are different types - Comedo happens to be the more aggressive type in that if any - it would spread more quickly than the other types.  Having said that it is a very early form of breast cancer, and is still classified as stage 0.  Your surgeon is just being cautious and that is a good thing.  From what I have researched, it is more common for the SN to come back negative than positive for infection with DCIS.

Let us know what the pathology indicates, in the mean time try to stay positive, and I know its hard but try not to worry.  Hope this helps.

God Bless
