Dcis 2 sites and sentinel node bx

[Joyful_jr]

Hi,
I had a single cluster of microcalcification on screening mammo. During the biopsy, they discovered a second site of microcalcifications near the first.  Biopsies diagnosis on both locations were DCIS (hormone receptor positive). Breast surgeon said she is considering the 2 sites as one since they are near each other.   Having  surgery tomorrow for partial mastectomy and bilateral reduction.  This was by choice to go beyond lumpectomy to ensure clear margins as I have always pondered a reduction. My surgeon said she didn't think I needed a lymph node biopsy and was not planning on doing one . My PCM is concerned that I am no having a mastectomy or lymph bx since there were 2 sites if dcis. So my questions are:  is 2 sites more at risk?  Should I request a lymph node bx?  Thank you.

Thank you. My surgeon has been doing this for many years and has a great reputation. The biopsy was done at a breast care center that does so many that I feel confident in the results. I thank you so much for your response  and reassurance.

Hi,
I think your Surgeon is right not to consider biopsying the sentinel lymph node. DCIS is the earliest form of breast cancer and the cells are contained within the walls of the milk duct,they have not broken through the wall of the duct or have access to the blood stream or the “lymph nodes”.  In other words they have no ability to spread to other parts of the body.
In my opinion having 2 sites of calcification near each other wouldn’t put you at a higher risk because both can be successfully removed.Since you are having the operation tomorrow and it’s too late to get a second opinion from a different Surgeon,then be confident that your Surgeon’s recommendation on how to proceed is correct..
Wishing you an uneventful surgery and prompt recovery.
