Do I understand this process correctly ? Simply put, margins are analyzed for the presence of DCIS cells. The closer that DCIS cells are found to the specimen perimeter ( margins ) the greater the statistical probability that more DCIS is present in the surrounding tissue ? In reality, there may or may not be more DCIS in the surrounding tissue ? But, you simply don't know until the tissue is removed and analyzed ?

Thank you for the clarification.

    What you said is correct!

    I would add, however, that the additional cancer that may or may not be in the surrounding tissue can include an invasive component in addition to more DCIS. 

    Also, there are issues of whether any additional cancer is DCIS tumor (very large numbers of cells) or residual DCIS (very small numbers of cells), but that is something you have to rely on the oncologists to assess and explain.
