- Causes of
- Getting a
- When DCIS
a Second Opinion
- How the tissue specimen was received by the pathologist.
For example, the number of tissue samples or blocks; the fixative used;
and the orientation; the location in the breast; and what type of surgical
procedure was used to get this tissue sample.
- The size of the sample tissue or specimen in three dimensions:
height, width and depth.
- Whether the entire specimen was examined.
- The features of the DCIS such as nuclear grade, necrosis,
- An estimate of the size or extent of DCIS, if possible.
- The location of microcalcifications: Are these present
within the DCIS tissue, the normal breast tissue, or both?
- Whether or not DCIS is found in the margins of the tissue
samples. If the pathologist is able to determine how far the DCIS is
from the margin, it should be stated in the report.
From these descriptions your doctor should be able to learn:
- The size of the DCIS.
- An assessment of the tissue around the DCIS (the margins), particularly:
- Whether a ring of uninvolved tissue is present around all the DCIS.
- The size of the clean tissue around the DCIS.
- The type or types of DCIS that are present.
