Pathology Report~

Since reviewing my pathology report.... I noticed that my type of DCIS is Comedo Nucelear grade 3+ which is a high grade of DCIS:

Comedo type DCIS. Comedo looks and acts differently from other in situ subtypes. Comedo tends to be slightly more aggressive than other forms of DCIS. These cells are closer to invasive breast cancer cells in how they look and behave than other forms of DCIS. Comedo cells look different under the microscope because the center of the duct is plugged with dead cellular debris, known as necrosis. Necrosis seen under a microscope in DCIS usually means that the cells are fast-growing and are generally more aggressive or high-grade. Also, microcalcifications (small abnormal calcium deposits) are frequently seen in the areas of necrosis.

Nuclear grade refers to the rate at which the cells are dividing to form more cells (called proliferation). Cancer cells that divide more often are faster growing and more aggressive than those that divide less often. The nuclear grade is determined by the percentage of cells that are dividing. Cells have different grades ranging from 1 to 3.

Remember, the lower the grade, the more normal the cell. While high-grade DCIS is more likely to become an invasive cancer, it is also the easiest to contain. It tends to grow in a continuous pattern within the duct and is more localized within the breast. Low grade lesions tend to have more gaps and can be more widespread.
All 11 sections removed during the biopsy were cancerous... Hopefully it is still contained.
