Breast Cancer – DCIS

Transcript

So what is DCIS? So DCIS is ductal carcinoma in situ, and it is technically a stage zero breast cancer. So DCIS is when the cancer cells develop in the ducts of the breast, but they haven’t gone past that duct into the other breast tissue. So DCIS is still considered a cancer in the fact that it still needs treatment. If DCIS weren’t treated, it would eventually go into an invasive breast cancer.
