Jay K. Harness, MD, FACS: Stage 1 breast cancer is an invasive breast cancer that means the cancer has grown through the walls of the duct into their surrounding tissue.  Stage 1 breast cancer typically means that the lymph nodes are not involved and typically it also means that the cancer is 2 cm or smaller in size.

Now being stage 1 is good that your long-term survival for stage 1 breast cancer by and large are very-very good and the treatment of stage 1 breast cancer is treatments of what we are taking about in subsequent videos.  We have to control the cancer within the breast and we will talk about the surgical options for that.  We will also talk about the other adjunctive things that we do.  It may involve radiation therapy, may involve anti-hormonal therapy.

Typically, but not always, stage 1 breast cancer usually does not involve chemotherapy, but there are certainly exceptions to that and I will talk more about that under adjuvant chemotherapy.
