I had two types of breast cancer according to my surgical pathology report. IDC and DCIS with microinvasion. I believe this is pretty common as I think the IDC comes from the DCIS. The tumor itself was very small, only 20 mm, which is slightly less than an inch. I had a lumpectomy and radiation, but refused chemo because no lymph nodes involved. My surgeon says I've had a charmed recovery, so I feel very blessed.
