I have a few friends with Stage 0. It is cancer, but it just means it hasn't traveled elsewhere, that is it is "in situ" or in place. And how great is it that anyone is diagnosed as Stage 0 to have caught it that early. So whether we are Stage 0, 1, 2, 3, or 4, we have all been confronted with the concept of our mortality.

cctoo @cctoo, AI do not kill cancer cells, they suppress estrogen which will cause cancer cells to grow. My sister made her decision based on medical facts and discussion with oncologist. I would never 2nd guess her decision. Everyone has to make their own decision.

To clarify, Laurie didn't say that AI's kill cancer cells. She noted that, since her sister did not have chemo or radiation which do kill cancer cells, her sister's oncologist prescribed an AI. As to Stage 0, it is indeed cancer -- "Stage 0 breast cancer, ductal carcinoma in situ (DCIS) is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct. In Stage 0 breast cancer, the atypical cells have not spread outside of the ducts or lobules into the surrounding breast tissue."
