I was diagnosed with DCIS / Stage 0 in 2007 Even though it was stage 0, the DCIS comprised a large area, I followed the advice of my radiologist and the pathologist, both of whom recommended a lumpectomy followed by radiation. I didn't take any follow-up preventive medication of any kind. I would have found it much more stressful to be continually aware of the DCIS remaining in my breast than to suffer the temporary discomfort of surgery.

There are never any guarantees, of course, but now, 19 years later, I am comfortable that I made the right decision. I wish you all the best!
