Lumpectomy??

I was diagnosed with stage one invasive carcinoma with mixed ductal and lobular features in November. Since that diagnosis, an additional area in the same breast was diagnosed with atypical ductal hyperplasia. When I am talking to doctors, a lumpectomy seems reasonable and I leave feeling confident with my decision, BUT I spend the next nights, days and weeks agonizing over that decision. I can’t find much from people who have had a lumpectomy on this forum. Most seem to go with a mastectomy. Is there anyone willing to share about their lumpectomy experience?
