Chana bat Gittel is a friend of mine who is in her early 30s- she was diagnosed (early) with C in the breast- they did 2 surgeries- they didn't get it all out the first time so they did a second one (I think lumpectomy) and we believe the second surgery WAS successful- BH- but to be on the safe side she will also have to do some chemo and radiation.
Thank you and may Hashem send you Blessing and Happiness. Gmar tov...
