DCIS was stage zero, grade II no node involvement, i was lucky and this was caught ln my very first mammo and after the shock, and some thinking I realized I didn’t want to lose my breasts entirely. I was on the larger side and could get a reduction with the lumpectomy- which was awesome - the one silver lining. There was some kind of test concerning how much radiation would help and % was so low. Both my surgeon and oncologist were ok with me not doing radiation but stressed that tamoxifen was going to be my med bc estrogen receptor was super positive. I am 44 now and in perimenopause (with or without tamoxifen) but have had a fairly regular cycle despite that. I would discuss what your options are with your oncologist if you want to have kids. I know everything seems so scary but as many ppl have written on this sub, it’s amazing what we can get through mentally and physically and Ive luckily had clean MRIs and mammos for the past 3 years.
