A lot would depend on the biology of your tumor, your family history, how wide spread, or if you have a genetic mutation. For DCIS, stage 0 breast cancer, without the above factors, if the DCIS is hormone positive, it is usual to take anti hormones when you receive lumpectomy, with or without radiation. With mastectomy, it may or may not be given, depending on your individual factors, such as mentioned above or young age. My mother had DCIS and had a lumpectomy followed by radiation twice a day for 5 days. For IDC, I had a partial mastectomy, 6 weeks of rads, and take Femara. I also have an implant. It comes down to a personal choice, and what you are most comfortable with, and what your doctor recommends.
