I think it's different for everyone, but I had my right breast removed in February, 2017, along with 10 lymph nodes. Four chemo sessions and 30 radiation treatments, and after two years I'm clean. Started on Femara but too much bone pain so switched to Irimidex and no appreciable side effects. I take Boniva once a month to keep my bones strong. Mammograms every year but so far no need for MRIs or other scans. That's about it. I'm 81 and I actually feel pretty good, considering. I had excellent care at two different Cancer clinics and get checkups at each once a year.
