I had ILC. 12mm. Lumpectomy. Last Sept. Had hysterectomy a year before that because I had endometrial cancer. I am also thin but otherwise healthy except two years ago diagnosed with RA. I control it with methetrexate and plquenil. Because of the testing I have had there is a 92% chance I will not get my BC back so I did not have radiation and opted not to do the hormone blocker. Because I have osteopinia and the blocker would throw me into osteoporosis. I lift light weights and walk and use elyptical 5 days a week. My mammos every year with ultrasound did not show my breast cancer. I found the lump myself. It showed up with mri with dye. I am having only mris now and ultra sounds but am having a hydration iv to clear the gadioleum dye from my system. My hair thinned but taking neutrofol everyday. We will see. I just. Keep moving and checking my self. Good luck to you.
