I have served 15 years on active duty and now 10 years Air Force Reserves. I was involuntarily mobilized Dec 2016 and deployed in Jan 2018. While deployed I noted a small lump in my breast. I didn't think it was anything serious until 3 months later it had tripled in size. I went to the clinic. It was evaluated with an ultrasound and determined that I needed medevac. June 2017 I was diagnosed with Stage 3a er/pr + HER- breast cancer. I was placed on Medcon for the duration of chemo and radiation but Medcon was terminated the last day of radiation. I am still waiting for the LOD determination to be completed but keep being told "it can't be ILOD because cancer is preexisting". However, doesn't the "eight year rule " apply to my circumstances?
