P3-B IFT

I was in Navy from 1974 - 1984. I flew on P3-B Orion Aircraft for about 8 years as an in flight avionics tech. I spent many hours working on APS80 radar systems during that time and logged over 2500 hours of flight time, and God only knows how many hours working on those aircraft on the ground. In 2011 I was diagnosed with Thyroid Cancer and had my thyroid removed. I must now take Synthroid every day. I'm curious if your investigation went anywhere with this issue.
