I have no idea, it could have been a decade or it could have been a year. My tumor was 6cm and had spread to my bones and liver. I had worked on a piece of old army equipment that shouldn’t have been in our lot and when I asked the my NCO about it later, it was an odd rush job for a vehicle that looks like it had been deadlined for decades, he said brigade was looking at serial numbers and this one had been involved in a “nuclear incident”. The army will never confirm this and the NCO wrote down that he did the inspection like he was supposed to. I was diagnosed 4-12 months later, I don’t really remember when it was anymore. I was crawling all over that thing for two days.
