Mine was not as serious as a tumor, but it indicated the attitude at Straight. About halfway through my time, I came down with Strep Throat. My host parents knew I was sick, as did my oldcomers, but I never said anything to staff myself because I knew what would happen. I lost ten pounds over the next two weeks (I was skinny in the first place).
The thing is, Strep had to be going around the program at the time, because I didn't have it when I went in. And yet they weren't watching for more people to come down with it. Plus, they apparently ignored the request from my host parent that I see a doctor.
I found out what it was when my father pulled me from the program. He took me to a doctor, who immediately suspected Strep.
It may have been a lucky break for me to get sick, though, because I looked like hell, and that may have sped things up when my parents started to question the program.
