I've met a few people who had "my" cancer, and it does create an instant bond - a bond that I think is there for any fellow cancer survivor on some level, but probably even more with the same diagnosis. It's really cool when I can meet little kids and they can see my scar, see that my hair did grow back, and also see that I went on to grow up and have a good life. You feel their excitement when treatments go well, and it's heartbreaking when they don't.
I forgot to say, for the details of your treatment, you should be able to get all the medical records with details of your diagnosis and treatment from your hospital. I have all of mine, and they're pretty interesting (and sometimes useful) to have. I was able to request mine from another state, so you wouldn't necessarily even have to pick them up in person.
