I read about so many people who try clinical trials and I am so undecided about trying one. I guess what the problem is that when doing a clinical trial, a person has to go for CT scans about every 2 months. My fear is not only the added radiation, but getting injected with the IV contrast, as eventually it could cause problems with a person's kidneys. I know that clinical trials monitor people very carefully and I think that's great, but still I'm afraid. If anyone could share their thoughts on clinical trials I'd appreciate it.
