Wow! I'm a lot like you, Isidella - I want to do clinical trials, and test out new drugs. My dad has cancer, so it's interesting learning about how drugs get approved.
For example, IL-2 only works for <10% of cancer patients, yet for many cancers it's the only treatment available. Sucks huh?
Sometimes it seems like once a drug has been FDA-approved, they try to make sure it still has a market, even when it's old and proven to be virtually ineffective.
