Eli5: How do companies test invasive treatments like freezing fat off or liposuction? Wouldn’t many people die/be seriously injured in the process of making it “safe” for the customers?

Question

Are there really people that just sign up to be guinea pigs for these intense procedures in the testing phase?

Answer 1

Devices go through strict testing on animal models before a human can even come near it.

They know the treatment is atleast safe on mammals, which are very similar to us in terms of physiology. This is not always the case, sometimes clinical trials on humans do run badly.
