The concept of "fitness" is central to evolutionary biology but it's not entirely worked out. There are multiple definitions, doubts about predictive power, problems with internal consistency. Here's a paper from last year attempting to solve some of these problems. doi.org/10.1093/evol...

Sharks absolutely get cancer, and people claiming otherwise are pseudoscientific grifters preying on the desperate.
Even if sharks did not get cancer, eating shark would not cure your cancer any more than eating LeBron James would make you better at basketball.
