I have two “beliefs”, one probably true, the other…well…
The first is that your DNA has a LOT more to do with cancer and cancer treatments than anyone suspects. From anecdotal stories about “my grandfather smoked 10 packs a day and never got cancer”, to people who just never respond to cancer treatments that work for most people, I think it isn’t just random.
They are beginning to understand this, with those interminable commercials for drugs that work “in people with non-HIR2” or whatever. The trouble is, there’s no way to study this without letting a lot of people die, or worse even, poisoning them.
Some people have genetics that will always give them cancer, some have genetics that will give them cancer with the right triggers, toxins, whatever, and some who will likely never get cancer if they breathed cig smoke 24 hours a day.
To study it, you’d have to map everyone’s DNA, then spend years tracking which approved treatments do what to who, and only then can you begin to experiment. IF ethically it could even be done.
The second one I “believe”, and not to the point I’m going to say it anywhere but here, is I believe in “consciousness quantum reality”, that choices, basically, determine reality. WE decide if that damn cat is dead or alive. And some people are “better” at it than others, which could explain luck.
