lung cancer twenties

What are some diseases that people in their twenties can get? ?
I need a list of common inherited diseases that someone in their 20s can get and possibly die from it. Does lung cancer count as one of them? I’m not sure if it’s a genetic disease or not. But anyway, please give me a list of all possible diseases. I’ll do my research from there- after I get a new name suggestions. Thank you.
H.I.V,, brain tumour,, breast cancer!!!! it dosn’t matter what age you are you can die of a heartattack on ur 20’s, so anythin realli.
