Med students - screen for PSA or no?

Curious what the student opinion is on using PSAs. Yes I'm aware there are new and better tests out but they aren't standard of care in any way yet + are expensive. Nonetheless I've noticed residents are against using it whereas attendings largely like it. Pros: More available data, higher likelihood of catching cancer in a 50 year old patient Cons: More likely to lead to unnecessary biopsy --> complications
