A 41-year-old member asked:

Is it a problem if my doctor uses psa (protein specific antigen) tests instead of a digital rectal exam for the prostate?

No: Prostate specific antigen (not protein) is a very sensitive marker of prostate function. It very frequently will be elevated before any abnormality is detected by digital rectal exam. However, nothing beats a good clinician being able to feel something on exam. So, really, the two work together to achieve the best results.
