Work out prostate cancer risk instantly with clear inputs, formula shown and shareable results.
Calculates PSA density from PSA and prostate volume and interprets the free PSA percentage, the two published refinements used when total PSA is equivocal.
PSA density and free PSA
PSA density = total PSA / prostate volume; 0.15 ng/mL/cc or above raises suspicion. Free PSA below 10% is associated with a higher cancer probability

Benign enlargement raises PSA, so density separates gland size effects from cancer risk.
No. Multiparametric MRI and targeted biopsy remain the diagnostic pathway.
