Estimate Your Cancer Risk Factor for 20Year Age 64 at 3 PSA (from S3)
Complete the remaining 2 actions to estimate your cancer risk for your report:
 Estimate your cancer risk factor from tables or by using a risk calculator.
 Choose your cancer risk factor for the report: 1X, 2X, 3X or 4X.
NOTE: Repeat the process each time you select a different report combination. Your risk factor will change for each report because the base risk is different for each combination.

After choosing your cancer risk factor, return to step S3. Cancer Risk
Follow the Process to Choose Your Cancer Risk Factor for Your Report
First, estimate your cancer risk for your report by one of three methods:
 Use the sections below for the risk calculators and 4Kscore:
 PCPT Risk Calculator
 ERSPC Risk Calculator
 4Kscore
 Run each risk calculator or note your 4Kscore and use the linked form to estimate your cancer risk factor:
 PCPT Risk Calculator > Learn more, cancer risk factor form and example cancer risk factor form
 ERSPC Risk Calculator > Learn more, cancer risk factor form and example cancer risk factor form
 4Kscore > Learn more and cancer risk factor form
Second, choose your cancer risk factor for the report: 1X, 2X, 3X or 4X:

4Kscore Cancer Risk Factor Estimates
4Kscore acts like a risk calculator that considers a panel of four PSA related blood tests, age, DRE and previous biopsy.
Cancer risk factors based on 4Kscore values are shown below for the 20year age 64 at 3 PSA case:

NOTE: If your 4Kscore is elevated, consider a followup 4Kscore for the same reasons to followup an elevated PSA.
PSA and 4Kscore can be increased by a temporary condition (infection or inflammation) that may moderate at followup.
