The PSA doubling time estimates how quickly PSA is rising between two tests using an exponential growth model.
Enter up to 6 PSA test values (within a 12 month period; minimum 2 values) and their dates to see the estimated doubling time in days and months.
For clinical interpretation, formal methods typically use several PSA points, since reliability improves when at least three recent measurements are available.
And if you want to work with someone to change your lifestyle, nutrition, and physical activity to dramatically slow down prostate cancer growth that will reflect on your PSA and PSA doubling time and grow stronger and healthier, you can start working with me now.
