Your physician will want to rule out an infection and/or an enlarged prostate, both of which can cause the PSA levels to increase. A repeat PSA should be obtained. There are other tests such as free PSA, PCA3, PHI and others which may be useful in some instances. Free calculators can help integrate your PSA with your age, family history, and other parameters to estimate your risk of prostate cancer and high-grade prostate cancer.
