The PCA3 test can show likely it is that prostate cancer is present—and if it is unlikely, unnecessary biopsies can be avoided. The PCA3 test is a new test available in the UK for the first time to specialists looking after men who may have prostate cancer. The prostate Cancer Charity considers the test to be a useful development in prostate cancer diagnosis because of its potential to cut down on unnecessary pain and side effects from invasive biopsies.

Prostate Specific Antigen (PSA)

PSA is a protein produced by both normal and cancerous prostate cells.
The PSA test measures the level of PSA in the blood. Because PSA is produced by the body and can be used to detect disease, it is sometimes called a biological marker or tumour marker.
This test should be done along with PCA-3 to enable the doctor to make decision on diagnosis if PSA result is raised.
