Usain Boltâs âTo Di Worldâ, also known as bolting, is a photo fad that involves leaning back and pointing both index fingers towards the sky with the right arm cocked and the left stretched out in tribute to the victory pose of the Jamaican professional sprinter and Olympic gold medalist Usain Bolt.
Diagnosing prostate cancer. At the moment, men with symptoms of prostate cancer have a number of tests to find out if they have cancer. The tests include a PSA (prostate specific antigen) blood test and a rectal examination. A PSA test is not a very accurate test for prostate cancer.Some men with a high level of PSA in the blood have prostate cancer. But some men who have prostate cancer have a low PSA level. And PSA levels can also be raised by several other medical conditions not related to cancer.So, if you have a raised PSA, you need more tests to find out if you have prostate cancer.iagnosing prostate cancer.

Free PSA Test Helps in Prostate Cancer Diagnosis by William J. Catalona, M.D. A relatively new and helpful addition in the diagnosis of prostate cancer is the free PSA Test. This blood test is done in addition to the PSA Test and the finger (digital) examination. The PSA Test measures a protein in the blood that is produced only by the prostate gland. Some of the PSA in blood is bound to other proteins and the rest circulates freely. This free PSA is a damaged variant of PSA that no longer is able to bind to other proteins and thus circulates in the blood in the unbound (free) form.
