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.

PSA test results can be interpreted a number of different ways and there may be differences in cutoff values between different laboratories. 1  The value for total PSA below which the presence of prostate cancer is considered to be unlikely is 4.0 ng/ml (nanograms per milliliter of blood).f the DRE is normal but the PSA is moderately elevated, a free PSA test may be used to look at the ratio of free to total PSA. This can help to distinguish between prostate cancer and other non-cancer causes of elevated PSA. Other tests may also be recommended if either the PSA or the DRE is found to be abnormal.
