How is prostate cancer diagnosed?

Once the clinical examination has been completed, an ultrasound scan may be performed as a complement. The determination of PSA (a substance specific to the prostate that circulates in the blood) by blood test makes it possible to detect and monitor the disease evolution.

The importance of PSA rate

Depending on the stage of the disease and the treatment used, your doctor’s interpretation of the PSA level will not be based on the same criteria[1]. PSA tests are often recommended from the age of 50 onwards. The PSA level is increased in cases of prostate pathology but does not lead to the diagnosis of cancer.[2] For this, additional examinations must be carried out.[1]
