4. A big prostate, high PSA levels or a vasectomy increase the probability of prostate cancer:
There is no scientific evidence that supports the idea that having a bigger prostate or having higher PSA levels is always correlated to the development of prostate cancer. Similarly, men who undergo a vasectomy do not have a higher risk of prostate cancer.
5. Prostate screening is worthless:
“Although the current method of prostate screening with the total PSA only may not be cost effective, evaluation of individual men with the PSA as well as the free PSA may be. Especially men in certain risk groups such as those with a family history of prostate cancer or those men with an African heritage,” explains the Florida Urological Associates. “Furthermore, prostate cancer is found in all age groups from the 30s on but becomes progressively more common as well as more aggressive with age.”
6. PSA is the only way to diagnose prostate cancer:
The PSA level is an effective method for physicians to evaluate if there is something wrong with the prostate. The prostate-specific antigen is a protein produced by the cells of the prostate and the PSA test evaluates the level of PSA in the blood. This is measured in nanograms of PSA per milliliter (ng/mL) of blood, and it can indicate numerous diseases of the prostate, not just prostate cancer. However, further examination is usually needed to confirm the diagnosis, including a digital rectal exam (DRE) and a prostate biopsy.
