7. The PSA Level Always Determines if There is Prostate Cancer:

There are numerous myths associated with PSA levels. These include that a PSA of 4ng/ml or less always means that there is no prostate cancer or that a high PSA always means the presence of prostate cancer. However, there is more to a prostate cancer diagnosis than just the PSA levels. Between 15 and 20% of all men with a normal PSA level suffer from prostate cancer, while about only 30% of all men with high PSA levels have the disease.

8. A Normal DRE Means that There is No Prostate Cancer:

The digital rectal exam (DRE) is about 50% accurate in detecting prostate cancer. It lets the physician analyze the presence of induration, a prostatic nodule, abnormal texture or prostate size and tenderness. But the DRE does not confirm whether a patient suffers from prostate cancer, and further examination is often needed.

9. An MRI Substitutes a Prostate Biopsy:

An imaging study including an MRI, CAT scan, or ultrasound is not used to diagnose prostate cancer. They may be requested by the physician to evaluate the presence of suspicious areas to be targeted during a biopsy or to evaluate the extent of the cancer. However, it is a myth that an MRI can substitute a prostate biopsy.
