Prostate Cancer

Prostate cancer is the most common cancer among men, but it can often be treated successfully if found early. In fact, about 1 man in 6 will be diagnosed with prostate cancer during his lifetime. Prostate cancer occurs mainly in older men. About 6 cases in 10 are diagnosed in men aged 65 or older, and it is rare before age 40. The average age at the time of diagnosis is about 66.

Prostate-Specific Antigen

The most common method of detecting prostate cancer currently is by measuring prostate-specific antigen (PSA) levels. Along with other clinical considerations, if a man's PSA level is high, he may be a candidate for biopsy to determine whether or not he has prostate cancer. However, PSA is only prostate-specific and not cancer-specific. This means that other conditions, such as urinary tract infection and riding a bike, can result in elevated PSA levels. As a result, only 25% of men who have a high PSA level between 4.0 and 10 ng/mL will have prostate cancer and thus, will have undergone an unnecessary painful biopsy procedure.


We at Cleveland Diagnostics are developing a blood-based assay to more effectively and accurately investigate prostate cancer biomarkers based on structure, not concentration.
