Hing high PSA levels isn’t the only sign of prostate cancer. Your PSA levels can still be low — even below 0.5 ng/mL — if you he prostate cancer.
That’s why a doctor will usually recommend other tests besides a PSA test to diagnose prostate cancer, especially if you’re experiencing other symptoms or are at high risk.
A 2020 study of more than 33,000 men between 55–74 years old found that Black men were at an especially high risk of aggressive prostate cancer even with PSA levels under 1 ng/mL.
