The phased development of prostate disease with an increasing deepening of pathological changes can last from several months to 10 years or longer.

The U.S. Preventive Services Task Force (USPSTF) is an independent panel of experts in primary care and prevention who systematically reviews the evidence of effectiveness and develops recommendations for clinical preventive services.

Prostate cancer screening is currently controversial:
For men aged 55 to 69 years, the decision to undergo periodic prostate-specific antigen (PSA)–based screening for prostate cancer should be an individual one. Before deciding whether to be screened, men should have an opportunity to discuss the potential benefits and harms of screening with their clinician and to incorporate their values and preferences in the decision. Screening offers a small potential benefit of reducing the chance of death from prostate cancer in some men. However, many men will experience potential harms of screening, including false-positive results that require additional testing and possible prostate biopsy; overdiagnosis and overtreatment; and treatment complications, such as incontinence and erectile dysfunction. In determining whether this service is appropriate in individual cases, patients and clinicians should consider the balance of benefits and harms on the basis of family history, race/ethnicity, comorbid medical conditions, patient values about the benefits and harms of screening and treatment-specific outcomes, and other health needs. Clinicians should not screen men who do not express a preference for screening.
The USPSTF recommends against PSA-based screening for prostate cancer in men 70 years and older.
It depends on your risk factors and age.

* Age 50 for men who are at average risk of prostate cancer and are expected to live at least 10 more years.
* Age 45 for men at high risk of developing prostate cancer. This includes African Americans and men who have a first-degree relative (father or brother) diagnosed with prostate cancer at an early age (younger than age 65).
* Age 40 for men at even higher risk (those with more than one first-degree relative who had prostate cancer at an early age).
There are some concerns with testing, though - https://www.cancer.org/cancer/prostate-cancer/detection-diagnosis-staging/detection.html
