Dr. Ash Tewari has transformed prostate cancer screening into a mobile operation. His traveling testing facility has screened over 10,000 men since its 2022 launch, detecting cancers that might otherwise have gone unnoticed.
Tewari, a urologic oncologist, built the screening program on a simple principle. Prostate cancer kills American men at rates that deserve urgent attention, yet access to early detection remains uneven across communities. His mobile clinic removes barriers by bringing screening directly to neighborhoods rather than waiting for men to navigate healthcare systems.
The facility combines PSA blood tests with digital rectal exams, the two primary screening tools for prostate cancer. Tewari's team provides results and connects men who need follow-up care to appropriate specialists. Some men screened have received early-stage diagnoses that dramatically improved their treatment outcomes and survival chances.
Prostate cancer screening remains controversial in medical circles. The U.S. Preventive Services Task Force recommends shared decision-making between doctors and men about screening benefits and risks, particularly for men aged 40 to 69. Overdiagnosis poses real concerns, as some detected cancers grow slowly and never threaten life. However, aggressive cancers caught early respond well to treatment.
Tewari's approach acknowledges this complexity. His team educates men about screening benefits and limitations before testing. They prioritize men at higher risk, including Black men who face disproportionately high incidence and mortality rates, and men with family histories of prostate cancer.
The mobile clinic model addresses a healthcare access gap. Many underserved communities lack convenient access to preventive screening. By eliminating transportation barriers and offering free testing, Tewari reaches men who might skip appointments at traditional clinics.
Results speak directly to impact. Among the 10,000 men screened, his team
