Dr. Ash Tewari, a urologic surgeon, built a mobile screening unit that has examined over 10,000 men for prostate cancer since 2022. The traveling facility addresses a gap in preventive care that leaves many men, particularly those in underserved communities, without access to early detection.
Prostate cancer screening remains contentious in medical circles. The U.S. Preventive Services Task Force recommends shared decision-making conversations between doctors and men aged 55 to 69, acknowledging both benefits and risks of screening. Overdiagnosis and overtreatment concern some experts, yet early detection saves lives when cancer is localized and treatable.
Tewari's approach focuses on informed choice. His team screens using PSA blood tests and digital rectal exams, then discusses results honestly with patients. The goal centers on identifying aggressive cancers early while avoiding unnecessary anxiety about slow-growing tumors unlikely to cause harm.
The mobile unit strategy tackles real barriers. Transportation, work schedules, and medical mistrust keep many men—especially Black men, who face higher prostate cancer mortality rates—from routine screening. By bringing testing directly to communities, Tewari removes friction from prevention.
The doctor credits the program with catching several cancers at early stages when intervention works best. Without the screening van, those men might have discovered disease only after symptoms emerged, when treatment becomes more complex and outcomes worsen.
This model reflects a practical approach to prevention: meet people where they are, provide transparent information, and let them decide. Tewari's work doesn't sidestep medical controversy about screening value. Instead, it acknowledges that many men lack basic information about their risk and access to testing that helps them make informed decisions.
THE TAKEAWAY: Removing barriers to screening helps men make educated choices about prostate cancer risk, particularly in communities with historic
