Benefits and risks of full-body scans: Doctors share their insights

Key Points:

• Full-body MRI scans, popularized by celebrities and figures like former "Bachelor" contestant Josh Seiter, aim to detect early signs of diseases such as cancer and heart abnormalities before symptoms appear, using technologies like MRI, CT, or PET scans.
• Providers like Prenuvo promote these scans as a "virtual physical" offering comprehensive health data analysis, but the high cost (up to $2,500) and lack of insurance coverage for routine screening limit accessibility.
• Medical experts express concerns about the scans, citing risks of false positives, overdiagnosis, overtreatment, and increased anxiety, with major health organizations and the FDA advising against routine use in healthy, asymptomatic individuals due to insufficient evidence of benefit.
• While some early-stage cancers have been detected in studies of full-body scans, experts recommend more targeted diagnostic approaches based on patients' symptoms, history, and genetic risk rather than broad screening.
• The medical community is shifting towards personalized healthcare enhanced by genetics and artificial intelligence, favoring directed testing over full-body scans until more definitive data on long-term outcomes and benefits become available.
