Actor Anupam Kher and Congress leader Shashi Tharoor recently underwent full-body health scans, sparking curiosity about whether such comprehensive check-ups are advisable for people in their seventies.

Full-body scans promise a detailed picture of what is happening inside the body, from the heart and lungs to bones and soft tissue. But doctors say the decision to get one should be guided by medical advice, not curiosity alone.

What a Full-Body Scan Covers

A full-body scan typically combines imaging tests that examine major organs and systems in a single session. It can flag issues such as blocked arteries, tumours or bone density loss, sometimes before symptoms appear.

For older adults, early detection can make treatment simpler and more effective, which is why preventive screening gains importance with age.

How Often Should You Get One

There is no single rule for how often a healthy person in their seventies should undergo a full-body scan. Most doctors recommend regular check-ups tailored to individual risk factors such as family history, lifestyle and existing conditions.

Annual or biennial comprehensive health assessments are common advice for senior citizens, while full-body imaging is usually recommended only when a doctor sees a specific reason for it.

The Caveats to Keep in Mind

Scans can also throw up false alarms or find harmless abnormalities that lead to unnecessary worry and further tests. Radiation exposure from repeated imaging is another factor doctors weigh carefully.

The sensible approach, physicians say, is to discuss screening with a trusted doctor rather than booking scans on your own. Prevention works best when it is personalised, not one-size-fits-all.

Many hospitals now market executive health packages aimed at senior citizens, combining blood tests, cardiac screening and imaging into a single-day visit. Doctors caution that more testing is not automatically better testing, and that a package designed for everyone may not be right for anyone in particular. A personalised plan drawn up with a physician remains the gold standard.
