Who benefits from a preventive health assessment, and who does not

What the evidence shows about health checks

The value of an assessment depends on who it is for. A Cochrane review of 17 randomised trials, 15 of which reported outcome data from 251,891 people, found that general health checks offered to adults unselected for disease or risk had little or no effect on total mortality or cancer mortality [1].

The same review notes that screening leads to more tests and treatments, which can harm as well as help [1]. Those trials offered the same checks to everyone. For one person whose age, history or risk factors point to particular tests, guidance from screening bodies gives a clearer answer.

A single reading is also only a starting point. NICE advises that a clinic blood pressure between 140/90 and 180/120 mmHg is confirmed with ambulatory or home monitoring before high blood pressure is diagnosed [2], and many results found at a check deserve the same second look.

Tests with good evidence for people without symptoms

The US Preventive Services Task Force grades a preventive service A or B when it finds a high or moderate net benefit [3]. Its list for adults is specific, and nearly every item names an age range or a risk group [3].

• Blood pressure screening for adults aged 18 or older [3]
• Colorectal cancer screening for adults aged 45 to 75 [3]
• Screening for prediabetes and type 2 diabetes from 35 to 70 in people with overweight or obesity [3]
• A statin for adults aged 40 to 75 with one or more risk factors and an estimated 10-year cardiovascular risk of 10% or more [3]
• Hepatitis C screening for adults aged 18 to 79 [3]
• Annual low-dose CT for lung cancer from 50 to 80 in people with a 20 pack-year smoking history who smoke or stopped within the past 15 years [3]
• Mammography every two years for women aged 40 to 74 [3]

What UK guidance recommends

In the UK, the National Screening Committee advises on screening for whole populations. Of the 26 adult conditions it lists, it recommends screening for 7, among them bowel, breast, cervical and lung cancer, and it does not recommend population screening for conditions such as ovarian cancer, dementia, atrial fibrillation or diabetes [4].

Its 2026 review of prostate cancer concluded that screening every man is more likely to cause harm than good, and recommended PSA testing every 2 years only for men aged 45 to 61 with a BRCA2 variant and a relevant family history [5].

For the heart and circulation, NICE advises estimating 10-year cardiovascular risk with the QRISK3 tool for people aged 25 to 84 without cardiovascular disease, and reviewing that estimate over time for people over 40 [6]. It also advises telling people their absolute risk and the absolute benefits and harms of any treatment over 10 years [6].

Who benefits most

An assessment is most useful when its results are likely to change what you do. It tends to help people in these situations.

• You are over 40 and have not had your blood pressure and cholesterol checked in some years
• A parent, brother or sister had heart disease, a stroke, diabetes or cancer at a young age
• You smoke, or stopped within the past 15 years
• You were told a reading was borderline and it was never checked again
• You are about to start something demanding, such as a new training programme or a long posting abroad, and want a baseline
• You want one doctor to bring results from different countries into a single plan

Who it does not suit

It is the wrong first step for new or worsening symptoms, which need a doctor promptly rather than a planned assessment. A same day GP appointment is the better start. If you have chest pain, sudden breathlessness, weakness on one side of the body or severe bleeding, call 999 in the UK or the local emergency number elsewhere.

It also helps less if you are hoping that more tests will bring certainty. Every test can raise a false alarm or give false reassurance, and further tests carry their own risks [1]. If a finding that may never matter would worry you, say so, and the doctor will shape the tests around what you want to know.

Questions to ask before you choose an assessment

Ask these before any test is ordered, so that each test is tied to a decision you would make.

• Which of these tests would change what I do?
• What is my estimated 10-year risk of heart disease, and what would lower it?
• Which screening am I due for at my age, and which can wait?
• What happens if a result is borderline or unexpected?
• Who will explain the results to me, and when?

How The Wellness can help

The executive physical is a full day with one physician, covering your history, advanced bloodwork, an ECG and body composition, with every result reviewed with you the same day and a written plan. For a simpler start, the Core Wellness blood test covers a full blood count, liver tests, lipids, HbA1c, thyroid function, inflammation, ferritin and vitamin D, and a doctor explains the results.

Every doctor is GMC registered, and regulated services are delivered through registered partner clinics and accredited laboratories. Our clinics are on Baker Street in Marylebone and Eccleston Street in Belgravia, and appointments are arranged with partners in 12 city pages beyond London.
