Lung screening if you have smoked

If you have smoked, the honest question is which test matches the lungs you have now, not a lecture about the years behind you. A chest X-ray, spirometry and a low-dose CT scan are different instruments. MRI is a weak look at lung parenchyma. An Advanced Health MOT that includes a chest film is not a lung-cancer package. A laboratory flag is not a diagnosis, and a clear picture is not an all-clear.

If you are coughing blood, have new unexplained breathlessness, chest pain, a voice that has changed and stayed changed, or a cough that is getting worse, this is the wrong appointment. NICE suspected-cancer guidance (NG12) sends people aged 40 and over with unexplained haemoptysis on a suspected-cancer pathway, and it uses urgent chest X-ray for combinations of cough, fatigue, breathlessness, chest pain, weight loss and appetite loss, especially in anyone who has ever smoked. See a GP, use that pathway if you are offered it, and use 999 or A&E for emergencies. A private screening date does not replace that.

The Health Screening Clinic has done doctor-led respiratory assessment at 117a Harley Street since 1984 and is CQC registered. Lung screening here is a consultation, an examination, spirometry, imaging that changes by tier, and an in-person review. It is not a promise that you will be enrolled in the NHS targeted programme, and it is not a smoking-cessation clinic by another name.

What the NHS and the UK NSC already recommend

The UK National Screening Committee recommended targeted lung cancer screening in 2022 for people aged 55 to 74 identified as being at high risk, using low-dose computed tomography. The committee said the evidence showed a reduction in lung-cancer mortality when the programme is resourced and quality assured, and that smoking-cessation support should sit beside it. That is targeted screening, not an invitation posted to every adult who has ever had a cigarette.

In England the large-scale starting point was the Targeted Lung Health Check programme, later brought under the NHS England Lung Cancer Screening Programme. Eligibility is not a private clinic's to award. Do not treat a Harley Street booking as a way of joining that programme, and do not treat absence from it as a reason to skip a GP if you have symptoms.

NICE NG122 covers diagnosis and management of lung cancer rather than the screening offer. NICE NG12 remains the symptom pathway. A private LDCT is extra imaging, read by a doctor. Chest X-ray is still the first-line film NICE uses for many symptomatic combinations, and it is less sensitive than low-dose CT for small nodules. MRI, including the torso series on a full-body MOT, is a weak look at air-filled lung. If the organ is lung parenchyma, do not buy MRI and hope.

Essential, Advanced and Elite lung packages

The Essential lung screen currently costs £395. It includes a consultation and physical examination, spirometry, a chest X-ray, and an in-person review of the results. That is a doctor-led look at function and a plain film. It can show larger structural change, collapse, obvious masses and some bony findings. It will miss nodules that LDCT is designed to look for. Spirometry measures airflow and volume. It can flag obstructive or restrictive patterns. It does not see a nodule.

The Advanced lung screen currently costs £999. It keeps the consultation, examination and spirometry, replaces the chest X-ray with low-dose CT of the chest, and still includes an in-person review. That is the imaging change that matters if the question is small nodules rather than a baseline film. Low-dose CT still uses ionising radiation, at a lower dose than a standard diagnostic CT. It still finds incidental nodules, most of which are not cancer. A nodule is a finding, not a diagnosis. British Thoracic Society guidance exists for how nodules are measured and watched. The doctor who reviewed you should say whether a nodule needs a repeat scan, a different test, or no action.

The Elite lung screen currently costs £1,599. It includes everything in the Advanced lung package and adds an EarlyCDT lung blood test. That blood test looks for autoantibodies that can be associated with lung cancer. It is not a diagnosis. It is not an all-clear. It can be negative when disease is present and reactive when it is not. Imaging still matters. A blood result without the LDCT, the spirometry and the examination is a clue without a map.

Most results for these packages are ready in three to five working days. Specialist assays such as EarlyCDT can take longer. You come back for a face-to-face review. A flag on the film or the bloods is a reason for a plan, not a sentence.

Why an Advanced MOT chest X-ray is a different booking

The chest film on that MOT is the same kind of picture as Essential lung screening. It is not low-dose CT. It is not a lung-cancer package.

The Advanced Health MOT is £999. It is a wide preventative visit: examination, metabolic bloods, hormones, spirometry, VO2 max, a chest X-ray, and DEXA when clinically indicated, plus four GP appointments over a year.

If you booked Advanced as a Health MOT because you wanted LDCT after years of smoking, you booked the wrong list. The MOT can still be the right visit if the question was cholesterol, thyroid, bone density when indicated, and a doctor-led baseline that happens to include a chest X-ray. Say which question you brought. Organ screening and a MOT can sit beside each other. They should not be used as quieter names for one another.

Ultimate MOT MRI covers torso among other regions. MRI remains a weak look at lung parenchyma. Elite MOT adds ultrasound and tumour markers of other organs. CEA is not a lung screen. If the organ is lung, use the lung list on the cancer screening page.

What a result can and cannot say

A normal chest X-ray means the film, that day, did not show a change the reporter judged important enough to flag. It does not mean the lungs are free of disease. A normal LDCT means no nodule or other finding was reported at the threshold used. Small lesions can still sit below that threshold. Interval cancers happen in every screening programme. UK NSC language is that screening tests tend to be simple rather than very accurate, and that they often need further tests.

A nodule, a scar, or an enlarged node is not a diagnosis. Follow-up imaging is sometimes the honest further investigation. False positives lead to extra scans. False negatives lead to false reassurance. Paying privately does not remove either.

Spirometry outside its predicted range is also not a diagnosis on its own. Technique, effort, asthma, COPD and infection all move the numbers. If you still smoke or vape, say so. The clinic can talk about stopping. A scan is not a substitute for that conversation.

Tips and tricks

• Name the picture you want.
• A chest X-ray with spirometry is Essential.
• Low-dose CT with spirometry is Advanced lung screening.
• The autoantibody blood test sits on Elite, on top of that CT, and still needs the pictures.
• Do not use MOT MRI as a lung shortcut.
• Bring a smoking history in years and, if you know it, pack-years, plus previous chest films, CT reports and inhaler names.
• Say if you have coughed blood, lost weight, or become breathless on a flight of stairs, because those facts change the appointment from screening to a GP or urgent pathway.
• Keep any NHS targeted lung invitation if one arrives.
• A private LDCT does not enrol you in that programme and does not replace it.
• Ask how nodules will be measured and who will explain the report.
• Leave three to five working days for results, and keep the review.
• Wear clothes you can breathe in for spirometry.
• Continue regular inhalers unless you were told otherwise.
• Do not invent a stop list.

Things to avoid

• Do not wait for a screening date if you are coughing blood, losing weight, or becoming more breathless. That needs a GP or urgent pathway, or 999.
• Do not treat an Advanced MOT chest X-ray as a low-dose CT lung package.
• Do not treat MRI as a lung-parenchyma test.
• Do not treat EarlyCDT, or any other blood test, as a cancer screen or an all-clear.
• Do not assume a private booking will place you on the NHS targeted programme.
• Do not skip a GP because a film last year was reported as normal.
• Do not hide current smoking from the doctor who has to read the scan. Or book at The Health Screening Clinic on 020 7183 7056.

If you want a doctor-led look at the lungs rather than a general MOT film, review the current lung screening packages on the lung cancer screening page.

For scan results nobody expected, read incidental findings on a private scan. For choosing between organ packages, see whole-body cancer screening versus an organ package.

Frequently asked questions

I have smoked. Which lung test should I book?

Essential at £395 is examination, spirometry and a chest X-ray. Advanced at £999 replaces the X-ray with low-dose CT. Elite at £1,599 adds an EarlyCDT lung blood test on top of that CT. MRI is a weak look at lung tissue. An Advanced MOT chest film is not an LDCT package.

Will this enrol me in the NHS targeted lung programme?

No. The UK NSC recommended targeted LDCT screening for people aged 55 to 74 at high risk. NHS England runs that as a national programme with its own eligibility rules. A private booking is a separate assessment.

Is a chest X-ray enough after years of smoking?

It can show larger change and is the film NICE uses first for many symptom combinations. It is less sensitive than low-dose CT for small nodules. Choose the picture that matches the question, rather than assuming the cheaper film is the same job.

Does a normal LDCT mean I do not have lung cancer?

No. It means the scan that day did not show a finding the reporter flagged. Screening can miss disease. Get new symptoms checked even after a reassuring report.

What is the EarlyCDT blood test for?

It is an autoantibody blood test on the Elite lung package. It is not a diagnosis and it is not an all-clear. Imaging and examination still have to be read.

I am coughing blood. Should I book screening?

No. NICE NG12 uses a suspected-cancer pathway for unexplained haemoptysis at 40 and over. See a GP now. Use 999 or A&E if you are unwell.

Do I need a GP referral?

No. The clinic at 117a Harley Street accepts self-referral, has been there since 1984, and is CQC registered. Symptoms still belong with a GP first.
