Tumour markers in a MOT

A tumour marker in a Health MOT is a blood protein that some cancers can raise, and that ordinary tissue can raise as well. It is a clue rather than a cancer screen, a diagnosis or an all-clear. The parent question, whether a blood test can detect cancer at all, is answered in a separate article on whether a blood test can detect cancer. This piece is narrower. It is about the markers that appear on Elite and Ultimate, why they sit next to imaging, and why a flagged CEA, PSA or CA-125 still needs a doctor rather than a PDF.

People add markers because a number feels like proof. Laboratories do not work like that. Reference ranges are statistical intervals. Inflammation, smoking, liver disease, menstruation, an enlarged prostate, a benign ovarian cyst and a recent illness can all move a marker. Early disease can leave the same marker inside range. That double failure is why the UK National Screening Committee has not recommended a national programme that uses a general cancer blood test, and why NICE suspected-cancer guidance (NG12) puts PSA and CA125 inside defined symptom-led pathways rather than on a screening menu for everyone.

The Health Screening Clinic has read those numbers at 117a Harley Street since 1984 and is CQC registered. Every MOT still includes a GP consultation, an examination and a review. Markers arrive from Elite, and the pictures that arrive with them are there for a reason.

What Elite includes

Elite is the MOT that adds tumour markers, because it already includes the examination and the sex-specific imaging those markers would need if they flag.

Currently £1,850 for men and £2,095 for women, it takes 2.5 to 3 hours, with a minimum four-hour fast. Women's Elite runs on Thursday and Friday specialist days; men's Elite is available Monday to Friday. Women have CEA and CA-125, alongside consultant gynaecology, trans-vaginal and pelvic ultrasound, a smear, and a mammogram from age 40. Men have CEA and, from age 40, PSA, alongside abdominal, pelvic and testicular ultrasound.

CEA is carcinoembryonic antigen. It is used mainly in people already known to have bowel cancer, to watch for recurrence. Smoking, inflammatory bowel disease, liver disease and other adenocarcinomas can lift it. Early bowel cancer often leaves it ordinary. The NHS bowel programme uses a stool FIT kit, not a CEA blood test. A raised CEA on Elite is a reason for the doctor who examined you to look at the rest of the panel, the abdomen and the history. It is not a bowel diagnosis.

PSA is prostate-specific antigen. NHS pages are plain that a high result does not mean you have cancer, and that an enlarged prostate, infection, recent ejaculation, cycling and breathless exercise can lift it. A low or ordinary-looking result is not a lifetime all-clear. Routine population PSA testing is not currently offered on the NHS. The UK NSC still does not recommend population prostate screening. NICE NG12 uses PSA inside a symptom-led route, with age-banded thresholds, for people who already have urinary symptoms, erectile dysfunction or visible haematuria. On Elite it is extra information from 40, read with the examination and the ultrasound, not a substitute for those.

CA-125 is the marker NICE uses in primary care for persistent symptoms that suggest ovarian cancer, then ultrasound depending on the result. The UK NSC does not recommend population screening for ovarian cancer. The UKCTOCS trial found that screening with CA125 or ultrasound did not reduce deaths from the disease. On Elite the marker sits next to pelvic ultrasound and a gynaecologist, and that combination is the point rather than the number on its own.

If you wanted a single named protein without an examination, that is a different kind of booking. Individual test-name lists of that sort sit with the laboratory service at blood.london, including cancer marker tests, not on this MOT menu. A MOT is not a catalogue of SKUs.

What Ultimate adds for women, and what it still cannot do

Ultimate starts at £2,950 without gynaecology and £3,350 with it. Allow 3 to 4 hours, including 60 minutes of MRI of brain, intracranial and carotid MRA, whole spine and torso. For women it adds HE4 and a ROMA score on top of CA-125. ROMA is a calculation that combines HE4, CA-125 and menopausal status. It is used in some secondary-care settings to help sort pelvic masses, and it is neither a screening test nor a verdict.

NICE HealthTech guidance (formerly DG31, now HTG453) found there was not enough evidence to recommend routine adoption of ROMA in NHS secondary care to decide whether to refer people with suspected ovarian cancer to a specialist multidisciplinary team. That is a limitation, not a footnote. A private ROMA score does not become a national ovarian screen because you paid for it. It still needs the ultrasound, the history and, on Ultimate, the MRI and the gynaecology option if you booked it.

HE4 can rise for non-cancer reasons. CA-125 can rise with endometriosis, fibroids, menstruation and other inflammation. MRI can show an ovarian cyst that was never going to matter. None of those findings is a diagnosis or an all-clear. Imaging still matters because markers do not see structure, and structure still needs chemistry and an examination in the same conversation.

Ultimate also carries CEA, and PSA for men from 40, because it includes Elite's bloods. The MRI does not make those markers more diagnostic. It gives the doctor another picture to put beside them. A clear MRI is not a cancer all-clear. A raised marker with a quiet scan is still a marker that needs a plan.

Why a flag is not a diagnosis, and a normal result is not a screen

Laboratories mark results against a reference range. A flag means look again, not that you have cancer. A result inside range means that test, on that day, did not show that abnormality, which is not the same as every tissue being free of disease. That is the laboratory limitation NICE is circling when it keeps these tests inside pathways rather than on a poster.

Choose the Ultimate Health MOT only if the MRI protocol plus those extra ovarian markers is the question you brought. Choose an organ package from the cancer screening list if the question is bowel, breast, prostate or lung, because FIT, mammography, prostate MRI and low-dose CT are different instruments from CEA or PSA. Keep the NHS invitations you already receive. A private marker panel does not replace them.

New, severe or worsening symptoms still belong with a GP or urgent assessment. Use 999 or A&E for emergencies. NICE NG12 is a symptom guideline. Screening markers are for people who feel well enough to be screened. Mixing those jobs is how a raised CA-125 on a quiet Tuesday becomes a delayed pathway.

The FAQ covers what happens if something is found: explanation, referral letters, and a doctor who already has the examination. That safety net is part of the MOT. A printed marker without a review is how people email a GP at midnight.

Tips and tricks

• Read the parent article first if you are still asking whether any blood test can detect cancer, then come back here if the live question is the Elite or Ultimate panel.
• Name the marker you care about, and name the picture that would have to sit beside it.
• CEA without a bowel question is a weak reason to book.
• CA-125 without pelvic imaging is a weaker one.
• Say if you smoke, because CEA moves with it.
• Mention an enlarged prostate, a recent urine infection or yesterday's cycle ride, because PSA moves too, and say if you are on your period, or have endometriosis or fibroids, since all of those can shift CA-125.
• Bring previous marker results so a flag can be read as a trend rather than a one-off.
• Fast for a minimum of four hours on Elite and Ultimate, continue regular medicines unless told otherwise, and leave time for the review.
• Ask what happens if a marker is raised.
• Repeating, watching, adding a scan or referring are medical decisions, not extras you have to invent.

Things to avoid

• Do not treat CEA, PSA, CA-125, HE4 or ROMA as a cancer screen, a diagnosis or an all-clear.
• Do not book markers because a longer blood list sounds thorough.
• Do not skip ultrasound, a smear, a mammogram, a FIT kit or a GP visit because a marker was ordinary.
• Do not use a MOT marker panel as a quieter way of avoiding cancer screening of a named organ.
• Do not collect standalone test names from a laboratory menu and call that a MOT. Those individual SKUs stay on blood.london.
• Do not sit on bloating, urinary symptoms, rectal bleeding or a new lump because a screening date includes a protein. That needs a GP or urgent pathway.
• If markers plus imaging are the question, review Elite on the Elite Health MOT page, or contact The Health Screening Clinic on 020 7183 7056.

If a marker comes back raised, what happens after a Health MOT flags something explains the next step.

Frequently asked questions

Are tumour markers a cancer screen?

No. They are clues inside a doctor-led MOT from Elite. NICE NG12 uses PSA and CA125 in symptom-led pathways, not as general cancer tests. The UK NSC has not recommended a general cancer blood test.

Which markers sit on Elite?

CEA for everyone, PSA for men aged 40 and over, and CA-125 for women. They are read with examination and sex-specific ultrasound, not as lone numbers.

What does Ultimate add?

For women, HE4, CA-125 and a ROMA score, on top of the MRI protocol. ROMA is a calculation, not a verdict. NICE has not recommended routine NHS adoption of ROMA for referral decisions.

If a marker is raised, do I have cancer?

No. A flag is not a diagnosis. Smoking, inflammation, benign prostate enlargement, cysts and other non-cancer causes can lift markers. The doctor who examined you decides whether to repeat, watch, image or refer.

If a marker is normal, am I clear?

No. Markers miss disease as well as over-flag it. Imaging and examination still have to be read. Get new symptoms checked even after a reassuring report.

Can I just order the named tests without a MOT?

Standalone laboratory lists of that kind sit on blood.london. A MOT is a consultation, examination, bloods and a review, with imaging from Elite. It is not a SKU catalogue.

I have a new symptom. Should I book markers?

No. New, severe or worsening symptoms need a GP or urgent assessment, not a preventative panel. Use 999 or A&E for emergencies.
