Cancer screening packages in Korea: what to know before adding PET-CT
What Korean 'cancer screening' add-ons contain, what each test can and cannot tell you, and the questions to ask before paying for whole-body imaging.
Korea runs a national screening programme for its own residents covering a short list of common cancers. The packages sold to visitors go well beyond that list. More tests is not the same thing as better screening, and a good centre will say so when you ask.
What the add-ons usually are
| Test | What it looks at | Worth knowing |
|---|---|---|
| Gastroscopy | Oesophagus and stomach | Stomach cancer is common in Korea, so centres are very practised at this |
| Colonoscopy | Large bowel | Finds and removes polyps in the same session; needs bowel preparation |
| Low-dose chest CT | Lungs | Mainly studied in long-term heavy smokers; often finds small nodules that need follow-up scans |
| Mammography / breast ultrasound | Breast | Ultrasound is often added because dense breast tissue makes mammograms harder to read |
| Abdominal ultrasound or CT | Liver, pancreas, kidneys | Incidental cysts are common and usually harmless |
| Tumour markers (blood) | Proteins linked to some cancers | Can be raised for harmless reasons and normal when cancer is present — not a diagnosis either way |
| Whole-body PET-CT | Areas of high metabolic activity | Expensive, involves radiation, and is not part of routine screening guidelines for people without symptoms |
The cost you do not see on the price list
Every test has false positives. The wider the net, the more likely you fly home with a finding that is 'probably nothing, repeat in six months'. For a resident that means another appointment. For a visitor it means finding someone at home willing to follow up another country's scan, or paying for another trip. Before adding a test, ask the centre what happens next if it shows something unclear.
Verify before you rely on this: Package contents, prices and the radiation dose involved differ by hospital, and foreign visitors pay privately outside national health insurance. Ask for the itemised test list and the price of each optional add-on before you book rather than choosing on the day.
Questions worth asking
- Given my age, family history and smoking history, which of these would you recommend — and which would you leave out?
- What is the radiation dose of the CT and PET-CT in this package?
- Who reads the images, and will I get the images themselves as well as the report?
- If something needs a biopsy, can it be done during my stay, and how long does pathology take?
- Will the report be in English, and will a doctor go through it with me?
Practical note: Bring previous scans and reports if you have them. A nodule that is new and a nodule that has been stable for five years look the same on one scan and mean very different things, and the reading doctor can only tell the difference if there is something to compare against.
A clear screening result does not rule out cancer, and an abnormal one does not confirm it. If you have symptoms, you need a diagnostic appointment with a specialist, not a screening package.
Work out the whole trip: open the total cost calculator with 4 nights filled in. That is a planning default, not a schedule — replace it with the dates your own clinic gives you.
