Proton therapy

What it is

Proton therapy accelerates hydrogen nuclei (protons) and directs them at the tumour. Because protons stop at a set depth, tissue beyond the tumour receives almost no radiation.

Its effect on the cancer is similar to conventional radiation; its strength lies in sparing what surrounds the tumour.

Who it suits

It is used for childhood cancers where a growing body must be protected, tumours next to the eye, brain or spinal cord, head-and-neck cancer, liver cancer, and selected lung and oesophageal cancers. It is also considered when a recurrence has to be re-irradiated.

It is not a standard treatment for cancer that has spread to several organs, or for blood cancers. The remote review answers based on your stage and the tumour's location.

How it proceeds

Simulation and planning take one to two weeks, followed by 10–35 sessions, five days a week. Each session takes about 30 minutes including set-up.

Children may need sedation to stay still, so a paediatric anaesthesia team is on hand. The concierge arranges family accommodation and schedules.

Duration and recovery

Skin changes and fatigue can occur but mostly settle once treatment ends. Most patients can fly home within days of the last session.

Response assessment and follow-up continue remotely once you are home.

Cost

Korean national insurance covers some cancers for residents; international patients pay the hospital's international rate. Because it varies widely by cancer type and number of sessions, the cost is confirmed by quote.

The review fee is credited against your bill when you go ahead with treatment.

In Korea

Korea runs two proton centres, with more due from 2028. Paediatric proton therapy is a long-established field in Korea.

Frequently asked questions

Can children be treated?

Yes. Childhood cancer is one of the main indications. A paediatric anaesthesia team is on hand when sedation is needed, and the concierge helps with family accommodation and schooling.

Which is better, protons or carbon ions?

Neither is better in itself — only better suited. Where sparing healthy tissue comes first, protons are considered; where radiation resistance is the issue, carbon ions. The opinion states which applies to you.

Why is the stay long?

It comes down to the number of sessions: 10–35 at five a week works out at 4–7 weeks. Accommodation is arranged within walking distance of the hospital.
