Understanding the science behind cancer treatment can make a world of difference🎗️

Traditional radiotherapy often impacts healthy tissues and increases long term side effects, but Proton Beam Therapy offers a more precise alternative. This advanced treatment works by harnessing the energy of protons.

Here’s how it works:
* Powerful Acceleration: A particle accelerator speeds up protons to nearly the speed of light.
* Focused Precision: These protons are delivered as a finely tuned beam, specifically designed to focus directly and precisely on the tumor.
* Dedicated Care: At our facility, this targeted beam is delivered in one of our four specialised treatment rooms, ensuring each patient receives the highest level of care.

By focusing the radiation dose exactly where it’s needed, Proton Beam Therapy helps to spare surrounding healthy organs and tissues, significantly reducing side effects.

2026: A New Standard for Cancer Care 🧬

Towards the end of 2025, a landmark Phase III trial in The Lancet officially changed the conversation around Proton Beam Therapy (PBT). PBT is now confirmed as a new standard of care for head and neck cancers.

For the first time, this major study proves we can improve survival rates while simultaneously reducing life-altering side effects.

The Results:

✅ 10% increase in 5-year overall survival. ✅ 42% reduction in the hazard of death. ✅ Fewer complications: Better swallowing, less dry mouth, and reduced feeding tube dependence.

At Proton International London, our Chief Medical Officer (CMO) Dr. J.W. Snider served as a primary investigator for this global trial. We are proud to bring this world-leading, Level 1 evidence to our patients today.

In 2026, precision isn’t just an option—it’s the benchmark.

This year, we continue to protect what matters.

Steve’s experience with a rare, recurrent, and initially inoperable 38cm tumour highlights the critical need to push for better solutions. His life was transformed by Proton Beam Therapy (PBT), which successfully shrank the mass while protecting his only remaining kidney post surgery.

“You’ve got to be positive... If you stay positive, you have a chance.”

If you are facing a complex or rare cancer diagnosis, don’t settle for uncertainty.

* Ask about PBT: Inquire with your specialist about the suitability of Proton Beam Therapy for your tumour.
* Seek a Second Opinion: You have the right to explore all options. Proton International London (PIL) offers private consultations for a second opinion on complex cancers, including sarcomas.
* Contact PIL Directly: Call 020 4629 3598 or visit our website to inquire about the second opinion process, cost, or to self-refer for a private consultation.

Knowledge is power. Take the step to find the precise care you deserve.

You’ve probably seen both IMRT therapy and Proton Beam Therapy (PBT) mentioned when researching cancer treatment. But a new study has revealed something you shouldn’t miss.

In this latest analysis, our Chief Medical Officer, J.W. Snider, explains the cure rates between IMRT and PBT were the same—but PBT showed a 10% higher survival rate at 5 years. That difference matters when you’re weighing long-term outcomes and quality of life.

Why might this be happening?

Last Friday, we joined University College London Hospitals NHS Foundation Trust in celebrating a wonderful milestone with an equally wonderful little girl.

Meet Seren, the 1,000th patient to receive proton beam therapy at the state-of-the-art centre we share at University College Hospital in London.

Seeing children like Seren able to access this level of targeted care here in the UK shows just how far the service has come since opening its doors in 2021, and reflects the continued commitment by all involved to enabling more patients to benefit from this pioneering treatment.

Wishing Seren and her family all the very best in her recovery.

Seeing children like Seren able to access this level of targeted care here in the UK shows just how far the service has come since opening in 2021. It also reflects the dedication of so many people working to ensure more patients can benefit from this important treatment.

Proton Beam Therapy (PBT) is not just a powerful treatment; it’s the smarter long-term investment in a patient’s health and recovery.

While the initial cost of PBT can be a consideration, new clinical trial results confirm that its reduction in debilitating side effects translates to significant financial and health benefits over time.

Recent trials showed that PBT’s reduced side effects yield an exceptional Quality-Adjusted Life Year (QALY) gain, valued at just $40,000.

This result is game-changing because it falls well below the $100,000 threshold often used to define a highly cost-effective medical intervention.

What this means for patient care:
* Reduced Lifetime Costs: Fewer side effects mean less need for expensive follow-up care and symptom management.
* Faster, Better Recovery: A quicker return to a high quality of life.
* New Standard of Care: This data strongly validates PBT as the high-value treatment the industry needs.

At Proton International London, the UK’s only private PBT centre, we are dedicated to delivering this precise, and protective cancer treatment.

Our Expert Clarifies: Why Proton Therapy is NOT Just Regular Radiation 💡

You’re researching cancer treatments and seeing the term ‘Radiation Therapy’ everywhere. But you need to know the facts!

As our Chief Medical Officer, Dr. J.W. Snider, explains in this exclusive clip from the , understanding the difference between conventional radiation and Proton Beam Therapy (PBT) is key to preserving your quality of life.

PBT’s unique ability to stop at the tumour is a key difference, allowing us to actively protect vital healthy structures—like your swallowing muscles during head and neck treatment.

The Radiation Difference That Could Change Your Treatment

If you or a loved one are exploring cancer treatments, this is the one question you must ask your oncologist:

What is the difference?

Traditional Photon Radiation (X-Rays): Photons enter the body, hit the tumour, and then keep going, exiting the body and depositing a small dose of radiation in the healthy organs and tissue on the other side. This is called the “exit dose.”

Proton Beam Therapy (PBT): Protons are physical particles that can be precisely controlled. Using a phenomenon called the Bragg Peak, the beam delivers its maximum, tumour-killing energy and then stops completely—eliminating the exit dose entirely.

The Bottom Line (Why Precision Matters):
* For Cancers Near Critical Structures: PBT is crucial for tumours near the heart, spine, brain, or eyes, where avoiding the exit dose can drastically reduce long-term side effects.
* For Re-Treatment: Allows doctors to safely re-treat a recurrent tumour by minimising the total lifetime radiation dose to surrounding tissue. 

At Proton International London, our Patient Enquiry Specialists are here to answer every question you may have about proton beam therapy, from how it works to whether it could be suitable for you or a loved one.
