What is proton beam therapy?
Proton beam therapy is an advanced form of radiotherapy that uses protons rather than X-rays to treat cancer.
The key advantage lies in how the radiation dose is delivered. Proton therapy allows radiation to stop precisely within the tumour, significantly reducing exit dose to surrounding healthy tissues.
Unlike conventional radiotherapy, proton therapy can:
- Deliver radiation with extreme precision
- Reduce radiation dose to surrounding healthy tissue
- Lower the risk of long-term side effects
- Be especially beneficial in complex or sensitive tumour locations
- Improve quality of life
This makes it particularly valuable for cancers located close to critical structures such as the brainstem, brain, eyes, optic nerves, salivary glands, spinal cord and skull base and in the head and neck.
Why choose Dr Ram for proton beam therapy in the UK?
Choosing the right specialist for proton beam therapy is essential, particularly for complex cancers located near critical structures.
Dr Ram is a highly experienced Consultant Clinical Oncologist with particular expertise in advanced radiotherapy and proton beam therapy for head & neck, brain and skull base tumours and has more than 14 year’s experience in proton beam therapy and completed five advanced Fellowships in Proton beam therapy and Carbon Ion therapy in USA and Europe.
