What is Proton Therapy?
As proton beams pass through the human body, they release most of their energy at the targeted position to destroy tumor DNA, while depositing minimal energy along their path, with no exit dose beyond the tumor.
This is made possible by protons' property called the "Bragg peak", where energy is minimal until a very narrow peak, then drops to zero. This dramatically higher precision increases likelihood of curing tumors while reducing toxicity and enhancing quality of life.
The Bragg Peak Advantage
Conventional Radiation
• Energy deposited throughout the path
• Damages healthy tissue before and after tumor
• Significant exit dose beyond target
Proton Therapy
• Minimal energy until target reached
• Maximum energy delivered at tumor site
• Zero exit dose beyond tumor
Precision Targeting
Pencil beam scanning delivers treatment to the precise depth and shape of tumors
Organ Protection
Minimal damage to critical organs and healthy tissues surrounding tumors
Better Outcomes
Improved long-term survival rates and enhanced quality of life
Proton Therapy Advantages
Particularly valuable for tumors with critical organ tissues surrounding them, offering superior outcomes with minimal side effects.
Higher Cure Rates
Dramatically higher precision increases likelihood of curing tumors
Reduced Toxicity
Fewer side effects compared to conventional radiotherapy
Quality of Life
Enhanced quality of life during and after treatment
Long-term Survival
Improved long-term survival rates for certain tumor types
