What is Proton Therapy
Radiation that stops exactly where the tumour ends.
Proton therapy is an advanced form of external beam radiation that uses positively charged particles (protons) instead of the X-rays used in conventional radiation. The unique physics property of protons — known as the Bragg peak — means they deposit most of their destructive energy at a precise depth inside the body, then stop. Tissue beyond the tumour receives almost no radiation dose.
According to the National Cancer Institute ↗, this precision makes proton therapy especially valuable for tumours located near critical structures — the brain stem, spinal cord, eye, heart — and for pediatric patients, where reducing radiation to developing tissue can dramatically lower the risk of secondary cancers later in life.
India's Apollo Proton Cancer Centre (APCC) in Chennai, the first proton facility in South Asia and the Middle East, uses the same Pencil Beam Scanning and IMPT technology as the top US and European centres — at a fraction of the cost. Get a free expert second opinion →
1
Stops at the tumour — no exit dose into healthy tissue beyond the target.
2
Spares critical structures — heart, lungs, brain stem, spinal cord receive minimal dose.
3
Ideal for children — significantly reduces risk of secondary cancers and developmental side effects.
4
Enables re-irradiation — safer option when conventional radiation has already been given.
