Proton therapy uses high-energy proton beam for cancer treatment. Its game changing efficacy in treating cancer has made it the pinnacle of radiation therapy in the world. Proton therapy has ushered in a new paradigm of clinical excellence and outcomes in cancer treatment. It provides targeted treatment and precision unlike any other radiation treatment.


Proton therapy, also known as Proton Beam Therapy, is an advanced type of external beam Radiation Therapy. In Proton Therapy, surgeons use high-energy proton beams, instead of X-rays, to treat cancer. These high-precision beams irradiate the tumour and destroy it by attacking only the cancer cells.

Proton therapy is considered one of the most advanced forms of radiation therapy in the world. This can be attributed to the high levels of precision that the procedure offers, as compared to other treatment options. While X-ray beams are effective in controlling many cancers, they also deliver an ‘exit dose’ along the path beam. This exposes not just the targeted tumour to the radiation, but also the nearby healthy tissues. This exit dose is a cause of concern as the damage to the normal tissue or organs can affect the patient’s quality of life post-treatment.

In comparison, proton beams target the tumour with sub-millimetre accuracy, leaving the nearby tissues unharmed. Protons deliver the bulk of their energy at a precise focal point, designated by the surgeon. As the protons move through their path beam in the body, they slow down and interact with electrons, and release energy. The point where most energy is released is called the Braggs Peak. The Braggs Peak’s location can be accurately set by the surgeon to conform to the shape and depth of a tumour. The nearby healthy tissues and organs are spared, making Proton Therapy the most precise and effective treatment procedure ever.

The Power of Proteus Plus

At Apollo Proton Cancer Centre, we offer patients the most advanced multi-room Proton Beam Therapy. To match the high international standards of Proton Beam centres in the world, APCC is powered by PROTEUS®PLUS – a unique proton therapy solution to tackle even the most complex tumours. PROTEUS®PLUS is equipped with a wide range of cutting-edge features that are useful to deliver high-precision solutions to patients.

The PROTEUS®PLUS is configured for excellence. It enables surgeons to perform highly innovative treatment methods like Image-Guided Intensity Modulated Proton Therapy (IMPT). With IMPT, radiation oncologists can accurately set the precision, depth and intensity of a proton beam as per the contours of a tumour, sparing nearby healthy tissues and organs. PROTEUS®PLUS enables IMPT by combining the fine precision of the Pencil Beam Scanning (PBS) delivery mode with the accuracy of 3D Cone-Beam Computed Tomography (CBCT) imaging and the adaptive capacity of In-room CT.

Ambient Experience

Great design is not just about a product, it is about how it works and how empathetic it is towards the user. Our standards have always been uncompromising when it comes to patient experience, and so it is no surprise that the equipment we use for Proton Beam Therapy makes customer comfort and convenience a great priority. In partnership with Phillips, the world leaders in ambient lighting, our centre has the ground-breaking Ambient Experience.

Based on insights from Proton patients, our equipment uses dynamic lighting, projection and sound to transform a cold, impersonal environment into one that is soothing and comfortable. The Ambient Experience not only has a positive impact on patients and staff, but has shown proven results in improving workflows and augmenting throughput.
