Does radiation therapy reduce side effects?
This results in less healthy tissues and organs receiving unnecessary radiation thereby reducing unwanted complications and side effects. Standard radiation therapy utilizes x-rays which deposits the majority of the radiation dose immediately upon entering the body while traveling to the tumor.
Do cancer cells repair molecular damage?
While both normal and cancerous cells go through this repair process, a cancer cell’s ability to repair molecular injury is frequently inferior. As a result, cancer cells sustain more permanent damage and subsequent cell death than occurs in the normal cell population.

Does proton therapy damage tissue?
Proton therapy accurately targets very specific locations, which may result in less damage to surrounding tissues. Conventional radiation therapy is less targeted, and more "normal" cells in the region of a tumor may be damaged. 3 .
How do proton beams work?
How does proton therapy work? 1 The proton begins its journey at the ion source. Within fractions of a second, hydrogen atoms are separated into negatively charged electrons and positively charged protons. 2 The protons are injected via a vacuum tube into a linear accelerator and in only a few microseconds, the protons’ energy reaches 7 million electron volts. 3 Proton beams stay in the vacuum tube as they enter the synchrotron, where acceleration increases their energy to a total of 70 million to 250 million electron volts, enough to place them at any depth within the patient’s body. 4 After leaving the synchrotron, the protons move through a beam-transport system comprised of a series of magnets that shape, focus and direct the proton beam to the appropriate treatment room. 5 To ensure that each patient receives the prescribed treatment safely and efficiently, the facility is controlled by a network of computers and safety systems. The gantry can revolve 360 degrees, allowing the beam to be delivered at any angle. 6 As protons come through the nozzle, a custom-made device (the aperture) shapes the beam of protons, and another custom-made device (the compensator) shapes the protons into three dimensions, delivering them to the depth of the tumor. 7 At maximum energy, a proton beam travels 125,000 miles per second, which is equivalent to the two-thirds the speed of light. 8 From the hydrogen canister to the patient, a proton typically travels 313,000 miles.
What is the advantage of proton beam therapy?
The advantage of proton therapy (also called proton beam therapy) is that the physician can control where the proton releases the bulk of its cancer-fighting energy. As the protons move through the body, they slow down and interact with electrons, and release energy. The point where the highest energy release occurs is the “Bragg peak.”.

What is the accelerating device that takes protons stripped from hydrogen gas and accelerates them to approximately 2/3 speed of
Cyclotron. The cyclotron is an accelerating device that takes protons stripped from hydrogen gas and accelerates them to approximately 2/3 speed of light. It uses static magnets and Radio Frequency (RF) to accelerate the proton outwards from the centre of the cyclotron in a circular fashion.

Once the proton beam has left the cyclotron, it will encounter the Energy selection system (ESS). The ESS is used to change the energy of the proton beam to align with the depth of the tumour within the patient’s body. The energies range from 70Mev to 230MeV. The ESS is made up of mechanical carbon wedges that are driven into the proton beam.
