How are accelerators used in cancer treatment?

Accelerators are used in cancer treatment to deliver high-energy radiation to destroy cancer cells.

Accelerators, also known as particle accelerators, produce high-energy beams of charged particles, such as protons or electrons, which can be directed at cancerous tumours. These beams can penetrate deep into the body and damage the DNA of cancer cells, causing them to die.

One type of accelerator used in cancer treatment is the linear accelerator (LINAC), which produces high-energy X-rays or electrons. These beams are carefully targeted at the tumour, while minimizing damage to surrounding healthy tissue. Another type of accelerator is the cyclotron, which produces beams of protons or other charged particles that can be used to treat certain types of cancer.

Accelerators are also used in a technique called intensity-modulated radiation therapy (IMRT), which allows for precise targeting of radiation to the tumour while sparing nearby healthy tissue. This is achieved by varying the intensity of the radiation beam as it is delivered, allowing for a more tailored treatment plan.

Overall, accelerators have revolutionized cancer treatment by providing a powerful tool for delivering high-energy radiation to destroy cancer cells while minimizing damage to healthy tissue.
