Radiotherapy is one of the main treatment techniques, which is a cancer treatment method that uses high-energy rays such as X-rays, γ-rays, electron beams, etc. to kill cancer cells or prevent their growth. Radiotherapy destroys the DNA of cancer cells, making them unable to divide and reproduce, so as to achieve the purpose of treating cancer. Approximately 70% of cancer patients need radiotherapy during the process of treating cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the most important means of cancer treatment.
