Radiation therapy kills cancer cells with high-energy beams created by sources such as X-rays and protons. Before or after surgery, radiation therapy might be employed.

Radiation works best depending on the stage of lung cancer and several other factors:

  • For starters, concomitant chemoradiation is a choice in the case of limited-stage small-cell lung cancer (SCLC). The first or second cycle of chemotherapy begins after the radiation.
  • Then, individuals with advanced lung cancer or those with limited-stage lung cancer who do not want chemotherapy and radiation combined receive radiation following chemotherapy.
  • It is also a prophylactic measure for the brain to prevent cancer from spreading, as it does in most cases of aggressive small cell lung cancer. For both the restricted stage and the extensive stage of small cell lung cancer, prophylactic cranial radiation is the best option.
  • Finally, it is a palliative treatment that aids in the alleviation of cancer symptoms.

What is the procedure for administering radiation therapy?

External beam radiation therapy (EBRT) is the most frequent type of radiotherapy, which distributes radiation from outside the body and focuses it on the tumor.

Conformal radiation treatment in three dimensions (3D CRT)

This sort of radiation employs one-of-a-kind computer software. It depicts the tumor's exact location as well as its shape.

IMRT (intensity-modulated radiation treatment)- is a type of radiation therapy that is used to

It is a type of 3D therapy that is more advanced. An inverse planning programme is used in this sort of radiation to help provide the therapy with precision and accuracy. The intensity of the beams is controlled to prevent them from hurting neighbouring healthy tissues. This therapy is required for vital structures such as the spinal cord.
