What is radiation therapy?


Radiation therapy uses high-energy radiation to shrink tumors and kill cancer cells (1). X-rays, gamma rays, and charged particles are types of radiation used for cancer treatment.

The radiation may be delivered by a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy, also called brachytherapy).

Systemic radiation therapy uses radioactive substances, such as radioactive iodine, that travel in the blood to kill cancer cells.

About half of all cancer patients receive some type of radiation therapy sometime during the course of their treatment.

放射線療法とは何か?


放射線療法は腫瘍を収縮させ、癌細胞(1)を殺すために高エネルギー放射線を使います。エックス線、ガンマ線、そして荷電粒子といった種類の放射線が癌治療に用いられます。

放射線は体の外の機械により照射される(体外照射療法)こともあれば、体内の癌細胞の近くに設置した放射性物質により照射される(内部放射線療法、または近接照射療法と呼ばれる)こともあります。

全身放射線療法は放射性ヨウ素のような放射性物質を使い、血液中を巡らせることにより癌細胞を殺します。

約半数の癌患者が治療の過程において放射線療法を受けます。
