|---|---|---|---|
| 설명 | X선, γ선의 전자방사선이나 전자선, 양자선, 중성자선 등의 입자방사선을 이용해, 주로 악성 종양 치료를 목적으로 하는 치료법이다. 암세포가 주위의 정상세포보다도 방사선 감수성이 높은 점을 이용하여, 정상세포의 손상을 가능한 한 최소로 억제하면서 암세포를 파괴한다. 사용되는 방사선에는 밀봉소선원에서 나오는 γ선, 직선가속기에서 얻어지는 고에너지 X선과 전자선, 텔레코발트장치에 의한 60Co의 γ선과, 베타트론에 의한 전자선, 사이크로트론에서 얻어지는 양자선, 중성자선 등이 있다. |

|---|---|---|---|
| 설명 | 방사선의 살균효과나 세포를 죽이는 효과를 치료에 이용하는 방법으로, 좁은 의미로 암의 방사선치료를 의미한다. 암에 대한 방사선치료는 암세포를 죽이는데 효과가 큰 베타선을 주로 사용한다. 하지만, 이런 방사선치료는 정상세포에도 큰 영향을 끼쳐 이에 따른 기능의 장애를 가져올 수 있다. 따라서 방사선치료에 있어서는 단지 그 암세포에 대한 작용뿐만 아니라, 정상세포에 대한 작용도 고려하여 시행한다. |
