Veterans Affairs Lung Cancer Surgery Or Stereotactic Radiotherapy
Recruiting
Patients with stage I non-small cell lung cancer have been historically treated with surgery whenever they are fit for an operation. However, an alternative treatment known as stereotactic radiotherapy now appears to offer an equally effective alternative. Doctors believe both are good treatments and are therefore conducting this study to determine if one may be possibly better than the other.
