Radiation therapy--past and future

Not long ago, cancer was generally looked on as a lethal disease. In the last decades, recovery chances for various forms of cancer have increased spectacularly. And research is still going on. Various new therapeutical techniques have been implemented recently or will be in the near future. In my paper, I will first briefly mention some achievements of the past 25 years. Then I will discuss some methods that have been developed recently, or that are still in an experimental stage. I will also concentrate on aspects that are of interest to the radiographer, and that may influence daily routine and workload.
