Employment of radiation therapists is expected to grow by 20 percent between 2010 and 2020, faster than the average for all occupations. However, because it is a small occupation, the fast growth will result in only about 3,400 new jobs over the 10-year period.
The risk of cancer increases as people age, so an aging population will increase demand for radiation therapists. Early diagnosis and the development of more sophisticated treatment techniques will also increase employment.
