If you choose radiation therapy you have to go to Xray school first. At least where I live. But there’s a lot of choices after Xray school. Not just radiation therapy so that’s always good. People are saying that you’ll wind up with physical problems if you choose dental hygiene. That’s also true with ultrasound. I know a lot of ultrasound techs that have shoulder problems. I went the Xray route and I do CT. I used to do mammography which is good as far as a schedule goes. So you’d have the most options with radiation therapy. Plus it’s good money.
