Thanks, Chris and Parazapper. Here is the rest of the story

I doubt that the poster suggested radiotherapy for any reason other than as an excuse to post spam.  The original post contained the single word "radiotherapy", as it appears now, plus a link to an electronic cigarette sales site I removed.  I probably should have just hidden the post entirely, but figured since it had been up and had a few views that perhaps someone would come along to rebut it.  Thanks to the both of you.
