Stereotactic radio surgery is probably better than chemo.
While that may often be the case, I wonder how true that is for cancers other than localized tumors.
In January, I had a lobectomy on my right lung. After recovering from surgery, I had 15 stereo radiation treatments for a separate mass on my left lung.
To finish things off, in case there were some rogue cells "floating around", my oncologist recommended a 4-dose course of chemo. (While it was hardly a pleasant experience, I was blessed to have only had minimal side effects.)
