Totally individual question and depends on many factors. But two days ago when I went in to get my mask adjusted we were sitting in the waiting room. The mask is designed to hold you in place on the table so that you will not move as the radiation is happening. The technican came out and because I was the first person he saw he looked me up and down. I could see he decided I wasn’t who he was looking for. In a moment he looked over the whole room and said “Is Michael Rees here?”. This made me feel good- I took it to mean I was a person who didn’t look like he had cancer.
