The nurse was trying to get your husband to quit and instead provided you with an excuse not to quit.

Clearly, her technique is flawed...

I stopped by my radiation center the other day to say hello and bring them up to speed on my latest bout with SCC -- There was a vehicle parked next to me in the parking lot with an overflowing ash tray like I haven't seen in decades -- Don't know how someone could be taking X-ray therapy and keep on smoking (maybe they were getting radiation for something else...).

While I was doing XRT, a fellow was coming in for lung cancer XRT and he REEKED of cigarettes -- I was going to request a change in treatment time to avoid the sickening smell, but for some reason they changed his time.
