I'm a little ambivalent on this. Sometimes the body says "I don't feel good!". My body says that quite a bit. Mostly (just math) it's something transient. A sore throat is probably not cancer; a bruise is probably not that either. If there's something to be done, then do it. But, don't perseverate about what it could be. You'll drive yourself mad. Telling someone not to worry about something, particularly from a position of authority, when the chances are (again, math) that it's not serious seems a charity. "You're fine, and come back in a week/month if it persists. But, stop worrying." is a fair approach. Nobody wants someone else to worry unnecessarily. It's pointless.
