I think it is very normal to associate any illness with cancer recurrence. Every time I had a sore throat or cold especially during the time when the treatment was just over for a short while, I would wonder if cancer relapsed or not. What I did would be to get an ENT for a thorough check as soon as possible. Just worrying can't keep the mind in peace. In Hong Kong, medical service is always available even during holidays and I wouldn't want to wait.
