I'm 10 weeks post-surgery and I do think of every bump and sore in my mouth as a cancer reocurrance. I can't tell my family this as they alreay think I'm going to choke to death (my husband listens out for every sound I make, it means I can't always relax when I eat or drink near him). So I agree that it's like having cancer PSTD.
