I heard last week that CT scan showed a 4cm mass upper anterior lung, probably lining and I had my PET scan this morning. I have to say I am so scared and my mind is working overtime as I've had ringing in my ears for the last few weeks. I don't know if the ringing started when I first had the news there was something wrong but of course I am thinking the worst and thinking cancer of the brain. I'm finding that dealing with the terror is almost harder than dealing with the reality. How do others cope with this fear in these early times and has anyone else had a similar experience?
