Hi Chicago and no I can't say that I've ever heard of that but honestly not overly familiar with cancer either. I quit smoking so I come and ck the boards here.
But I will tell you one thing - please do not worry about anything. Just pray and I will pray for you as well because worrying will only make you feel worse.
I get sinus infections and have coughed blood up before so it could be a number of things and nothing serious at all. Plus you're very young to have anything like that wrong. Do you know if it cancer runs in your immediate family?
Have faith chicago and no worries
Keep me posted - if I don't get bk to you here (in case I forget - sometimes I post on too many threads) you can find me on the smoking cessation board.
