I'm so-o-o-o glad you were able to quite smoking! I've never smoked but I've lost friends and other loved ones to smoking. I can't really know, but I have seen how hard it is to quit. It's good that you took steps to find out for sure what has been causing your problems these past 6 weeks. The biopsy today should let you know one way or the other what it is. Until you find out for sure, please try to think about all the good things mentioned above instead of the negative possibilities. Once you find out, you will be more in control of what happens to you, and can start doing whatever is necessary to get better. Stay with us and let us know what happens with you. We really do care.
