Also it seems to me that until a biopsy of the mass is done to show for sure if it's cancer or not I wouldn't worry about it. Worry and waiting are two of the main culprits that those of us with cancer have to deal with. Have your doc do a biopsy if you're that concerned but try not to worry excessively about the results. Chances are pretty good that you have nothing to be concerned about and you have found the best place POSSIBLE to bring those concerns if it turns out otherwise. Hopefully you won't have to come back, but we're here for you if/when you need.
I noticed from another post of yours that you were a smoker-thus the paranoia, right? I'm right there with ya, my friend! Feel free to post any further concerns or suspicions but get on and enjoy your life!
