Throat Cancer?

Hello. I smoke, unfortunately. It's a habit I hope I don't keep around much longer. But I've got some questions...


I quit smoking about a year and a half ago, and I didn't smoke for long befor I quit. It may have been a couple of months. Recently, I picked it up again. I usually wont smoke unless I feel like it's a complete urge of stress, the maximum I will have in one day is 3. 4 on a horrible day. Sometimes I will go a day or so without any. It's only been about 3 weeks since I started up again, and my throat is a little bit scratchy. I also have a cough, but it's one that hasn't completely gone away since I was sick about a month ago. Since I'm a singer and a musician, I'm extremely paranoid. I know being as paranoid as I am I shouldn't be smoking at all, especially since I'm a singer. But sometimes I just don't know how to deal with stress, and when I get an urge for a cigarette I go for it. Like I said, I'm nowhere near a chain smoker. I'll smoke one or two a day usually, and can stretch a pack out for 2-3 weeks.

I just wanted to see if anyone thinks my scratchy throat could be cancer related? I was thinking if anything I may be coming down with some Bronchitis, because usually a little bit of phlegm will come. Is it possible for me to have any type of cancer related things in a 3 week time period of smoking? The last thing I want is my voice box taken out..
