Thats okay. I have just finished my radiation treatments for throat cancer last week. I will know when I get my scope on the 9th. of next month if I am cancer free for the time being. With throat cancer you generally have a cough, a sore throat for over two weeks, a raspy voice, a hard time swallowing, coughing up blood streaked mucus, a sore in the mouth, or a feeling of having a lump in your throat.
Yes it can be caused by smoking, by GERD, by a virus, by heavy use of alcohol and some poisonous gasses. it more frequently occurs in older people past the age of thirty and mainly in the 40-60 age group. If you ever do get any of the symptons of throat cancer or any cancer please see your doctor.
Good luck and God bless,
