MeierEce, Welcome to our site. Sorry you had to find us, but if this is cancer, you are in the right place to get good info from some that have been there. Are you going to a cancer center? Is the ENT connected to a cancer center? If not, you should go to one ASAP. Given your tobacco use and the tonsil, lump situation, you should consult some experts soon. Don't panic, always remember that until a pathologist says its cancer, it isn't. It can be other things, but just to be prudent go to a center and get it checked out as soon as possible. I wouldn't wait a couple of weeks. Also, I don't believe cancer can be detected through a blood test, so that would not be of use to check for it. Again, not to panic, but if you aren't at a cancer center, I would go to one very soon and have the experts take a look. Keep us posted, OK, and I will add you to my prayers.
