There aren't many symptoms of throat cancer. It's most often found in heavy smokers/heavy drinkers. Sometimes it may cause horseness that doesn't go away or a sore throat that keeps coming back. If you have a these symptoms for longer than a week you should get checked out. And if it lasts for months, you should see a specialist. Better to be safe than sorry. It took me a year and a half to get diagnosed, but I was extremely young when I got it, so nobody was really looking for it. I wish you the best of luck.
