The first signs or signs of cancer are difficulty swallowing or even a lump felt in your throat.
The lump you feel in your throat would be a tumor which then begins to grow and makes it harder for you to swallow.
If you think you may have throat cancer you should see a doctor right away or go to urgent care or the emergency room and get treated as soon as possible.
If caught early enough the throat cancer can almost always be cured but if left to progress the throat cancer can not be treated or cured and it will lead to death soon after.
Other signs of throat cancer are difficulty swallowing. voice changes, especially hoarseness or not speaking clearly and a sore throat that lasts longer than a week or two or gets worse.
