[|Human|] I smoke ,, and have been for several years now. And just now, I was smoking , my throat started to bleed and I was spitting up blood, I can feel it in my throat, like a sore. The bleeding only left a small amount of blood in my salivia, out of about the 10 times I spit, I saw blood in probably about 6 times out of 10. It has stopped but I am wondering if this could be a sign of throat cancer or something like that?
[|AI|]  Dear Luke, there is a chance that this sign could mean something serious but don't be concerned until you do further diagnostic test. It's important to know do you vomit blood, coughing up blood, or you just noticed it in your saliva. The first one means that you have some serious gastritis, gastric ulcer or esophageal disease. Coughing up blood is also a serious symptom which could be sign of pneumonia, COPD or even cancer so this needs to be ruled out. Blood in the saliva could be seen due to some lesion (ulcer, tumor, gingivitis, teeth disorders) of mouth or pharyngeal mucosa. So depending on what I've just said you should definitely do Castro, pull and ORL examination.  Wish you good health,
