[|Human|] Im 16, around 50kg and around 170cm and i dont smoke. i spat out bloody phlegm around 3 hours ago, but i didnt cough it up. I didnt have any symptoms of pnuemonia or anything similar to that. I dont have any other lung cancer symptoms. And the blood to saliva+phlegm ratio was about 1:3. However i do have a habit of clearing my throat 3 times a minute, but ive never had bloody phlegm before, and this habit stayed with me for years now. Whats wrong with me???? i hope i dont have cancer :(
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Symptoms of lung cancer are cough, bleeding in sputum, weight loss, fever, mass in lung etc. At age of 16 chance of lung cancer is almost nil.  So don't worry about that.  You may have some upper respiratory tract infection or other problems.  Consult your doctor and take treatment accordingly.  Don't worry about cancer. Just be relaxed. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
