[|Human|] I have had a dry cough since I had smoke inhalation from a smoldering fuse box (no fire) back in March of 2012. I was diagnosed with Bronchitis and given an inhaler. I still have the cough, wheezing, tightness but I also had a scope done on my Larynx back in 2011 and Im a prime candidate for Cancer as the one side is extremely enlarged. My main question is (which I can locate online) what kind of cough is associated with Larynx Cancer? Yes I do smoke but have never had a cough until I had the smoke inhalation. Any explanation of what kind of cough is associated with my previous question would be greatly appreciated. However, if its not that then the other question would be, how long does it take for smoke inhalation to clear the lungs? Im having difficulty sleeping as I wake up every 2-4 hours with this dreaded cough.
[|AI|]  Hello dear thanks for query at ChatDoctorsymptoms in larynx cancer depends up on area of the larynx involved.larynx divided into three parts supra glottis, glottis and sub glottis, symptoms vary according to area involved.supra glottis: often silent, hoarseness of voice is late symptom. Throat pain, dysphagia and ear pain are common symptoms. Glottic : hoarseness of voice is early symptom, also produce strider. Sub glottis cancer: earliest symptom is strider, hoarseness is late feature. Nature of cough may not determine the location. Smoke inhalation may take years to clear from lungs, and it also has long term complication and adverse side effects. Cough during sleep and awakening in your case might be due to bronchitis. Your diagnosed with bronchitis, so all symptoms might be related to it. If you still have strong suspicion of cancer visit doctor get larynx examined and radiological investigation like x-ray and ct scan might be helpful in your case. Regards
