[|Human|] I have smoked cigarettes for years and now when I smoke I get headaches, throat pain, swelling in the throat, acid reflux, makes me very tired. I stopped smoking for a few days and felt better.  I have been smoking again and the problems are back. I know I need to see a Dr. My question is do I already have cancer if I have symptoms like this from smoking?
[|AI|]  Hello & Welcome to Chat Doctor, I had gone through your case and I found it might be due to over smoking which create gastritis due to which all symptoms you have mentioned is occur. For conformation of cancer you need to go for further investigation like biopsy of throat scrap and Ct Of Abdomen. But I am sure this will be only gastritis. Better for you to quit the smoking. Take antacid, multivitamin and proper regular diet to improve your fitness. Hope my answer will be effective for you. Thanks & regards: Chat Doctor.
