Not likely: If you have a normal chest x-ray, then you are not likely to have lung cancer, at least not an obvious tumor which could explain your persistent cough. Yet if you cough persists, you need an ongoing medical evaluation and treatment to control it. Sometimes it can be a symptom of asthma or acid reflux. So go see your doctor again till the cause has been found and treated. ...Read more

Pain in upper right back. Slight cough for 2 months. 2 xrays and bloods. All fine. Highly anxious now. Could I have lung cancer. ?

Pain in upper right back. Slight cough for 2 months. 2 xrays and bloods. All fine. Highly anxious now. Could I have lung cancer. ?

Stop worrying: I can't promise you don't have a tiny lung cancer. You're a never-smoker, you're young, you have a "slight cough" (been checked for cough-variant asthma?), and most back pain never gets a hard diagnosis.

Work with ur dr to find real causes. ...Read more

Scared I've got lung cancer cough and cold for a while today coughed and there was a tiny speech of blood, after blew my nose and there was blood ther?

Suggestions: Inflammation in the airway ( either upper or lower ) may be associated with small amounts of bleeding. If your nose is bleeding this can appear in the post nasal drainage. If you are a smoker in particular, I would suggest sputum cytologies. During a viral illness, your asthma may worsen, requiring an adjustment of your medications.

At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
