56/m - clear chest X-ray 2 months ago but still got some blood in sputum while clearing throat. Slight loss in weight. Is this lung cancer (ex-smoker)?

56/m - clear chest X-ray 2 months ago but still got some blood in sputum while clearing throat. Slight loss in weight. Is this lung cancer (ex-smoker)?

Rexray: Just because X-ray was negative 2 months ago does not mean it still is negative or originally misread. Because lesion was very small. If hemoptysis (blood in sputum)continues then further investigation including bronchoscopy should be performed. Other causes of hemoptysis include chronic bronchitis. ...Read more

You NEED to stop: Worrying. It will stress you out more. Get a second opinion if you are still not convinced.Cough is all good, it is protective and a defense mechanism against aspirations. Take proper medications for whatever is causing the cough. Need more history and you need to be examined. Colds and allergies are very common causes for lingering coughing spells. Take charge for better quality of life. ...Read more

I've had a cough for a week or so. Dry and wet cough about 12x a day. Could this be lung cancer? I had a clear chest X-ray in july. 36yo smoker.

Maybe: The typical warning sign for lung cancer is coughing up blood, although this is not always present in people with lung cancer. The most important consideration is whether or not you smoke. You need to stop smoking right away, permanently, and live a long, healthy, cancer-free life. If you stop smoking now, your risk of lung cancer is greatly reduced. ...Read more

Anxiety: You are a 32 y.o. man with no history of smoking and no pulmonary history whose only medical history is generalized anxiety disorder. Based on what you have told us, it is more likely this is part of your anxiety. Repeated ionizing radiation such as unnecessary chest x-rays is not without its own risk. Hypochondria or M√ľnchausen may be at play here. Discuss with your therapist. ...Read more

Cancer phobia: If your had bone pain from metastatic cancer, this would show up on your x-rays. You also realize that you're young to have lung cancer, and that your cough is very likely due to your smoking unless your physician has found another cause such as a tendency to asthma. This would be a great time to stop smoking because the next scare may be real & get with your physician about dealing with fear. ...Read more

25 yr old, 9 year smoking history, bloody boogers and when make myself cough or clear throat, I have isolated blood streak lung cancer? ?

Probably not....: Blood-tinged sputum is typically caused by bronchitis, which is an infection in the lung airways. You could also have post-nasal drip and the blood is from the nose or sinuses. You need to quit smoking ASAP as this is contributing to inflammation in the airways which predisposes you to acute bronchitis. See your doctor for diagnosis/treatment and to help you quit smoking! ...Read more

No pleural mass in chest CT scan, clear pleural exudate (lab results say it is exudate not transudate).No fever or cough. Can we rule out lung cancer?

Not enough info....: With the information provided, lung cancer cannot be ruled out. Need to know if any mass or abnormality was seen on the chest CT scan. An exudative pleural effusion could be due to many things including pneumonia, cancer, etc. A sample of the fluid should be sent for a variety of cultures as well as looked at for malignant cells. More testing is definitely needed for a diagnosis to be made! ...Read more

Lung Cancer unlikely: You are too young to have lung Cancer. I would advise you to follow up with your doctor as to how he/she should monitor you further. It will partly depend on your future symptoms. If there is any more coughing with blood, then additional testing would be necessary. Otherwise you should do fine. But do not smoke! ...Read more

Male 21. Non smoker active lifestyle. I seem to be getting frequent colds with little cough about every other month. How likely is lung cancer?

Essentially zero: Although there is some data suggesting that lung cancer occurs at a bit younger age in never-smokers compared with smokers, in the absence of (for instance) immune system deficiency or underlying lung disease or the presence of cancer elsewhere in the body which could spread to the lungs, the likelihood of lung cancer at age 21 in an otherwise healthy non-smoker is virtually zero. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. 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

Cough benefits the host by reducing load and benefits the pathogen which may then spread via aerosol. ...Read more
