Cough Due To Cold Or Lung Cancer
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
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
So scared have something like lung cancer, had cough for 7 weeks after cold, not easing. Dr said chest and breathing ok and no other worrying symptom?
MGT: Your risk for lung cancer involves a number of factors including your smoking history, chest imaging findings, and genetic predisposition. If you are experiencing a prolonged cough, a pulmonary function test and chest radiograph may help to determine the next steps. If your chest is clear on exam the likelihood of bronchitis or pneumonia is less. A virtual in box consult can also be arranged. ...Read moreSee 1 more doctor answer
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.

Chronic throat clearing problem (not cough) almost 2 years, but never during sleep, could lung cancer behave this way? Started after a cold, so scared
Not necessarily: If you have a cough that's new or won't go away you definitely should see your primary doc for an evaluation. (if you're coughing up blood, of course you'd want to be seen asap). With your age, if you have a significant smoking hx (>pack/day for 30yrs or more), you may be a candidate for screening chest ct. ...Read moreSee 1 more doctor answer
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
The cough reflex is a protective mechanism that uses muscles in your throat and chest to expel mucous and saliva that may contain pathogens that would otherwise possibly be inhaled via aerosol or to expel pathogens infecting the throat and respiratory system. Cough benefits the host by reducing load and benefits the pathogen which may then spread via aerosol. ...Read more
