Can Lung Cancer Be Detected By Blood Tests
Low dose CT: The national lung screening trial (new england journal of medicine) showed that screening chest ct in high risk patients (heavy smokers and older patients) reduced deaths from lung cancer by 20% compared to patients screened with plain x-ray alone. There will soon be specific guidelines on exactly who should under go routine chest ct screening. ...Read moreSee 2 more doctor answers
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
Doctors said that my shortness of breath and back pain is anxiety after blood tests and chest xray in Dec. But I think lung cancer, chances?
Are there any blood tests or tests other then biopsy of a nodule that can identify presence of cancer anywhere in body or lungs?
No: The reason for this is that cancer is not 'other', it is 'us'. While cancers may produce substances that are ordinarily produced only before birth (carcinoembryonic antigen, alpha-fetoprotein), these aren't sensitive or specific enough to to make biopsy unnecessary. Anyone telling you they have a reliable blood test to rule cancer in/out isn't offering evidence-based medicine. ...Read more
If a blood test is done and there is no detection of cancer, is it concluded that cancer is in remission? The type of cancer is lung cancer
Discuss...: Your question is not exactly clear. "remission" is a term used to describe cancer that was diagnosed and after treatment or in unusual cases "spontaneously" is no longer clinically present. The "blood tests" currently marketed are used to "find" (screen) cancer. Tests like "early cdt" are generally inaccurate if you have already had a cancer. Not used to diagnose "remission". ...Read moreSee 1 more doctor answer
I am 39 f. I had a early cdt lung cancer blood test. I am a ex smoker. Quit 2yrs ago. My magea4 came back positive. Ct of chest clear. Investigate?
Male, 21.Er for chest pain.Had ekg, blood test and chest xrays. Everything came out normal.Doubt its my heart.Are xrays enough to rule out lung cancer?
For you - yes: The incidence of lung cancer for someone 21 years of age is essentially zero. I remember reading some where that the risk of a 30 y/o person dying from lung cancer over the next 10 years is 0. Chest xrays are an excellent screening tool. They will miss some small percentage of lesions because of size and/or location. The most important thing you can do is stop or never smoke. ...Read moreSee 1 more doctor answer
How concerned should I be if one of the blood test for early cdt lung cancer came back slightly elevated? It was the mage 4. Ct was clear
There is no: Approved blood test for early detection of lung cancer. Ct's are approved for smokers and ex-smokers over 55. So, getting a blood test that scares you and then an expensive ct scan that is negative contributes to raising heath care costs and benefiting no one. Get a second opinion from a doctor that focuses on you, your benefit and not unproven expensive tests. ...Read moreSee 1 more doctor answer
I don't smoke. I have had a mild dry cough for past 3 weeks . Blood test and chest xray shows normal .No chest pain. Could it be lung cancer?Im worried
Cough: In general, a symptom of coughing can first be addressed by over the counter measures. Cough specific syrups or tablets are readily available. Decongestant medicines can help if the cough is related to sinus drainage. Giving the cough ample time to clear is advisable (up to 6 weeks) but if you develop fevers, shortness of breath, chest pains, or bloody sputum, then it is time to see the doctor. ...Read more
