I took a early cdt lung blood tests and the P53 autoantibody was the only one slightly elevated what does that mean? Have I got lung cancer?

I took a early cdt lung blood tests and the P53 autoantibody was the only one slightly elevated what does that mean?  Have I got lung cancer?

Nobody knows: These are experimental and nobody knows what various levels mean. These markets are infamous for false positives and I would not get this test on a fishing expedition even if it were free. Without a lung lesion visible on imaging, this information is useless. If you feel well and are not losing weight of coughing up blood, be thankful and forget about it. ...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

Other than chest x-ray, any other ways to look for lung cancer? Blood tests, etc.? Thank you.

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 more

Are there any blood tests or tests other then biopsy of a nodule that can identify presence of cancer anywhere in body or lungs?

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

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 more

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

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 more

The blood test is: Bogus. It is not part of my work up. You are too young to qualify for ct screening. It is too bad you waited to 42 to quit, but it is great that you did. Find another medical group. ...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
