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 (Definition)

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

I'm 43 non smoker just worried about lung cancer with a 3 on sed blood test CBC test good X-ray was clear with chest pain is lung cancer a worry?

I'm 43 non smoker just worried about lung cancer with a 3 on sed blood test CBC test good X-ray was clear with chest pain is lung cancer a worry?

Are you: referring to the ESR(erythrocyte sedimentation rate)? A value of 3 mm/hr is normal. Even if it was elevated, the ESR is a very nonspecific indicator of inflammation and other pathology, and could be elevated for numerous reasons. You are relatively young and a non smoker, the chances that your pain is due to lung cancer are extremely miniscule. ...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

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

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

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?

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 more

Should i be concerned about a positive mage a 4 test? Mage= melenoma antigen gene? I had early cdt lung cancer blood test. Ct of lungs clear

Should i be concerned about a positive mage a 4 test? Mage= melenoma antigen gene? I had early cdt lung cancer blood test. Ct of lungs clear

MAGE A4 Tesring : The mage a4 antigen, even though it was named the melanoma associated antigen, is a non-specific antigen that has been linked to a wide variety of tumors. It's efficacy is still being debated as a stand alone predictor. Your physician should investigate and rule out the most likely malignancies for your age and family history, including early breast and oral cancer, as well as others less likely. ...Read more

Upper back pain since last may.Dr ordered CT of chest. It was clear. Also took early cdt lung cancer blood test the magea4 was positive. Worry?

Upper back pain since last may.Dr ordered CT of chest. It was clear. Also took early cdt lung cancer blood test the magea4 was positive. Worry?

What for?: Mage a4 is not an approved screening test for lung cancer, was this done as part of a research trial? Lung cancer in a 39 year old with a clean ct chest would be very unusual, and in a person with very low risk of cancer any screening test that is positive is most likely a false positive. I would suggest discussing the purpose of the test and results with the doctor who ordered it! ...Read more

Went to the ER with chest and entire back pain. EKG fine. Blood tests fine. Said "I don't know what's wrong." Worried it's cancer or heart problems. ?

Went to the ER with chest and entire back pain. EKG fine. Blood tests fine. Said "I don't know what's wrong." Worried it's cancer or heart problems. ?

Likely neither: It is not likely that you have heart disease or cancer. However, ER is not the right place for continuing healthcare. Please find a primary care provider and follow her/his advise about diet, exercise and healthy habits. Do not use tobacco or alcohol. ...Read more

If blood tests came back good could oral cancer still be a posibility. no lesions but sore areas gums and tongue, hard to swallow and chest hurts?

If blood tests came back good could oral cancer still be a posibility.  no lesions but sore areas gums and tongue, hard to swallow and chest hurts?

It depends: Blood tests typically remain unchanged in most cancers other than blood cancer. But it is the examination of the oral cavity which is more important to determine the cause of your mouth sores.Most such situations are not due to oral cancer.it could simply be Canker sores. ...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
