Can chest xray detect early lung cancer?

Can chest xray detect early lung cancer?

Sometimes: Sometimes 8-10 mm lung lesions can be detected. Detection depends on location of lesion whether it is central or peripheral. Central lesions near mediastinum are many times difficult to recognize on plain radiograph. Cross sectional imaging such as CT is much more sensitive for small hidden lesions than radiograph. ...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

Can chest x rays miss a lung infection?

Can chest x rays miss a lung infection?

Yes: Chest xray looks at the lung tissue superimposed on a the chest wall tissue including the ribs and all the muscles and thus can miss subtle findings. In addition, lung infection can be subtle, with presentation as a small focus of infection or a rather very faint infection area that can be very difficult to detect with xray alone. A ct study may be useful if necessary. ...Read more

Can one chest CT scan damage lung and cause lung cancer ?

Can one chest CT scan damage lung and cause lung cancer ?

Not likely: The natural exposure one might get just from where you live may exceed 3msv per year. Living in denver, you might be exposed to 6msv per year. Risk of developing cancer from a properly conducted ct scan is low. I believe the estimated average radiation exposure for a single chest ct is about 5-7msv. A low dose chest ct is about 2msv. ...Read more

Can a chest X-ray or echo detect lung cancer?

Can a chest X-ray or echo detect lung cancer?

Not easily: Cxr has been compared head to head with chest ct scan for screening in high risk patients for lung cancer. That study, national lung screening trial, found that in high risk patients, screening chest ct scan was more effective, and was found to save lives. Larger cancers might be seen on a cxr, but smaller cancers may be missed. ...Read more

Dx of lung nodules. Ct scans of chest two years. Had chestxr CT scan of chest 2012 2013 CT scan of chest pulm wants another im afraid it causes cancer?

Radiation from CT: This issue should be discussed with your pulmonary doctor and radiologist. There is some risk associated with the radiation from multiple ct scans. However, that risk is likely small compared to the risk of a nodule identified in the lung, and may not outway the risks of ct, in the long run. There should be a plan with a reasoned approach that minimizes the risk of ct that you can agree with. ...Read more

I have stage 2 emphysema and 4 lung nodules on a ct scan (3mm and smaller) shadow xray and CT scan. Shortness breath, chest pain, night sweats?

Mgt/workup: Your findings are of concern, and an exam documenting any lymphadenopathy is important. I would suggest seeing your PCP. Your symptoms may also be due to TB, cardiac disease, pulmonary embolism. A virtual online appt is available for follow up and to review your HRCT. healthtap.com/DosanjhMD Code: NCYHPZ ...Read more

Hist chest pain and hemopsys. normal CXR CT shows calcified hilar node. Ca of 10.8 now 9.7 Dr Doesnt think Squamus lung cancer no smoker Bronchoscopy?

Hist chest pain and hemopsys. normal CXR CT shows calcified hilar node. Ca of 10.8 now 9.7 Dr Doesnt think Squamus lung cancer no smoker Bronchoscopy?

See below: Is this your PCP or pulmonologist saying this? There are many causes of enlarged hilar lymph nodes. Also, if it is calcified, that is usually just a sign of old granulomatous disease, like histoplasmosis. And at 31, that would be unusual to have lung cancer - not unheard of - but unusual. ...Read more

Would a chest xray show lymphoma?

Would a chest xray show lymphoma?

It depends...: It depends on the area covered by the x-ray and on how enlarged the lymph nodes are. A chest x-ray would probably show significant lymph node enlargement that may be suspicious for lymphoma in the mediastinal area (inside the chest cavity) and possibly in the supraclavicular (above the collarbone), lower cervical (neck), and axillary (armpit) regions. Inguinal (groin) lymph nodes would not show. ...Read more

Bilateral hilar enlargement with cardiomegaly.In chest x ray. What's next?

Depends: Depends on your symptoms. If hilar adenopathy is suspected, a CT scan with contrast is indicated. If CHF is suspected, a BNP (blood sample) would be helpful. Regardless, an echocardiogram is indicated to evaluate cardiomegaly (an enlarged heart shadow). Other tests may also be necessary depending on the situation. ...Read more

Clear CT scan of chest.  Worried about lung cancer.  Two x rays and one CT clear.  But the CT was without contrast & shoulder pain persists. Contrast?

NO!: Lung cancer has been eliminated as a realistic diagnosis. Move on, be glad. There are rather more mundane causes for shoulder pain. See an orthopedic surgeon and find out what's going on with that shoulder. ...Read more

Are small nodes seen on lungs thru chest CT scan suggesting lung cancer or something else?

Not necessary: Are you referring as small lymph nodes or small nodules on the lung? There are other conditions beside cancer that can be presented with small nodes - including infections, inflammation, autoimmune process, etc. So, a good history, examination, blood work and serial imaging would be necessary to be done. Discuss with your md in detail. ...Read more

Severe chest pain, calcium screening showed chronic pulmonary hypertension& lung nodules. Had CT of chest 3mm & 8mm noncalcified granulomas.helpplease?

Lung nodules: many causes of lung granulomas. Histoplasmosis a fungus in the dirt is probably most common cause. Being around construction sites or bird handling are frequent causes especially around Ohio river. Connective tissue causes like sarcoidosis and wegeners can also cause. Working in dusty areas or around talc is known cause. With pulmonary hypertension you need to see a pulmonologist for definitive dx ...Read more

Can a chest CT scan rule out lung cancer?  I have pain in shoulder/clavicle. X ray and CT clear.  Pain persists along with sore sternum/throat.

Yes: A chest ct is a very good test for finding lung cancer because it looks inside the lungs. The shoulder/clavicle pain could be coming from the spine in your neck. If you still have pain, see your doctor again. ...Read more

Can multiple lung lesion 2.5cm in size be detected on routine chest x rays?

Yes: The resolution of the cxr is such that it should be able to show lesions this big. The advent of the digital xr even makes it easier to see them. It still does not give us the diagnosis, it only makes us see them so we can work them up. ...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

Xray Of Chest (Definition)

A chest x-ray is the basic radiographic study for evaluation of the heart and lungs. It usually consists of 2 views: postero-anterior and lateral. The image is now usually acquired digitally with the sensor placed against the front of the chest for the pa view and on the left side of the chest for the lateral view. Pneumonia, heart enlargement, CHF and many other ...Read more
