Can lung cancer ever appear on an xray, be diagnosed as pneumonia and then not appear on two subsequent xrays or was it really pneumonia.

Can lung cancer ever appear on an xray, be diagnosed as pneumonia and then not appear on two subsequent xrays or was it really pneumonia.

Why do you ask?: I am glad it is gone. I would trust the imaging specialist especially if there are two films without cancer after the pneumonia is gone.

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

Does a sternum X-ray rule out lung cancer?

Does a sternum X-ray rule out lung cancer?

No: This x-ray is too limited. We have proven a ct of the chest is very helpful in screening for hi risk people though you don't fit age (55 to 74 who smoked > pack of cig/day for >30 ys and who are still smoking or who <15 yrs ago). Smoking volume history, infections and other factors should be considered before scans. With suspicion your primary md may still start with a chest xray before ct.

If one had lung cancer symptoms. Would it show on an X-ray and bloods.?

If one had lung cancer symptoms. Would it show on an X-ray and bloods.?

It might--or not: Advanced lung cancer would show on x-ray. Earlier cancers are better seen with ct scans. If you have been a heavy smoker for 15 or more years, your risk is certainly much higher of a cancer than a non-smoker. Non-smoking related cancers occur, but usually in much older individuals.

If I have chest pain and my X-ray was clear do I need to worry about lung cancer why would a tumor not show?

If I have chest pain and my X-ray was clear do I need to worry about lung cancer why would a tumor not show?

Many causes of Pain: Pain in the chest can be caused by many different reasons. Lung cancer can be one of these but it will often produce other symptoms such as cough and shortness of breath. If a chest X-ray is normal then you are not likely to have any tumor in your lungs. Other reasons to exclude is Angina (although it is a disease of the older people) or muscular pain (this is the most likely reason). Such pains go

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

Yes and no: When Cancer starts to spread, it begins as clusters of cells that form tiny colonies in other body parts. These will grow in size over a few months to become visible on X-rays and various diagnostic imaging tests such as CT scan and or PET scan. Blood tests do not show cancer cells, so we rely on the above imaging tests and repeat them periodically (every 2-3 months) to monitor for the tumor growt

For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

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.

Can you see lung cancer in a chest x-ray?

Can you see lung cancer in a chest x-ray?

Maybe: It depends on the size and location of the lung cancer. Small cancers (less than 1 cm) may be difficult to identify with chest radiographs. Ct scan of the chest is much more sensitive in evaluating for lung cancer and associated disease.

Would a clear chest X-ray mean there is no lung cancer?

Would a clear chest X-ray mean there is no lung cancer?

Not necessarily: Chest xrays are not regarded as good lung cancer screening tools. Ct-scan, while imperfect, is currently the best demonstrated screening tool for lung cancer. A proper protocol chest ct will use about the same radiation as a mammogram. http://goo. Gl/b69an.

Need doctor's help! Will lung cancer be missed on a pet?

Need doctor's help! Will lung cancer be missed on a pet?

Maybe: Most lung cancers will be seen on a pet/ct scan, unless they are very small. But if it's the size of a blueberry or larger, it will be seen. Pet scans show bright spots where cells are using a lot of sugar (see picture). This can be from a cancer, an infection, or inflammation. So a negative pet scan means you probably don't have lung cancer. If you do, it's tiny! I hope you feel better!

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
