It can show the size, shape, position, and depth of any lung tumor. A CT scan test can also be used to look for the spread of lung cancer in the adrenal glands, liver, brain, and other organs.
Routine blood tests are not used to diagnose lung cancer, but they can indicate if cancer has spread to other organs, such as the liver or kidneys. For example, if cancer has spread to the bones, it might be an abnormal increase in the levels of calcium and alkaline phosphatase.
It is often the first imaging test your doctor will order if lung or heart disease is suspected. Chest X-rays are seen in shades of gray and require interpretation by a radiologist trained to spot abnormalities.
Any abnormal growth in the lung will appear on a chest X-ray as a relatively consolidated area of light gray. A chest X-ray alone cannot confirm if a lung nodule, mass, shadow, neoplasm, or lesion is cancer or something more benign, like a cyst or scar.
Pneumonia, which commonly occurs with symptomatic lung cancer, can easily conceal a tumor as pus and mucus start to clog the airways. Even after the TB infection resolves, any remaining spots on the lungs may be presumed to be scarring and left investigated.
Arguably more concerning than misdiagnoses is the number of times a tumor is entirely missed on a chest X-ray. It is not uncommon for someone to be told that a chest X-ray is normal only to find out, months or years later, that cancer is present.
In such cases, this typically only comes to light when advanced symptoms (such as wheezing, unintended weight loss, or the coughing up of blood) develop. While this may suggest negligence is the sole cause of missed diagnoses, chest X-rays fundamentally have limitations, particularly when it comes to detecting certain types and sizes of lung cancer.
Anatomically, cancers in certain parts of the lungs are more difficult to visualize and are more likely to be missed on a chest X-ray. Research published in Diagnostic and Interventional Radiation reported that 45% to 81% of missed lung cancers occurred in the upper lobes where clavicles and other structures obscure the view.
Moreover, doctors often fail to question a patient's past smoking history if they describe themselves as a “non-smoker. In addition, many of the symptoms of lung cancer, such as shortness of breath or fatigue, are non-specific and easily attributed to things like age or obesity.
There are surprisingly few recent studies looking at the actual incidence of missed diagnoses of lung cancer, but the research that has been done is sobering. This not only makes the disease more difficult to manage but significantly reduces a person's survival time.
Computed tomography (CT) scans take multiple X-ray images and combine them in dimensional “slices” so that abnormalities in the lungs can be seen more clearly. Sputum cytology involves coughing up phlegm so that the sample can be checked for cancer cells in the lab.
Lung biopsy, involving the extraction of suspicious tissues by needle or other methods, is ordered if a CT scan suggests cancer. If cancer is diagnosed, other tests will be performed to stage and grade the tumor so that the appropriate treatment can be delivered.
Positron emission tomography (PET) scans are less commonly used for the initial diagnosis of lung cancer and are considered more useful for the staging of the disease. A study published in JAVA involving 150,000 people at high risk of lung cancer reported that four years of annual chest X-rays did nothing to alter the death rate in the group.
Although the consensus among health officials is that the risks of annual CT screening in other groups outweigh the benefits, a 2019 study in the Journal of Thoracic Oncology suggests otherwise. According to the researchers, low-dose CT screening in non-smokers detected a significant number of cancers in the early stages that would have otherwise been missed.
On the downside, it is unclear if annual exposure to low-dose radiation might actually increase the risk of lung cancer over time. As reassuring as a “normal” result may seem, don't allow it to give you a false sense of security if the cause of persistent symptoms remains unknown or if the diagnosis you were given can 't explain them.
Lung, cancer, radon, asbestos, Ilene, awards, case, harmful, exposed, legal you suspect that you have lung cancer, a doctor may use a chest x-ray to diagnose you. If you or a loved one received a diagnosis of lung cancer, and especially if you are a non-smoker, consider that somebody may have exposed you to harmful chemicals at some point in your life.
Two of the primary causes of lung cancer in non-smokers are radon gas and asbestos. According to the American Cancer Society (ACS), radon gas causes approximately 20,000 lung cancer deaths per year.
If you believe that radon gas caused your lung cancer, consider calling a lawyer. If you received a diagnosis of these three affiliated conditions, there is a good chance that you breathed unsafe levels of asbestos fibers at some point in time.

From the WebMD Archives April 8, 2005 -- When the news that Peter Jennings had lung cancer hit earlier this week, many WebMD users asked why doctors don't use chest X-rays to diagnose lung cancer at an early stage, when it's more treatable. WebMD turned to cancer expert Harold Burstein, MD, assistant professor of medicine at Harvard Medical School in Boston, for the answer.
The vast majority of lung cancer cases are caused by smoking, ” Burstein tells WebMD. Chest X-rays are inadequate for diagnosing lung cancers at an early stage, when they are more treatable.
“By the time lung cancers are discovered on chest X-ray, the tumor is often too far advanced to allow the patient to be cured with surgery or radiation therapy. Chest X-rays often miss small, potentially curable lung tumors, as they are too hard to see,” says Burstein.
“If you start getting lots of screening chest X-rays, you end up performing other testing on many patients, which are often unnecessary.” The hope was that these CT scans would be able to find smaller, earlier cancers without leading to further unnecessary tests.
“A variety of recent studies in the U.S. and Japan have suggested that high-resolution CT scans can often detect lung cancers. However, he explains that these were small, early studies that were not able to answer the questions of whether CT scans can actually save lives.
The report by the federal Agency for Healthcare Research and Quality and the U.S. Preventive Health Services Task Force says evidence that chest X-rays, CT scans, and other forms of screening can save lives is poor.

X-rays use high energy rays to take pictures of the inside of your body. Changes can be due to cancer but can also be caused by other lung conditions.
If you have symptoms that could be caused by lung cancer your doctor will arrange for you to have an x-ray. When you arrive in the x-ray department, the radiographer might ask you to change into a hospital gown.
Women may need to remove their bras as metal clips and under wiring can show up on the x-ray. The radiographer lines the machine up to make sure it is in the right place.
Your doctor and radiographer make sure the benefits of having the test outweigh these risks. The amount of radiation you receive from an x-ray is small and doesn't make you feel unwell.
The risk of the radiation causing any problems in the future is very small. The benefits of finding out what is wrong outweigh any risk there may be from radiation.
Unless your doctor thinks it’s urgent the results might take a couple of weeks. Waiting for test results can be a worrying time.
