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. For example, if cancer has spread to the bones, it might be an abnormal increase in the levels of calcium and alkaline phosphatase.
If you are anemic (due to a low count of red blood cells) If you could have trouble with bleeding (due to a low blood platelet count) If you are at increased risk for infections (due to a low count of white blood cells) A study published in the European Respiratory Journal in July 2020 shows that lung cancer could be detected around three months earlier using a biomarker blood test and CT scanning in high-risk patients.
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. 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.
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. It is in this population of adults that screening can significantly reduce the risk of advanced malignancy and premature death.
According to interim guidance from the U.S. Preventive Services Task Force (USP STF), annual low-dose chest CT scans are recommended if you meet all the following criteria: Used according to these guidelines, CT screening could reduce the lung cancer death rate by 20% in the United States.
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.
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.
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.
Two of the primary causes of lung cancer in non-smokers are radon gas and asbestos. If you believe that radon gas caused your lung cancer, consider calling a lawyer.
Asbestos is yet another natural substance that, if ingested, can lead to lung cancer. 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.

When it comes to cancer, doctors will use a variety of different diagnostic procedures, from the traditional physical exam to laboratory tests and biopsies. The most common symptoms include a persistent cough that lasts for more than a couple of weeks, chest infections that keep recurring, as well as fatigue and loss of appetite.
For this reason, further tests such as the CT scan will give a more detailed image of any potential area that might have cancer. A biopsy will be used to ascertain whether it is malignant or benign and help define the correct course of cancer treatment going forward.
