Lung cancer is a form of cancer which is one of the leading causes of death worldwide. The scariest thing about this type of cancer is that there are no early warning signs. By the time it has been diagnosed, the cancer has usually already entered its aggressive stage, at which point mortality rate is very high. However, if the cancer is found during the early stages, the chance of survival can be as high as 90%, if treated correctly.
Smoking is the main cause of lung cancer. Smokers are therefore targeted for screening, as they are most at risk. However, here are many groups who are also at risk of lung cancer, such as passive smokers or people who live or work in areas with high levels of asbestos, radioactive substances, industrial or vehicle pollutants, as well as people with a family history of lung or any other cancer.
Screening for lung cancer in its early stages can be carried out through low-dose computed tomography. This method is currently preferred due to its speed and accuracy in identifying cancerous lumps, however small they may be, and even when they may be obstructed by other organs. This means that a reduction in mortality rates is possible when compared to those who avoid undergoing regular lung X-ray cancer screening. When the cancer is identified, doctors can immediately proceed with treatment to ensure that the cancer is eradicated at this early stage.
For anyone falling into a categories mentioned above, a doctor’s appointment should be made to receive advice on the appropriate next step, ensuring that lung cancer is not allowed to take your life or the life of someone you love.
