Lung cancer is the most commonly diagnosed cancer and the leading cause of cancer-related deaths in Canada.
Lung cancer originates in the lungs, typically in the airways (bronchi or bronchioles) or the small air sacs (alveoli). Cancers that begin in other body parts and spread to the lungs are usually named based on their original location. While smoking is the leading risk factor for lung cancer, up to 20% of those diagnosed have never smoked. Therefore, it's essential to discuss any symptoms that are concerning with your provider.
Screening for lung cancer is done using a low-dose computed tomography scan. It is also known as an LDCT scan. During a low-dose CT scan, you lie on a narrow table that moves through a doughnut-shaped machine. This machine uses minimal radiation to take images of your lungs as a camera rotates around you. Computer software combines The resulting slices to create a 3D image of your body. The test is quick and painless, lasting only a few minutes.
