November is Lung Cancer Awareness month. The reason for this awareness is to draw attention to the fact that, caught early, most cases of lung cancer can be treated. Too often, however, lung cancer produces no symptoms early on. Its stealthy nature allows it to grow and spread without warning, making it the #1 cause of cancer death in the US. Once symptoms like coughing, wheezing and shortness of breath occur, they signal the spread of cancer outside the lungs, where it is usually impossible to treat. 80-90% of lung cancer cases are caused by heavy smoking, so if you are or were a heavy smoker, the key is discovering lung cancer while you still feel healthy, and before you experience signs.
Early discovery is possible with low dose computed tomography, or LDCT, a highly detailed annual screening exam that sees fine details within the lungs in just minutes, without contrast dye or invasive procedures. This painless low-dose CT scan is capable of seeing the lungs with nearly 3D clarity, to pinpoint cancer while it is still small and localized.
According to the American College of Radiology Imaging Network’s National Lung Screening Trial, people who received LDCT screening exams had a 15-20% lower risk of lung cancer death than those receiving standard chest x-rays. If you are or were a heavy smoker, that can make all the difference to your health and safety. That’s why the American Lung Association recommends LDCT screening instead of chest x-ray for current and former heavy smokers.
What Defines a Heavy Smoker?
You are considered to be at higher risk of lung cancer if you currently smoke or quit within the last 15 years and meet either of the following criteria:
You are 55-77 and have reached 30 pack years, which is determined by the number of years spent smoking multiplied by the number of packs smoked per day. 1 pack a day x 30 years, or 2 packs a day x 15 years = 30 pack years.
You are 50 or older and have reached 20 pack years and have a personal or family history of lung disease. 1 pack a day x 20 years + asthma, COPD, chronic bronchitis, or other lung disease, OR you have a first-degree relative (parent, sibling, child) with lung disease.
With a qualified clinician’s referral, patients 55-77 who have reached 30 pack years are eligible to have their LDCT scans covered by Medicare. If you have reached 20 pack years and have a personal or family history of respiratory disease, talk to your clinician about whether LDCT screening may be covered in your case.
