Lung cancer is the most lethal of the common cancers:

• 80% of those with lung cancer are dead within two years of diagnosis

• Lung cancer accounts for 1 in 3 of all cancer deaths

• Lung cancer kills more people each year than cancers of the breast, colon, prostate and ovary combined

If you are a current or former smoker, you are at significantly greater risk than non-smokers for developing a range of diseases, including lung cancer. According to the US Centers for Disease Control, 10% to 15% of long-term smokers will get lung cancer. The likelihood of developing lung cancer increases steeply after long-term smokers turn 50. On average, smokers are 20 to 30 times more likely to contract lung cancer than life-long non-smokers.
Among smokers, many individuals are at higher than average risk of developing lung cancer due to their genetic make-up.

How the test is done

• Taking the test is as simple as brushing your teeth. After receiving medical authorization for the test from a doctor, a swab is rubbed against the cheeks inside the mouth to collect a small cell sample.
• This sample is sent to our lab which extracts DNA from the cells and analyzes the specific genetic SNP sequences. The genetic code information is combined with the non-genetic information to produce a score which identifies the risk of developing lung cancer.
• Your personalized score and test results will be available approximately 3 weeks after our lab receives your form and test kit.
