This JAMA Patient Page describes Lynch syndrome, its risk factors and diagnosis, and its association with colorectal cancer and other specific cancers.
Lung cancer has the highest mortality rate of any cancer in Canada, causing 25.5% of all cancer deaths, with a 5-year survival rate of only 19%. More than half of lung cancers are metastatic at diagnosis, with common sites of metastases in the brain, bone, liver, and adrenal glands. Lung cancer is a heterogeneous group of cancers broadly separated into small cell lung cancer (SCLC)—approximately 15% of all lung cancer cases—and non–small cell lung cancer (NSCLC), which is further divided into predominantly adenocarcinoma and squamous cell carcinoma subtypes. More than 80% of lung cancer cases are related to smoking, meaning smoking cessation remains the cornerstone of lung cancer prevention. Low-dose computed tomography is a valuable screening tool for lung cancer that can identify lung cancers at an earlier stage and reduce lung cancer–specific mortality and all-cause mortality. Although lung cancer screening is recommended by the Canadian Task Force on Preventive Health Care, it is currently available in only a few Canadian provinces.
