Title
Association between low-fat dairy consumption and risk of lung cancer in the PLCO Cancer Screening Trial
Summary
According to the Global Cancer Statistics, lung cancer is the second most common malignancy after female breast cancer, with approximately 2.2 million new diagnosed cases in 2020, accounting for 11.4% of all cancers(1). The association of dairy consumption with a variety of cancers has been investigated. However, there are only a few studies on lung cancer and the results are controversial(2-4). Previous evidence suggested that the relationship between dairy products and cancers may vary depending on the fat content and types of dairy products(5). Therefore, we speculate that the inconsistent findings for lung cancer may result from differences in dairy products. In recent years, low-fat dairy products have replaced whole-fat dairy products in the main dietary guidelines due to their more beneficial effects on human health(6). However, the relationship between low-fat dairy consumption and lung cancer risk is unclear. we performed this study to investigate this relationship.
