Yang Yang, MD, Medical Doctor in the Department of Radiation Therapy, Zhejiang Cancer Hospital (China), et al., in a Feb. 15, 2016 study published in Scientific Reports titled "Dairy Product, Calcium Intake and Lung Cancer Risk: A Systematic Review with Meta-Analysis," wrote:

“A total of 26 studies focused on the association between dairy consumption and lung cancer risk were identified, and an additional 6 studies that reported the calcium intake and lung cancer risk were found, including 12 cohort studies and 20 case-control studies. Among them, 12 studies were conducted in Europe, 12 in the Americas, 7 in Asia, and 1 in the South Pacific…

In this meta-analysis [of 26 studies on dairy consumption and lung cancer risk], we found that the intake of dairy products, including total dairy, milk, cheese, yogurt, or low-fat milk, as well as calcium were not significantly associated with lung cancer risk. The association remained unchanged when stratified by study design, gender, geographic area, quality and smoking status. Our results are consistent with the findings from the largest cohort study (NIH-AARP Diet and Health Study), and this null association was also found in many other types of cancer, such as gastric, bladder and pancreatic cancers.”
