Lung cancer is a significant public health issue worldwide. It is one of the most common types of cancer and a leading cause of cancer-related deaths. The prevalence of lung cancer varies across different populations and is influenced by various factors such as age, gender, smoking habits, and environmental exposures.
In terms of global prevalence, lung cancer accounts for approximately 11.6% of all cancer cases, making it the most commonly diagnosed cancer. It is responsible for around 18.4% of cancer-related deaths globally, making it the leading cause of cancer mortality.
The prevalence of lung cancer is strongly associated with smoking. Smoking tobacco is the primary risk factor for developing lung cancer, with approximately 85% of cases attributed to smoking. However, it is important to note that non-smokers can also develop lung cancer due to other factors such as exposure to secondhand smoke, radon gas, asbestos, air pollution, and genetic predisposition.
Early detection and prevention strategies are crucial in reducing the prevalence of lung cancer. Implementing smoking cessation programs, raising awareness about the risks of smoking, promoting healthy lifestyles, and reducing exposure to environmental carcinogens are essential in combating this disease.
