Final answer:
The most common lung cancer in non-smokers is adenocarcinoma. Even though smoking is the leading cause, non-smokers can develop lung cancer due to various environmental factors. Late diagnosis often leads to lung cancer being the most deadly cancer, and treatments typically include surgery, chemotherapy, and radiation therapy.
Step-by-step explanation:
The most common type of lung cancer in non-smokers is known as adenocarcinoma. While smoking is the leading cause of lung cancer, responsible for about 85% of cases, non-smokers can still develop lung cancer due to other factors such as exposure to radon gas, secondhand smoke, air pollution, and carcinogens like asbestos. Adenocarcinoma is often found in the outer parts of the lung and tends to grow more slowly than other types of lung cancer.
Although lung cancer is not the most common cancer, it is the leading cause of cancer-related deaths, in part because it is frequently diagnosed at a late stage. Treatments for lung cancer may include surgery, chemotherapy, radiation therapy, or a combination of these approaches.
Prevention strategies for non-smokers involve reducing exposure to known risk factors like secondhand smoke and environmental toxins. For smokers or those attempting to quit, cessation is the most effective method for reducing the risk of developing lung cancer and improving overall health.
