Which type of lung cancer is the most common, accounting for approximately 85% of cases?

Small cell lung cancer
Non-small cell lung cancer
Adenocarcinoma
Squamous cell carcinoma

The correct answer is: Non-small cell lung cancer

Non-small cell lung cancer is the most common type of lung cancer, accounting for about 85% of all lung cancer cases. This category includes several subtypes, such as adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Non-small cell lung cancer tends to grow more slowly than small cell lung cancer, which allows for different treatment strategies and options. The prevalence of non-small cell lung cancer is significant in the overall epidemiology of lung cancer, and its various subtypes have different characteristics, risk factors, and treatment responses. For instance, adenocarcinoma is the most common subtype of non-small cell lung cancer and is often associated with non-smokers or former smokers, while squamous cell carcinoma is typically linked to a history of smoking. Understanding the distinction between these types is vital for healthcare practitioners in making accurate diagnoses and formulating treatment plans tailored to the specific characteristics of the cancer.
