There are three types of NCSLC, all of which are outlined below.
Adenocarcinoma is the most common subtype of NSCLC and accounts for 35% to 40% of all NSCLC. These types of tumors often develop at the edges of the lungs and in cells lining the airways. They grow at various rates and can be asymptomatic in the early stages. Adenocarcinoma is often linked to smoking but is also the most common lung cancer diagnosed in nonsmokers. Adenocarcinoma is more prevalent in women than in men.
Squamous Cell Carcinoma
Squamous cell carcinoma accounts for about 30% of all NSCLC and is often linked to smoking. It is generally detected in the middle of the lungs and also grows at various rates.
Large Cell Carcinoma
Large cell carcinoma accounts for 10% to 20% of all NSCLC. It can occur in any part of the lungs and spreads rapidly. Like adenocarcinoma and squamous cell carcinoma, these tumors are often associated with smoking.
