Explanation: 

Detailed explanation-1: -The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. These subtypes, which start from different types of lung cells, are grouped together as NSCLC because their treatment and prognoses (outlook) are often similar.

Detailed explanation-2: -There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC).

Detailed explanation-3: -Small cell lung cancer stage 4 SCLC is not typically grouped into numbered stages. Instead, it’s identified as limited stage or extensive stage. With limited-stage SCLC, the cancer is present in one lung and may have spread to lymph nodes near that lung, but it’s contained to one side of the chest.
