Which type of lung cancer generally has a worse prognosis due to its rapid growth and increased metastases?

Small cell lung cancer (SCLC) is known for its aggressive nature and rapid growth, which contribute to its poorer prognosis compared to other types of lung cancer. This type of cancer typically metastasizes earlier and more extensively, making it more challenging to treat effectively. The cells in SCLC are often small and round, and they can proliferate quickly, leading to a heightened risk of spread to distant parts of the body, such as the liver, bones, or brain.

In contrast, non-small cell lung cancer (NSCLC) tends to grow more slowly and can often be treated with surgery if detected early. Mesothelioma, while serious, is a type of cancer linked primarily to asbestos exposure, and its prognosis is influenced by different factors. Adenocarcinoma is a subtype of NSCLC and also has a comparatively better prognosis than SCLC. Overall, the distinctive characteristics of SCLC highlight its aggressive behavior and poor prognosis, setting it apart from the other types mentioned.
