lung cancer pathophysiology

Lung cancer includes two main types: non-small cell lung cancer and small cell lung cancer. There are 2 components of early detection: Early diagnosis. While the exact causes of non-small cell lung cancer are uncertain, several risk factors have been identified. Non-small cell cancer accounts for 85% to 90% of all lung cancers (1). It usually spreads more quickly and is often at an advanced stage when it’s diagnosed. For lung cancer, the worldwide leading cause of cancer death, the evidence from single studies and from systematic reviews and meta-analyses have been mixed, but consistent, in indicating an inverse relationship between body mass index (BMI) and lung cancer risk.

For lung cancer patients, this means that therapy can be an option for those with mesothelioma, which affects the lining around the lungs. Small-cell lung cancer, sometimes called SCLC, causes about 10% to 15% of all lung cancers. The genes influenced in the pathogenesis of the cancer generate proteins involved in cell development and differentiation, apoptosis, tumor progression, cell cycle processes, angiogenesis, and immune regulation. (Data from Siegel R, Ward E, Brawley O, et al. Tests may include: Imaging tests. Cancer from other organs also may spread to the lungs.
