Introduction to Lung Cancer

Lung cancer is a type of cancer that begins in the lungs, which are two spongy organs in the chest that take in oxygen when you inhale and release carbon dioxide when you exhale. Lung cancer is the leading cause of cancer death worldwide, largely due to its detection in advanced stages and its association with smoking. However, it can also occur in people who have never smoked. The disease is primarily categorized into two main types: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), with NSCLC being more common. The development and progression of lung cancer are influenced by a combination of genetic, environmental, and lifestyle factors. Early detection and advancements in treatment have improved survival rates for some lung cancer patients. Examples of scenarios illustrating lung cancer's impact include a long-term smoker developing coughing and breathing issues that are diagnosed as lung cancer, or a non-smoker exposed to high levels of radon gas in their home, later being diagnosed with lung cancer, showcasing the diverse causes and manifestations of the disease.
