What is Lung Cancer?

Lung Cancer

Quick Answer

A type of cancer that begins in the lungs, lung cancer occurs when cells in the lungs grow uncontrollably. It can affect breathing and overall health, and is often linked to smoking or exposure to harmful substances.

Overview

Lung cancer primarily starts in the cells of the lungs and can spread to other parts of the body. When lung cells become damaged, often due to smoking or exposure to toxic substances, they may start to grow abnormally and form tumors. These tumors can interfere with normal lung function, leading to symptoms like coughing, chest pain, and difficulty breathing. There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is the most common type and tends to grow more slowly, while small cell lung cancer is less common but grows more rapidly. Understanding the type of lung cancer is crucial for determining the best treatment options and outcomes for patients. Lung cancer is significant not only because of its impact on individual health but also due to its prevalence in society. For example, many people diagnosed with lung cancer are former smokers, highlighting the strong link between smoking and this disease. By raising awareness and promoting smoking cessation, communities can work together to reduce the incidence of lung cancer and improve public health.
