What Is Lung Cancer?
Lung cancer starts when cells in the lungs grow out of control. These cells can form a tumor and spread to other parts of the body. Often, lung cancer does not cause symptoms until it is advanced. Because of this, many people do not know they have it until it is harder to treat. According to the World Health Organization (WHO), lung cancer is one of the most common cancers worldwide.
Why Is Early Detection Important?
Early detection of lung cancer can save lives. When doctors find lung cancer early, treatment is more likely to work. In fact, people diagnosed at an early stage have a better chance of survival. However, many cases are found late, when the cancer has already spread. That is why lung cancer screening is so important. It helps find cancer before symptoms appear.
