Early diagnosis of lung cancer significantly improves the chances of successful treatment and survival. When detected in its early stages, lung cancer is often more localized and can be treated with less invasive options, such as surgery or targeted therapies. Early detection allows doctors to act before the cancer spreads, resulting in better outcomes and a higher quality of life for patients. Regular screening, especially for high-risk individuals, plays a crucial role in catching lung cancer early, making it a critical component of lung health care.
