Lung cancer is a leading cause of cancer deaths worldwide, accounting for approximately 1.8 million fatalities annually. It is the second most common type of cancer diagnosed in both men and women, with the majority of cases being diagnosed at an advanced stage.
The primary causes of lung cancer are smoking, exposure to radon gas, and asbestos. However, it can also be caused by other factors such as air pollution, occupational hazards, and genetic predisposition.
The treatment options for lung cancer depend on the stage of the disease, overall health status, and patient preferences. Surgical resection is often the primary treatment approach for early-stage lung cancers.
Chemotherapy is commonly used in combination with surgery or radiation therapy to treat advanced-stage lung cancers. Targeted therapies are also being explored as a potential treatment option.
Early detection is crucial in the fight against lung cancer. Low-dose computed tomography (LDCT) scans are recommended for high-risk individuals, such as heavy smokers.
Prevention is also key. Quitting smoking, avoiding secondhand smoke, and maintaining a healthy lifestyle can significantly reduce the risk of developing lung cancer.
