Lung cancer is a type of cancer that begins in the lungs, which are vital organs located in the chest responsible for breathing and oxygen exchange. There are two primary types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC accounts for about 85% of lung cancer cases and typically grows slower than SCLC, which is more aggressive and spreads quickly. Common risk factors for lung cancer include smoking, exposure to secondhand smoke, radon gas, and certain occupational hazards, making it essential to take preventive measures if you are at risk.
Symptoms of lung cancer can be subtle in the early stages, often including a persistent cough, chest pain, breathlessness, weight loss, and coughing up blood. Given that many individuals may not experience noticeable symptoms until the disease has progressed, regular check-ups and screenings are crucial, especially for those at higher risk. Treatment options for lung cancer may involve surgery, chemotherapy, radiation therapy, targeted therapy, or a combination of these approaches, depending on the cancer's type and stage. As research advances, new treatments are being developed, offering hope for improved survival rates and quality of life for those diagnosed.
