Keuhkosyöpätapausten

Keuhkosyöpätapausten refers to lung cancer cases. Lung cancer is a disease characterized by uncontrolled cell growth in the lungs. It is a major global health concern and a leading cause of cancer-related deaths. The primary cause of lung cancer is long-term exposure to tobacco smoke, accounting for the vast majority of cases. Other risk factors include exposure to secondhand smoke, radon gas, asbestos, certain industrial chemicals, and air pollution. Genetic predisposition can also play a role.

There are two main types of lung cancer: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC is more common and includes subtypes like adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. SCLC is less common but tends to grow and spread more quickly. Symptoms of lung cancer can vary but often include a persistent cough, coughing up blood, shortness of breath, chest pain, wheezing, and unexplained weight loss. Early stages may be asymptomatic, making diagnosis challenging.

Diagnosis typically involves imaging tests such as chest X-rays and CT scans, followed by a biopsy to confirm the presence of cancer cells and determine the type. Treatment options depend on the type and stage of the cancer, as well as the patient's overall health. These can include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Prevention strategies focus on avoiding tobacco use and minimizing exposure to other known risk factors. Public health initiatives aim to reduce smoking rates and raise awareness about the risks associated with lung cancer.
