keuhkosyöpien

Keuhkosyöpien is the Finnish term for lung cancer. It refers to malignant tumors that originate in the cells of the lungs. Lung cancer is a major cause of cancer-related deaths worldwide. The disease is broadly divided into two main types: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC accounts for the vast majority of lung cancer cases and includes subtypes such as adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. SCLC, while less common, tends to grow and spread more rapidly.

The primary risk factor for developing lung cancer is smoking, which is responsible for the majority of cases. Other risk factors include exposure to secondhand smoke, radon gas, asbestos, and certain industrial pollutants. Symptoms can vary but often include a persistent cough, coughing up blood, shortness of breath, chest pain, wheezing, and unexplained weight loss. Early detection can be challenging as symptoms may not appear until the cancer has progressed.

Diagnosis typically involves imaging tests like chest X-rays and CT scans, followed by a biopsy to examine suspicious tissue. Treatment options depend on the type and stage of the cancer and may include surgery, chemotherapy, radiation therapy, targeted drug therapy, and immunotherapy. The prognosis for lung cancer varies significantly depending on these factors, with earlier stages generally having a better outlook. Prevention strategies focus on smoking cessation and avoiding exposure to known carcinogens.
