keuhkosyövistä

Keuhkosyöpä, or lung cancer, refers to uncontrolled cell growth in the lungs. It is a significant global health concern, often associated with smoking, which is the primary risk factor. Other contributing factors include exposure to secondhand smoke, radon gas, asbestos, and certain occupational pollutants.

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 rapidly.

Symptoms of keuhkosyöpä can vary but often include a persistent cough, coughing up blood, shortness of breath, chest pain, hoarseness, and unexplained weight loss. These symptoms may not appear until the cancer has progressed significantly.

Diagnosis typically involves imaging tests like chest X-rays and CT scans, followed by a biopsy to confirm the presence of cancerous cells and determine the type of cancer. Staging the cancer is crucial for determining the best course of treatment.

Treatment options depend on the type and stage of the cancer, as well as the patient's overall health. They can include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy. Early detection and prompt treatment are vital for improving outcomes. Prevention strategies, primarily focused on smoking cessation and avoiding exposure to known carcinogens, are paramount in reducing the incidence of lung cancer.
