Lung Cancer
About Lung Cancer
Lung cancer is a type of cancer that begins in the lungs. It occurs when cells in the lung start to grow out of control, potentially forming tumors and impairing lung function.
Common Symptoms
- persistent cough
- coughing up blood or rust-colored sputum
- shortness of breath
- chest pain
- hoarseness
- weight loss without trying
- bone pain
- headache
Diagnosis
Diagnosis often begins with a review of symptoms and a physical exam, followed by imaging tests such as X-rays or CT scans. A definitive diagnosis typically involves a biopsy, where a small tissue sample from the lung is examined under a microscope.
Causes
The primary cause of lung cancer is smoking tobacco, including exposure to secondhand smoke. Other factors may include exposure to radon gas, asbestos, and other carcinogens, as well as a family history of lung cancer.
Treatment Overview
Treatment approaches for lung cancer are varied and depend on the type and stage of cancer, as well as the individual's overall health. Conventional treatments commonly include surgery, chemotherapy, radiation therapy, targeted drug therapy, and immunotherapy. Some individuals may explore complementary approaches, such as acupuncture or nutritional strategies, often alongside conventional care.
Prognosis & Outlook
The prognosis for lung cancer can vary significantly depending on factors such as the stage of the cancer at diagnosis, the specific type of lung cancer, and an individual's response to treatment. Early detection may be associated with a more favorable outlook.
Types & Variants
Non-Small Cell Lung Cancer (NSCLC)
The most common type, accounting for about 80% to 85% of cases. It includes several subtypes, such as adenocarcinoma and squamous cell carcinoma, and generally grows and spreads more slowly than SCLC.
Small Cell Lung Cancer (SCLC)
Occurs almost exclusively in heavy smokers and is less common, making up about 10% to 15% of cases. This type is known for growing and spreading quickly.
