Lung Cancer
Lung cancer begins in the cells of the lungs and is among the most common and serious types of cancer. It is broadly categorized into non-small cell and small cell types.
Understanding Lung Cancer
Lung cancer develops when abnormal cells grow uncontrollably in lung tissue. The two main types are non-small cell lung cancer (NSCLC), which accounts for about 85% of cases, and small cell lung cancer (SCLC), which tends to grow and spread more quickly.
Treatment approaches have advanced significantly, with targeted therapies and immunotherapy now playing important roles alongside traditional surgery, chemotherapy, and radiation.
Common Symptoms
- Persistent cough that worsens over time
- Coughing up blood or rust-colored sputum
- Shortness of breath or wheezing
- Chest pain that may worsen with deep breathing
- Unexplained weight loss and fatigue
- Recurrent respiratory infections
How It Is Diagnosed
Diagnosis involves imaging (chest X-ray, CT scan), sputum cytology, and biopsy procedures such as bronchoscopy, needle biopsy, or surgical biopsy. Molecular testing of tumor tissue helps guide targeted therapy decisions.
Frequently Asked Questions
Common questions about Lung Cancer
Can non-smokers get lung cancer?
Yes. While smoking is the leading risk factor, approximately 10-20% of lung cancers occur in people who have never smoked. Other risk factors include radon exposure, secondhand smoke, and genetic factors.
What is biomarker testing?
Biomarker or molecular testing examines tumor tissue for specific genetic mutations or protein expressions that can guide treatment decisions, particularly for targeted therapies and immunotherapy.
