Lung cancer diagnosis involves a combination of imaging tests, biopsies, and other procedures to confirm the presence of cancer.

Q1: What are the common symptoms of lung cancer?

• Persistent cough that worsens.
• Chest pain that is often worsened by deep breathing.
• Shortness of breath.
• Unexplained weight loss.
• Coughing up blood.

Q2: What imaging tests are used for lung cancer diagnosis?

• X-rays: Initial imaging to look for abnormalities.
• CT scans: Provide detailed cross-sectional images of the lungs.
• PET scans: Help to identify cancerous activity in the body.

Q3: How is a biopsy performed?

• Bronchoscopy: A thin tube is inserted through the mouth or nose into the lungs to collect tissue samples.
• Needle biopsy: A needle is used to extract tissue from the lung through the chest wall.
• Surgical biopsy: More invasive; involves the removal of part of the lung for analysis.

Q4: What role does pathology play in lung cancer diagnosis?

Pathologists analyze tissue samples to confirm the presence of cancer cells and determine the type of lung cancer, which is critical for treatment planning.

Q5: How important is staging in lung cancer diagnosis?

Staging helps determine how far the cancer has spread, influencing treatment options and prognosis. The most common staging system used is the TNM system, which considers Tumor size, Node involvement, and Metastasis.

Q6: Can lung cancer be diagnosed at an early stage?

Yes, lung cancer can be diagnosed at an early stage through routine screenings such as low-dose CT scans, particularly for high-risk individuals like heavy smokers.

Q7: What new technologies are being developed for lung cancer diagnosis?

• Liquid biopsies: Analyzing blood samples for cancer biomarkers.
• Artificial intelligence in imaging: To enhance detection rates in scans.
