Symptoms & Early Warning Signs
Common indicators and clinical warning signs
Note: Many lung cancers have no symptoms in early stages, which is why screening is important for high-risk individuals (smokers, former smokers).
Diagnosis Pathway
Step-by-step clinical evaluation and staging workflow
Medical history and physical examination
Chest X-ray to detect abnormalities
CT scan of the chest for detailed imaging
Sputum cytology (if coughing up sputum)
Biopsy (needle, bronchoscopy, or surgical)
PET scan to check for spread
Pathology report and staging (NSCLC vs SCLC)
Staging Explained
How tumor size, lymph node involvement, and metastasis are graded
Carcinoma in situ (abnormal cells only in lining)
Small tumor, no lymph node involvement
Larger tumor or nearby lymph node involvement
Locally advanced, spread to lymph nodes or nearby structures
Metastatic (spread to distant organs like brain, bones, liver)
Treatment Options
Standard of care modalities according to NCCN clinical guidelines
Surgery
Lobectomy (removal of one lobe), pneumonectomy (entire lung), or wedge resection. Used for early-stage non-small cell lung cancer (NSCLC).
Chemotherapy
Systemic treatment to kill cancer cells. Used for all stages, often combined with other treatments. Common for small cell lung cancer (SCLC).
Radiation Therapy
Targeted radiation to destroy cancer cells. Used alone or with chemotherapy. May be used before or after surgery.
Targeted Therapy
Drugs targeting specific genetic mutations (EGFR, ALK, ROS1, BRAF). Requires genetic testing. Examples: osimertinib, crizotinib.
Immunotherapy
Drugs that help immune system fight cancer (PD-1/PD-L1 inhibitors). Examples: pembrolizumab, nivolumab. Used for advanced NSCLC.
Radiofrequency Ablation
For small tumors, uses heat to destroy cancer cells. Minimally invasive option for some early-stage patients.
