What Is Lung Cancer?

Lung cancer is the leading cause of cancer death worldwide. It begins when cells in the lungs grow abnormally and form tumors. While smoking is the primary risk factor, 10-20% of lung cancer patients have never smoked.

Recent advances in targeted therapies and immunotherapy have dramatically improved outcomes, especially for patients with specific genetic mutations. Early detection through low-dose CT screening is also saving lives.

Types of Lung Cancer

Non-Small Cell Lung Cancer (NSCLC)
85% of cases
  • •Adenocarcinoma (40%)
  • •Squamous cell carcinoma (25-30%)
  • •Large cell carcinoma (10-15%)
Small Cell Lung Cancer (SCLC)
15% of cases
  • •More aggressive
  • •Often spreads early
  • •Strong link to smoking

Common Symptoms

Persistent cough that doesn't go away
Coughing up blood (hemoptysis)
Shortness of breath
Chest pain that worsens with breathing/coughing
Hoarseness or voice changes
Unexplained weight loss
Bone pain (if spread to bones)
Frequent lung infections (pneumonia, bronchitis)

Early lung cancer often has no symptoms. If you're high-risk (smoker or former smoker aged 50-80), talk to your doctor about low-dose CT screening.

Risk Factors

Smoking (85-90% of lung cancers)

Secondhand smoke exposure

Radon gas exposure

Asbestos and other carcinogens

Family history of lung cancer

Previous radiation to chest

Air pollution

Chronic lung diseases (COPD)

Treatment Options

Surgery
  • •Lobectomy (remove lung lobe)
  • •Pneumonectomy (remove entire lung)
  • •Wedge resection (small tumors)
Radiation Therapy
  • •Stereotactic body radiotherapy (SBRT)
  • •External beam radiation
  • •Brachytherapy
Chemotherapy
  • •Platinum-based combinations
  • •Neoadjuvant (before surgery)
  • •Adjuvant (after surgery)
Targeted Therapy
  • •EGFR inhibitors (Tarceva, Tagrisso)
  • •ALK inhibitors (Alecensa, Lorbrena)
  • •ROS1, BRAF, MET inhibitors
Immunotherapy
  • •Keytruda, Opdivo, Tecentriq
  • •PD-1/PD-L1 checkpoint inhibitors
  • •First-line for many advanced cases

Critical Biomarkers for Treatment

EGFR Mutations

Most common targetable mutation (10-15% of NSCLC), highly responsive to TKIs

ALK Rearrangements

Found in 3-5% of NSCLC, excellent targeted therapy options

PD-L1 Expression

Predicts immunotherapy response (>50% expression = single-agent immunotherapy)

KRAS G12C

Previously 'undruggable,' now has targeted therapy (Lumakras)

ROS1, BRAF, MET

Rare but actionable mutations with targeted therapies

Latest Research & Breakthroughs

  • Immunotherapy revolutionizing first-line treatment for advanced NSCLC
  • Targeted therapies for KRAS G12C mutations (Lumakras, Krazati)
  • Low-dose CT screening reducing lung cancer deaths by 20%
  • Liquid biopsy for early detection and treatment monitoring
  • Combination immunotherapy + chemotherapy improving survival
  • Next-generation EGFR and ALK inhibitors overcoming resistance
