10 Symptoms of Non-Small Cell Lung Cancer

Bone pain or headaches. In advanced stages, NSCLC may spread (metastasize) to bones or the brain. Bone metastases can cause persistent pain in the back, hips, or ribs, often mistaken for arthritis. If cancer spreads to the brain, headaches may become frequent, intense, and resistant to regular painkillers. Vision changes, dizziness, or seizures can also occur.

Such symptoms suggest that NSCLC is no longer limited to the lungs and requires urgent treatment.

NSCLC develops more slowly than small cell lung cancer, but it remains the leading cause of cancer death worldwide. Recognizing the symptoms early gives the best chance for successful treatment. If you or someone you know experiences these warning signs, consult a doctor without delay.
