On World Lung Cancer Day, Data Show Surge in Female and Younger Cases, Prompting Calls for Screening and Research

Late diagnosis remains the main barrier to improving survival.

Overview

  • Spain’s GECP reports the fastest growth in female lung cancer in Europe, with women now near 28% of cases and female mortality up 7% in 2024 as 1 in 20 diagnoses occurs before age 50.
  • Andalusian oncologists warn that up to one in five cases arise in never‑smokers, urging prevention that targets air pollution, radon and occupational exposures alongside molecular testing access.
  • More than half of patients are diagnosed at stage III or IV and only about 10% at early stages, with five‑year survival around 30% despite gains from targeted therapies and immunotherapy.
  • Low‑dose CT screening pilots in Spain (Proyecto Cassandra) now operate in 15 hospitals across six regions and plan further expansion, with evidence suggesting a 20–25% reduction in mortality in high‑risk groups.
  • Tobacco remains the leading driver at roughly 85% of cases as experts caution that vaping is not harmless and is growing among youth, reinforcing calls for stronger tobacco control and public health measures.
