Lung Cancer Surges in Women Under 50

Lung cancer has surpassed men in incidence among women under 65, with a notable rise in women under 50, a trend identified as of 2021. This increase is linked to modern lifestyle factors and environmental exposures, including pervasive air pollution in Indian cities and indoor smoke from biomass fuels. Poor ventilation and passive smoking further elevate risk.

Biological factors also play a role, with women, particularly Asian women, being more susceptible to adenocarcinoma, a lung cancer subtype often found in non-smokers. Genetic mutations and hormonal differences may increase susceptibility. This leads to younger, non-smoking women being diagnosed with advanced lung cancer, a situation no longer rare.

Delay in diagnosis is a significant danger, as symptoms are often attributed to pollution, allergies, or infections. However, persistent respiratory issues warrant lung imaging. While concerning, lung cancer in women can be biologically more treatable, with early-stage disease curable through surgery or radiotherapy. Modern treatments like targeted therapies and immunotherapy are improving outcomes for advanced cases.
