Lung Cancer Surpasses Breast Cancer as Leading Cause of Cancer Death in Women
Paris,France - October 3,2025 – Lung cancer has overtaken breast cancer as the primary cause of cancer-related fatalities among women,a shift driven by evolving smoking patterns and improved detection rates for breast cancer,according to recent findings. The change underscores a critical need for increased awareness, earlier diagnosis, and targeted prevention strategies for lung cancer in female populations.
For decades,breast cancer held the unfortunate distinction of being the most deadly cancer for women. However, a combination of factors-including a historical decline in smoking rates among men coupled with a slower decrease among women, as well as advancements in breast cancer screening and treatment-has altered this landscape. This transition means more women are now succumbing to lung cancer than to breast cancer annually, presenting a notable public health challenge.
Pr Marie-Pierre Revel, a leading expert in the field, emphasizes the urgency of this evolving trend. “Lung cancer today kills more women than breast cancer,” she stated, highlighting the need for greater vigilance and proactive measures. While breast cancer remains a significant threat, the rising incidence and mortality rates of lung cancer in women demand immediate attention.
The shift is notably pronounced in certain demographics, with women who have never smoked still accounting for a substantial percentage of lung cancer diagnoses. This suggests that factors beyond smoking, such as genetic predisposition and environmental exposures, play a crucial role in the development of the disease. Increased research into these contributing factors is vital for developing more effective prevention and treatment strategies.
