Over a median follow-up period of 12.0 years, the cohort study recorded 1,182 lung cancer cases in women.
According to the researchers, several reproductive factors showed a significant association with a higher risk of incident lung cancer among women. These factors included early menarche (age ≤ 11 years), early menopause (age ≤ 46 years or age of 47-49 years), a shorter reproductive span (age less than or equal to 32 years or age of 33-35 years), and early age at first birth (≤ 20 years or age of 21-25 years).
Stratified analysis revealed that some reproductive factors, especially early menopause, shortened reproductive span, and early age at first birth, displayed a substantially stronger association with elevated lung cancer risk, particularly non-small cell lung cancer (NSCLC), in populations with high genetic susceptibility and detrimental behaviors.
“These findings are of paramount importance in our understanding of the potential risk factors for lung cancer among women,” said the lead researcher, Dr. Y. Zhang from Xiangya Hospital, Central South University. “Early menarche, early menopause, and a shortened reproductive life span are associated with higher risks of incident lung cancer, especially NSCLC, in subpopulations with specific genetic risk and lifestyle choices.”
This pioneering research emphasizes the importance of screening multiple reproductive factors in identifying potential lung cancer risk among female populations. By understanding these associations, healthcare professionals can develop targeted preventive strategies and interventions to combat lung cancer effectively, Dr. Zhang reported.
About the IASLC:
The International Association for the Study of Lung Cancer (IASLC) is the only global organization dedicated solely to the study of lung cancer and other thoracic malignancies. Founded in 1974, the association’s membership includes more than 8,000 lung cancer specialists across all disciplines in over 100 countries, forming a global network working together to conquer lung and thoracic cancers worldwide. The association also publishes the Journal of Thoracic Oncology, the primary educational and informational publication for topics relevant to the prevention, detection, diagnosis, and treatment of all thoracic malignancies.

About the WCLC:
The WCLC is the world’s largest meeting dedicated to lung cancer and other thoracic malignancies, attracting more than 7,000 researchers, physicians, and specialists from more than 100 countries. The goal is to increase awareness, collaboration, and understanding of lung cancer, and to help participants implement the latest developments across the globe. The conference will cover a wide range of disciplines and unveil several research studies and clinical trial results. For more information, visit https://wclc2023.iaslc.org.
