- A study at the 2023 World Conference on Lung Cancer highlights the concerning rise in cancer cases among Pakistani women, focusing on the impact of reproductive factors.
- Researchers conducted a comprehensive study involving 273,190 participants to explore links between reproductive factors and cancer risk, identifying associations with early menarche, early menopause, shortened reproductive span, and early age at first childbirth.
- Significant findings emphasize the need for healthcare professionals to consider multiple reproductive factors when assessing cancer risk among women, especially in populations with high genetic susceptibility and detrimental behaviours, to develop targeted preventive strategies and interventions.
A recent study unveiled at the 2023 World Conference on Lung Cancer by the International Association for the Study of Lung Cancer has shed light on the concerning rise in this cancer-type among women in Pakistan.
This study, conducted by researchers from Xiangya Hospital in Changsha, Hunan, China, examined the influence of key reproductive factors on lung cancer risk among women, uncovering significant associations.
The research team embarked on a prospective cohort study involving 273,190 participants drawn from the UK Biobank. Their primary aim was to explore the links between various reproductive factors and the likelihood of developing lung cancer.
In this comprehensive investigation, the scientists sought to pinpoint potential risk factors and analyze their impact within specific subgroups, including factors such as age, smoking habits, body mass index (BMI), genetic predisposition, and histological subtypes of lung cancer.
Key Findings on
During the course of the study, which spanned a median follow-up period of 12.0 years, the cohort observed 1,182 cases of lung cancer occurring in women.
The researchers discovered several noteworthy associations between specific reproductive factors and an increased risk of incident lung cancer in women. Notable factors included the early onset of menstruation (menarche before the age of 11), early menopause (menopause occurring at or before the age of 46 or between 47-49 years of age), a shortened reproductive span (lasting until the age of 32 or between 33-35 years), and early age at first childbirth (at or before the age of 20 or between 21-25 years).
These findings are of paramount importance in our understanding of the potential risk factors for lung cancer among women. Early menarche, early menopause, and a shortened reproductive life span are associated with higher risks of cancer, especially NSCLC, in subpopulations with specific genetic risk and lifestyle choices.” Dr. Y.

Intriguingly, the researchers conducted a stratified analysis that revealed the prominence of certain reproductive factors, notably early menopause, shortened reproductive span, and early age at first childbirth.
These factors displayed significantly stronger associations with an elevated risk of cancer, particularly non-small cell lung cancer (NSCLC), among populations with high genetic susceptibility and detrimental behavioural habits.
Implications and Future Directions
This pioneering research underscores the importance of considering multiple reproductive factors when assessing the risk of lung cancer among female populations.
By gaining a deeper understanding of these associations, healthcare professionals can devise targeted preventive strategies and interventions to effectively combat the rising incidence of lung cancer among women in Pakistan.
Dr. Zhang, who presented these findings, emphasized the importance of early detection and tailored approaches to reduce the burden of this disease on affected individuals and the healthcare system.
