Breast Cancer Cases in India More Than Double Since 1990, Lancet Study Warns
A comprehensive 204-country study published in The Lancet Oncology has revealed a dramatic surge in breast cancer incidence across India, with cases more than doubling between 1990 and 2023. The research, conducted by the Global Burden of Disease Study Breast Cancer Collaborators, projects another substantial global increase by 2050 unless urgent action is taken to address key modifiable risk factors.
Alarming Rise in Incidence and Mortality
The study's data for India is particularly stark. The incidence rate climbed from 13 cases per 100,000 women in 1990 to 29.4 per 100,000 in 2023. In the same period, the age-standardised mortality rate increased from 8.9 to 15.5 per 100,000, representing a 74% rise in breast cancer deaths in the country.
Globally, breast cancer remains the leading cause of cancer-related illness and premature death among women. In 2023 alone, there were an estimated 2.3 million new cases and 760,000 deaths worldwide. The Lancet study warns that by 2050, global cases could rise by a third to approximately 3.5 million, despite ongoing advances in medical treatment and technology.
Age Patterns and Economic Burden
The research highlights significant age-related trends. In 2023, women aged 55 or older were diagnosed with three times as many new breast cancer cases (161 vs. 50 new cases per 100,000 women) compared to women aged 20-54. However, rates of new cases have risen by 29% since 1990 among younger women (20-54), while rates in older women have not changed substantially. These shifts reflect evolving age patterns and changes in risk factors that differ between pre- and post-menopausal women.
The economic impact is also severe. For middle-income countries like India, the total economic burden of breast cancer was estimated at $8.13 billion in 2021 and is projected to rise to $14 billion by 2030 as incidence continues its upward trajectory.
Modifiable Risk Factors and Prevention Opportunities
A critical finding of the study is that over a quarter of healthy years lost to breast cancer are attributable to six modifiable risk factors. These include:
- High red meat intake
- Tobacco use
- High blood sugar levels
- High Body Mass Index (BMI)
- Alcohol consumption
- Physical inactivity
This presents a significant opportunity for preventive public health strategies. "The projected rise in breast cancer burden by 2050 is not fate—it's a forecast, and, therefore, preventable. This analysis is a policy blueprint. With organized screening, timely diagnostics, and universal access to evidence-based treatment, we can bend the curve. The science is ready. The time to act is now," emphasized Dr. (Prof.) Jyoti Bajpai, lead medical & precision oncologist from Apollo Hospital, Navi Mumbai.
Expert Insights and Global Disparities
Dr. Sudeep Gupta, Director of Tata Memorial Centre, noted the correlation between development and cancer incidence. "With increased levels of development, there is often a concomitant rise in the incidence of some cancers; in India, it is breast cancer. There is a change in reproduction patterns, an increase in tobacco and alcohol use, among other reasons that have been seen across the globe," he explained.
The study also reveals a concerning global disparity. While breast cancer burden in Western nations has peaked and associated deaths are lower, developing countries like India face escalating challenges. "This publication highlights the improvement in breast cancer detection in underprivileged countries, but also provides us the insight into the gap between the developed and the developing countries which we need to bridge," said senior medical oncologist Dr. Kumar Prabhash from Tata Memorial Hospital, Parel.
A Call for Comprehensive Action
The authors conclude that meaningful progress requires a multi-faceted approach:
- Aggressive prevention strategies targeting modifiable risk factors.
- Well-functioning health systems capable of early diagnosis and comprehensive treatment.
- Making cancer services both accessible and affordable to all segments of society.
Ensuring all women have an equal chance to survive breast cancer demands immediate and coordinated action from policymakers, healthcare providers, and communities worldwide.
