Breast Cancer in India: Incidence More Than Doubled in 3 Decades – Lancet Study

Mumbai: A new global study published in The Lancet Oncology reveals a concerning trend: the incidence of breast cancer in India more than doubled between 1990 and 2023. The research, encompassing 204 countries, projects a substantial further increase in cases by 2050 if key modifiable risk factors aren’t addressed. This rise isn’t happening in isolation. globally, breast cancer remains the leading cause of cancer-related illness and premature death among women.

Rising Incidence and Mortality in India

The study details a significant climb in breast cancer rates within India. In 1990, approximately 13 out of every 100,000 women were diagnosed with breast cancer. By 2023, that number had risen to 29.4 per 100,000. Alongside this increase in diagnoses, the age-standardized mortality rate also saw a worrying jump, increasing from 8.9 to 15.5 deaths per 100,000 – a 74% rise in breast cancer deaths over the same period. This suggests that while more cases are being identified, outcomes aren’t necessarily improving at the same pace.

Globally, an estimated 2.3 million new breast cancer cases and 760,000 deaths occurred in 2023. Researchers predict that, despite advancements in treatment, the number of cases could surge by a third, reaching 3.5 million by 2050. The Indian Express reports that this projected increase isn’t inevitable, but rather a forecast dependent on addressing modifiable risk factors.

Shifting Age Patterns and Economic Burden

While breast cancer traditionally affects older women, the study highlights a concerning trend: an increase in diagnoses among younger women aged 20-54. Between 1990 and 2023, new cases in this age group rose by 29%, while rates among women 55 and older remained relatively stable. This shift suggests changing risk factor profiles, with variations between pre- and post-menopausal women. In 2023, three times as many new cases were diagnosed in women 55 or older compared to those aged 20-54 (161 vs 50 per 100,000 women).

The economic impact of breast cancer is also substantial. In middle-income countries like India, the total economic burden was estimated at $8.13 billion in 2021 and is projected to reach $14 billion by 2030 as incidence continues to climb. This underscores the need for cost-effective prevention and treatment strategies.

Modifiable Risk Factors and Prevention Opportunities

The study identifies six key modifiable risk factors contributing to a quarter of healthy years lost to breast cancer: high red meat intake, tobacco use, high blood sugar levels, and a high Body Mass Index (BMI). Addressing these factors presents significant opportunities for prevention. It’s important to note that “modifiable” doesn’t mean easily changed; it means these are factors individuals and public health initiatives can influence, unlike age or genetics.

Expert Perspectives and the Role of Development

Dr. Jyoti Bajpai, lead medical & precision oncologist from Apollo Hospital, Navi Mumbai, emphasizes that the projected rise in breast cancer burden is not predetermined. “With organized screening, timely diagnostics, and universal access to evidence-based treatment, You can bend the curve,” she states. “The science is ready. The time to act is now.”

Dr. Sudeep Gupta, director of Tata Memorial Centre, points out a correlation between economic development and breast cancer incidence. He notes that as countries develop, changes in reproductive patterns, increased tobacco and alcohol consumption, and other lifestyle factors can contribute to a rise in the disease. NDTV highlights this observation, noting that the breast cancer burden in Western countries has begun to peak, with lower associated mortality rates.

Bridging the Gap in Cancer Care

Dr. Kumar Prabhash from Tata Memorial Hospital, Parel, emphasizes the importance of improving breast cancer detection in underserved countries and bridging the gap in care between developed and developing nations. This requires investment in infrastructure, training, and access to affordable treatment options.

What Comes Next: A Multifaceted Approach

The study’s authors stress that achieving equitable survival rates for all women requires a comprehensive strategy. This includes aggressive prevention efforts targeting modifiable risk factors, robust health systems capable of early diagnosis and comprehensive treatment, and ensuring cancer services are accessible and affordable to everyone. Progress relies on a combination of individual lifestyle changes, public health initiatives, and sustained investment in cancer research and care. Further research is needed to understand the specific risk factors driving the increase in breast cancer among younger women in India and to develop tailored prevention strategies. Ongoing surveillance and data collection are crucial to monitor trends and evaluate the effectiveness of interventions.
