Global Breast Cancer Cases to Cross 3.5 Million by 2050-India Sees 74% Rise in Death Rate -Lancet Study !

Prime Vista News

A Lancet Oncology study projects global breast cancer cases to exceed 3.5 million by 2050. India records a 74% rise in age-standardized death rates since 1990.

Breast cancer remains the most common cancer affecting women worldwide, and new projections suggest the global burden is set to rise sharply in the coming decades. A recent study published in The Lancet Oncology estimates that annual breast cancer cases could increase from 2.3 million in 2023 to more than 3.5 million by 2050.

The report further projects that annual deaths due to breast cancer may rise by 44% from approximately 764,000 deaths to nearly 1.4 million worldwide if current trends continue.

According to the World Health Organization (WHO), around 2.3 million women were diagnosed with breast cancer in 2022 alone, underscoring its position as the leading cancer among women globally.

Findings from the Global Burden of Disease Study

The analysis was conducted by the Global Burden of Disease Study Breast Cancer Collaborators and examined data spanning 1990 to 2023. Researchers highlighted that while high-income countries have benefited from screening programmes and improved treatment access, low- and lower-middle-income nations are now facing a growing share of the burden.

Kayleigh Bhangdia from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, and lead author of the study, said that breast cancer continues to take a profound toll on women and communities worldwide.

She noted that delayed diagnosis, limited access to quality treatment, and higher mortality rates in developing countries threaten to overshadow earlier progress in women’s health.

Breast Cancer Incidence in India

The findings reveal a particularly concerning trend in India. According to the Indian Cancer Society, one in every 28 women in India is likely to develop breast cancer during her lifetime.

In 2023 alone, India reported nearly 2.03 lakh (203,000) new breast cancer cases marking a 477.8% increase compared to 1990. During the same period, the country recorded approximately 1.02 lakh (102,000) deaths, representing a 352.3% rise over three decades.

When adjusted for age, India recorded 29.4 new cases per one lakh women in 2023 a 126.9% increase since 1990. The age-standardized death rate stood at 15.5 per one lakh women, reflecting a 74% rise during the same timeframe.

The data underscores the urgent need for stronger early detection programmes and improved access to affordable treatment in India.

Rising Death Rates in Other Countries

India is not alone in witnessing a surge. The study notes that several countries have experienced significant increases in breast cancer deaths since 1990. Laos recorded the highest rise at 214%, followed by Bangladesh (91%), Vietnam (80%), Indonesia (78%), Japan (52%), the Philippines (41%) and China (37%).

Researchers suggest that lifestyle changes, urbanisation, delayed childbirth, and limited screening infrastructure may be contributing factors in many of these regions.

Pre-Menopausal Breast Cancer Trends

The study also sheds light on age-specific patterns. In 2023, nearly three times as many new cases were diagnosed among women aged 55 and older compared to those aged 20–54.

However, the rate of new cases among younger women (20–54 years) has increased by 29% since 1990, while incidence rates among older women have remained relatively stable. This trend highlights changing risk factors and growing concerns about pre-menopausal breast cancer.

Modifiable Risk Factors

Experts emphasise that a significant portion of breast cancer cases is linked to modifiable lifestyle factors. These include:

• High red meat consumption
• Tobacco use
• Excess alcohol intake
• High body mass index (BMI)
• Elevated blood sugar levels
• Low levels of physical activity

The study indicates that maintaining a healthy lifestyle including avoiding smoking, engaging in regular exercise, maintaining a healthy weight, and reducing red meat intake could prevent over a quarter of healthy years lost due to breast cancer.

Dr Marie Ng, Affiliate Associate Professor at IHME and Associate Professor at the National University of Singapore, stated that more than a quarter of the global breast cancer burden is linked to six modifiable risk factors.

She stressed the importance of public health policies aimed at reducing obesity and improving access to healthier lifestyle options.

Dr Lisa Force, co-senior author from IHME, emphasized the need for stronger healthcare systems worldwide to ensure early diagnosis and comprehensive treatment. She also called for reducing therapy costs and ensuring that universal health coverage includes essential breast cancer care to prevent financial hardship for patients.

The Way Forward

The projections from The Lancet Oncology highlight an urgent need for coordinated global action. Expanding screening programmes, improving awareness, strengthening primary healthcare systems, and promoting healthier lifestyles could significantly alter the trajectory of breast cancer incidence and mortality in the coming decades.

With cases projected to surpass 3.5 million annually by 2050, experts warn that without intervention, the disease could place an even heavier strain on healthcare systems particularly in low- and middle-income countries like India.
