Breast cancer diagnoses and fatalities are anticipated to rise significantly on a global scale, as reported by the World Health Organization (WHO). This concerning development is linked to several factors, including an ageing population, shifts in lifestyle, and insufficient access to healthcare services. These findings were detailed in the journal Nature Medicine.

Breast cancer statistics

Breast cancer statistics indicate that by 2050, the International Agency for Research on Cancer (IARC), a branch of the World Health Organization, predicts a substantial increase in both diagnoses and deaths related to breast cancer. In 2022, around 2.3 million women were diagnosed with the disease, resulting in approximately 670,000 fatalities, according to IARC's research. It is noted that breast cancer is the most prevalent cancer among women worldwide.

On a global scale, one in every 20 women is expected to receive a breast cancer diagnosis during her lifetime. The IARC analysis forecasts a 38 per cent increase in cases and a 68 per cent rise in deaths over the next 25 years. If current trends persist, the study projects that by 2050, there will be 3.2 million new cases and 1.1 million deaths annually across the globe.

Projected trends

The World Health Organization (WHO) anticipates a notable rise in breast cancer diagnoses and fatalities globally, with low and middle-income nations facing a disproportionate impact. This increase in breast cancer cases is projected to be influenced by factors such as population growth, urbanization, and shifts in reproductive behaviours.

Breast cancer stands as the most prevalent cancer among women worldwide; however, its impact is not uniformly experienced. The highest incidence rates are observed in Western and Northern Europe, along with North America. Conversely, numerous low and middle-income countries struggle with inadequate access to breast cancer screening, diagnosis, and treatment services, resulting in less favourable outcomes.

Recognizing these trends is crucial, and efforts must be directed towards enhancing breast cancer awareness, screening, and treatment options globally, as approximately 25% of breast cancer cases are preventable, according to the study's authors. Strategies such as reducing alcohol consumption, maintaining a healthy weight, and increasing physical activity can contribute to prevention.

“Every minute, four women receive a breast cancer diagnosis globally, and one woman succumbs to the disease, with these figures deteriorating... countries can alleviate or reverse these trends by implementing primary prevention policies and investing in early detection and treatment,” stated Dr. Joanne Kim, an IARC scientist and one of the report's authors.
