Data reveals a radical gap in survival rates

Breast cancer is the most common cancer in women all over the world, but the chances of survival vary greatly depending on the place where women live, and a new study has appeared¹.

Using global data, the work draws a detailed picture of breast cancer trends and disparities across countries. Although wealthy countries have more diagnoses, low and medium -income countries face higher death rates due to limited access to early detection and treatment.

“This is the best comprehensive global view of breast cancer,” says Rudolph Kax, an epidemic of cancer at the German Cancer Research Center in Heidelberg.

Results – published in Nature Medicine On February 24¹ Health policies can reach all over the world to improve the diagnosis and treatment of breast cancer.

Fidler-Benaoudia and her colleagues looked at the global influence of breast cancer in 2022, the last year of cases of cases and deaths available, and expected influence in 2050 in 185 countries. The researchers have also analyzed trends in breast and deaths during the past ten years in dozens of countries.

In 2022, there were 2.3 million new cases and 670,000 deaths of breast cancer worldwide. However, death rates were higher in the poorest regions of the richer countries (see “global burden”). For example, those under the age of 50 in low -income countries have been more likely to die than breast cancer than those in high -income countries.
