Recently, the International Agency for Research on Cancer (IARC) released the latest estimates on the global burden of cancer and predicted the trends of cancer burden for 2040. The GLOBOCAN 2020 database provides estimates for 2020 of incidence and mortality in 185 countries for 36 types of cancer and for all cancer sites combined.
According to the data, the global cancer burden is estimated to have risen to 19.29 million new cases (10.06 million in men and 9.23 million in women), and 9.96 million deaths (5.53 million in men and 4.43 million in women) in 2020.
Worldwide, the new cases for breast cancer(2.26 million) exceed those for lung cancer(2.2 million), and Breast cancer has now surpassed lung cancer as the most commonly diagnosed cancer worldwide.
In China, the cancer burden is estimated to reach 4.57 million new cases (2.48 million in men and 2.09 million in women), and 3 million deaths (1.82 million in men and 1.18 million in women) in 2020.
Follows are the detailed demonstrations of the data:
China Ranks First in Terms of the Number of New Cases
In 2020, the estimated number of newly diagnosed cases is 19.29 million worldwide, of which China has 4.57 million, accounting for 23.7% of the total. The new cases are estimated to occur in China more often than in other countries, in part because China has the biggest population in the world.
The top 10 countries that have the most new cases in 2020 are: China (4.57 million), USA (2.28 million), India (1.32 million), Japan (1.03 million), Germany (0.63 million), Brazil (0.59 million), Russia (0.59 million), France (0.47 million), UK (0.46 million) and Italy (0.42 million).

One of the most obvious changes revealed in the latest global cancer burden data for 2020 is the rapidly increasing number of the newly diagnosed breast cancer, surpassing lung cancer as the most commonly diagnosed cancer worldwide. Breast cancer incidence rates are surging worldwide, largely because of the changing prevalence of risk factors for breast cancer. These risk factors include the postponement of childbearing and having fewer children, which are particularly true in rapidly growing economies, where social and economic transitions are undergoing quickly, as well as greater levels of excess body weight and physical inactivity.
The cancer burden is expected to increase by 50% in 2040 compared to 2020, when the number of the newly diagnosed cases will reach nearly 30 million, due to the future population growth and aging worldwide. This trend will be more conspicuous among those countries that require rapid social and economic development.
The increasing cancer burden has become a global trend, along with the changing common cancer types, which is mainly due to the changing prevalence of certain causes of cancer that is occurring in many countries worldwide. The risk factors are now prevalent in many high-income industrialized countries, which includes smoking, unhealthy diets, obesity and physical inactivity.
The prevention and treatment for cancer need to be embedded into the country’s Health Plans as a key means of reducing the future global cancer burden and bridging the widening gap between the developing and the developed countries.
