WHO: Lung Cancer Tops Global Cancer Incidence

The International Agency for Research on Cancer, a subsidiary of the World Health Organization, recently released its latest report indicating that there were approximately 20 million new cancer cases worldwide in 2022, with around 9.7 million deaths. Notably, lung cancer accounted for the highest proportion in both categories, with 2.5 million new cases and 1.8 million deaths.

The report highlights that lung cancer, breast cancer, and colorectal cancer had the highest incidence rates globally in 2022. The prevalence of lung cancer as the most common cancer may be linked to the long-standing smoking habits in the Asian region.

On a global scale, there are gender differences in the incidence and mortality rates of cancer. Breast cancer is the most common cancer among women, being the leading cause of cancer-related deaths in females. Conversely, lung cancer is the most prevalent cancer among men and the primary cause of cancer-related deaths in males.

According to a previous domestic survey, the top five cancers with the highest mortality rates in China are lung cancer, liver cancer, stomach cancer, esophageal cancer, and colorectal cancer. Lung cancer tops the list and exhibits the fastest growth rate.

The WHO’s report predicts that by 2050, the global number of new cancer cases will surpass 35 million, marking a 77% increase from 2022. Several factors contribute to the escalating global cancer burden, including aging populations, population growth, and changes in cancer risk factors, some of which are associated with socioeconomic development.

Key factors driving the rise in cancer incidence include smoking, alcohol consumption, and obesity. Air pollution continues to be a major environmental risk factor.
