The Global Burden of Cancer
Cancer is one of the leading causes of death worldwide, with its prevalence and impact continuing to rise. According to the World Health Organization (WHO), cancer accounted for nearly 10 million deaths in 2020, making it the second-leading cause of mortality globally, after cardiovascular diseases. The most common types of cancer include:
Lung Cancer: The leading cause of cancer-related deaths, responsible for approximately 1.8 million deaths annually.
Colorectal Cancer: The third most common cancer, with over 1.9 million new cases and 935,000 deaths in 2020.
Breast Cancer: The most common cancer among women, with 2.3 million new cases and 685,000 deaths in 2020.
Prostate Cancer: A leading cancer among men, with 1.4 million new cases and 375,000 deaths in 2020.
Stomach Cancer: The fifth most common cancer, with 1.1 million new cases and 769,000 deaths in 2020.
The
global cancer burden is expected to increase significantly in the
coming decades due to population growth, aging, and lifestyle changes.
By 2040, the number of new cancer cases is projected to rise to 28.4
million, a 47% increase from 2020.
