The incidence of cancer varies significantly across different regions of the world. For instance, high-income countries tend to have higher rates of cancers such as breast, prostate, and colorectal cancer, likely due to lifestyle factors and access to diagnostic technologies. In contrast, low- and middle-income countries often see higher rates of cancers related to infectious agents like cervical cancer and liver cancer. Geographic disparities in cancer can be influenced by factors such as environmental exposures, healthcare infrastructure, and cultural practices.
