Which disease expected to rise most by 2040?

The correct answer is Cancer. Projections from leading health organizations, including the World Health Organization (WHO), indicate that the incidence and mortality rates of cancer are expected to rise most significantly by 2040. This anticipated increase is attributed to factors such as an aging global population, changing lifestyles, and improved diagnostic capabilities that detect more cases.

• Options B and C (Malaria and HIV) are serious global health challenges, but due to ongoing prevention, treatment, and control efforts, their projected rise in incidence by 2040 is not expected to surpass that of cancer. Option D is incorrect as a rise is expected.
