Why cancer incidence in the Arab counties is much lower than other parts of the world?

Abstract

Despite the relatively increased cancer incidence in the last few years in the Arab countries, it is still far from the figures reported from Western countries. Several mechanisms have been adopted to explain the significant decreased incidence of cancer in the Arab countries, among them fasting, food full of special recipes filled with spices, significant lower rates of smoking and alcohol drinking, and genetic predisposition. Clinical trials are warranted on a large population scales to study, discuss, and verify such mechanisms.
