The East African - - OUT­LOOK -

Can­cer bur­den has risen to 18.1 mil­lion new cases and 9.6 mil­lion can­cer deaths in 2018, the World Health Or­gan­i­sa­tion's re­search agency shows The In­ter­na­tional Agency for Re­search on Can­cer's Globo­can 2018 links the in­creas­ing can­cer bur­den is due to sev­eral fac­tors, in­clud­ing pop­u­la­tion growth and age­ing as well as the chang­ing prevalence of cer­tain causes of can­cer linked to so­cial and eco­nomic devel­op­ment. This is par­tic­u­larly true in rapidly grow­ing economies, where a shift is ob­served from can­cers re­lated to poverty and in­fec­tions to can­cers as­so­ci­ated with life­styles. World­wide, the to­tal num­ber of peo­ple who are alive within five years of a can­cer di­ag­no­sis, called the five-year prevalence, is es­ti­mated to be 43.8 mil­lion.
