Describe current global cancer patterns

Answer 1

• Major reason for the above is the age distribution of the population skewed toward older ages (most cancers are more common in older ages)
• Incidence, adjusting for age is higher in many LMIC than HIC due to infectious diseases in rural areas and risk factors for chronic diseases in urban areas
