Are the number of cancer cases increasing or decreasing in the
world? Q: Are the number of cancer cases increasing or
decreasing in the world? A: Cancer is a leading cause of death
worldwide and the total number of cases globally is increasing.
The number of global cancer deaths is projected to increase 45%
from 2007 to 2030 (from 7.9 million to 11.5 million deaths),
influenced in part by an increasing and aging global population.
The estimated rise takes into account expected slight declines
in death rates for some cancers in high resource countries. New
cases of cancer in the same period are estimated to jump from
11.3 million in 2007 to 15.5 million in 2030. In most developed
countries, cancer is the second largest cause of death after
cardiovascular disease, and epidemiological evidence points to
this trend emerging in the less developed world. This is
particularly true in countries in "transition" or middle-income
countries, such as in South America and Asia. Already more than
half of all cancer cases oc
