In 2018, an estimated 18.1 million new cases cancer will be diagnosed globally, and 9.6 million will die from the disease, according to the latest report from the International Agency for Research on Cancer (IARC).
One in 5 men and one in 6 women worldwide will develop cancer during their lifetime, and one in 8 men and one in 11 women will die from cancer.
Cancer incidence and mortality are rapidly growing worldwide, the report notes.
“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,” the IARC commented in a statement. “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 more typical of industrialized countries.”
Worldwide, the total number of people who are alive within 5 years of a cancer diagnosis (the 5-year prevalence) is estimated to be 43.8 million.
The GLOBOCAN 2018 database is part of the IARC Global Cancer Observatory. It provides estimates of incidence and mortality for 36 types of cancer in 185 countries, as well as for all cancer sites combined.
An analysis of these results was published online September 12 in CA: A Cancer Journal for Clinicians.
“These new figures highlight that much remains to be done to address the alarming rise in the cancer burden globally and that prevention has a key role to play,” commented IARC Director Christopher Wild, MD, in a statement. “Efficient prevention and early detection policies must be implemented urgently to complement treatments in order to control this devastating disease across the world.”
Global Patterns
GLOBOCAN 2018 estimates that almost half of all cases and over one half of related deaths will occur in Asia, partly because almost 60% of the global population resides on that continent. Europe accounts for almost a quarter (23.4%) of the total number of global cases and about a fifth (20.3%) of cancer-related mortality, but it comprises only 9% of the world population. The Americas account for 13.3% of the global population, with 21% of cancer incidence and 14.4% of related mortality.
Conversely, cancer deaths in Asia (57.3%) and Africa (7.3%) are much higher than the incidence (48.4% and 5.8%, respectively) in those regions, largely because of the distribution of cancer types and higher case fatality rates.
The incidence rate for all cancers combined was about 20% higher in men (age‐standardized rate [ASR], 218.6 per 100,000 person-years) than in women (ASR, 182.6 per 100,000), although there was substantial variation across regions.
For men, there was an almost sixfold difference, from 571.2 per 100,000 in Australia/New Zealand to 95.6 per 100,000 in Western Africa. Similar ranges were seen for women, with a nearly fourfold difference, from 362 per 100,000 in Australia/New Zealand to 96.2 per 100,000 in South‐Central Asia.
