Non-communicable diseases are now responsible for many deaths globally and cancer is expected to rank as the leading cause of death and the single most important barrier to increasing life expectancy in every country of the world in the 21st century. The Global Initiative for Cancer Registry Development is an international partnership which supports effectual estimations, as well as the collection and use of local data, to prioritize and evaluate national cancer control efforts.
GLOBOCAN uses the best available sources of cancer incidence and mortality data within a given country however, the validity of the national estimates depends on the degree of representativeness and the quality of source information.
There will be an estimated 18.1 million new cancer cases (17.0 million excluding nonmelanoma skin cancer) and 9.6 million cancer deaths (9.5 million excluding nonmelanoma skin cancer) in 2018.
In both sexes combined, lung cancer is the most commonly diag-nosed cancer (11.6% of the total cases) and the leading cause of cancer death (18.4% of the total cancer deaths), closely followed by female breast cancer (11.6%), prostate cancer (7.1%), and colorectal cancer (6.1%) for incidence and colorectal cancer (9.2%), stomach cancer (8.2%), and liver cancer (8.2%) for mortality.
Lung cancer is the most frequent cancer and the leading cause of cancer death among males, followed by prostate and colorectal cancer (for incidence) and liver and stomach cancer (for mortality).
Among females, breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death, followed by colorectal and lung cancer (for incidence), and vice versa (for mortality); cervical cancer ranks fourth for both incidence and mortality.
