"An increased focus on prevention - encouraging people to get exercise, quit smoking, and eating a healthy diet - led to a drop in certain types of cancer in some population groups", the IARC said. An analysis of these results, published today in CA: A Cancer Journal for Clinicians, highlights the large geographical diversity in cancer occurrence and the variations in the magnitude and profile of the disease between and within world regions.
One in five men and one in six women worldwide develop cancer during their lifetime, and one in eight men and one in 11 women die from the disease.
Worldwide, the total number of people who are alive within 5 years of a cancer diagnosis, called the 5-year prevalence, is estimated to be 43.8 million.
The agency also explained that in rapidly growing economies, a shift from cancers related to poverty and infections to cancer associated with lifestyles more typical of industrialised countries is observed.
Since lung cancer often develops over decades, any decrease in the disease's frequency from declining smoking rates likely won't be seen for years.
It says more than half of all cancer deaths will occur in Asia, home to 60 percent of the world's population.
Europe accounts for 23.4% of the global cancer cases and 20.3% of the cancer deaths, although it has only 9.0% of the global population.
The number of deaths from these cancers was 2,079 while the total number of prevalent cases (over the past five years) was 13,698, said the report.
Together, these three cancer types were responsible for one third of the cancer cases and mortality burden worldwide.
The top five most frequent cancers for both male and female in India are breast, lip and oral cavity, cervix and uteri, lung, stomach. They are also among the five most risky forms of cancer, representing one third of all cancer incidence and mortality worldwide, according to IARC's GLOBOCAN 2018 database, which provides estimates of incidence and mortality in 185 countries for 36 types of cancer.
This is up from estimated 14.1 million new cancer cases and 8.2 million deaths reported in the agency's last assessment just six years ago.
In Asia and in Africa, cancer deaths (57.3 per cent and 7.3 per cent respectively) are higher than the number identified (48.4 per cent and 5.8 per cent).
The global cancer burden is estimated to have risen to 18.1 million new cases and 9.6 million deaths in 2018. Female breast cancer is the fifth-leading cause of death - 627,000 deaths at 6.6 percent "because the prognosis is relatively favorable, at least in more developed countries".
The survey is based on data from 185 countries and 36 types of cancer. Cervical cancer cases have declined in countries with concerted efforts to screen for it.
That's about four million more cases and one million more deaths than previous estimates.
"In the United Kingdom smoking among women became more prolific later than it did for men, so it's not surprising that we're seeing increasing lung cancer rates now".
In the UAE, colorectum cancer topped the list at 437 cases in 2018 in men followed by prostate at 252, leukaemia at 151, bladder at 146 and lung at 145.
The figures highlighted a worrying rise in lung cancer rates for women - it is now the leading cause of female cancer deaths in 28 countries including Denmark, the Netherlands, China, and New Zealand.
"One of the things that happens with transitions towards high levels of socio-economic development is the environment changes", Freddie Bray, IARC's head of cancer surveillance, told AFP.
