The number of people around the world who have cancer is growing rapidly. Researchers estimate that there will be 18.1 million new cases of cancer and 9.6 million deaths from the disease in 2018, according to a new report. This was up from 14.1 million new cases and 8.2 million deaths in 2012, the last time the study was conducted.

The report detailing the prevalence and death rates from many different types of cancer was released by the World’s Health Organization’s International Agency for Research on Cancer (IARC). The researchers used data from 185 countries to look at 36 types of cancer for the study. Most countries had an overall rise in the number of cancer cases diagnosed and needing treatment.

Nearly half of the new cancer cases and more than half the cancer deaths worldwide were in Asia. That is not surprising because roughly 60 percent of the world’s population lives in the region. On the other hand, the Americas have 21 percent of cancer incidences despite having only 13.3 percent of the world’s population. Europe accounts for 23.4 percent of cancer cases, but only 9 percent of the world’s population.

IARC said that several factors were contributing to the rising number of cancer cases and deaths. Cancers associated with what researchers call lifestyle choices, such as obesity and drinking, have gone up. An aging population is also contributing to the increase, as cancer risks grow as a person ages.

Cancer is expected to be the top cause of death by the end of the century. It is now estimated that one in five men and one in six women will develop cancer during their lifetime. One in eight men and one in 11 women will die from the disease.

The incidence rate for all cancers combined was about 20 percent higher in men than in women, and deaths were nearly 50 percent higher for men. Lung, breast and colorectal cancers are the ones people get the most, accounting for a third of estimated cancer deaths globally in 2018. IARC’s director Christopher Wild is now calling for efficient prevention and early detection policies to be implemented quickly “to control this devastating disease across the world”.
