A 'Surge' of Cases

Premium

Because of current population growth trends, the number of cancer cases worldwide could go up to 22.2 million by the year 2030, a 75 percent increase from the 12.7 million worldwide cancer cases reported in 2008, says Miriam Falco at CNN's The Chart blog. According to a study in Lancet Oncology, a "surge" of cases is expected in developing countries, which are currently not ready to handle diagnosing, treating, or preventing the disease, Falco says. Freddie Bray of the International Agency for Research on Cancer and his colleagues looked at the variations in different types of cancer cases and deaths in countries with different levels of socio-economic development. They found that although there has been a decrease in infection-related cancers like stomach, liver, or cervical cancers in wealthier countries, that improvement is being outpaced by new cases in poorer countries associated with reproductive, dietary, or lifestyle factors like tobacco use, Falco adds.
