Under the influence of demographic factors and lifestyle, the frequency of occurrence of cancer will increase to 75 percent by 2030.
So says the report of the International Agency of Cancer Research (IARC). In 2008, the world have registered 12.7 million new cancer cases, while this number by the year 2030 is expected to grow at 22.2 million. About 90 percent of them will be residents of poor countries - AFP reports.
Cancer of breast, lung, colorectal and prostate has been dominant in 2008 in rich countries, whereas poor ones were dominated by cancer of esophagus, stomach and liver. However, in general, in recent years it has been noticed a decline of number of cases of cervix and stomach cancer.
The team of scientists who conducted the study say the number of patients with cancer by the year 2030 could be smaller, if strategies of effective prevention, diagnosis and treatment are developed.
