The International Agency for Research on Cancer (IAC) said recently that due to population increase and lifestyle factors, global cancer cases may increase by 75% by 2030. In 2008, 12.7 million people will have cancer, and by 2230 there will be 22.2 million people suffering from cancer, of which 90 % occurs in the poorest countries. In 2008, half of cancer cases in rich countries were breast cancer. In middle income countries, esophageal cancer, liver cancer, and gastric cancer are relatively common. However, in these two countries, cervical cancer and gastric cancer are cases. All are decreasing. In poor countries, there are more cases of cervical cancer, far more than cancer cases of breast and liver cancer.
