According to a report published at the World Cancer Congress in Paris on Tuesday, according to statistics from the International Agency for Research on Cancer, in 2012, there were 6.7 million new cases of cancer worldwide, and the number of deaths. It is 3.5 million cases. Of these, 56% of new cases and 64% of deaths occur in underdeveloped countries. By 2030, there are 9.9 million new cases of cancer worldwide and 5.5 million deaths. The death toll is close to the Danish population, which means that the death toll from cancer will increase by 60% in less than 20 years.
Cancer is largely preventable
As the world's population grows and ages, cancer treatment will be the biggest expense for women in poor and middle-income countries, and these cancers are largely preventable.
Sally Cowal, senior vice president of the American Cancer Society, said that most deaths occur in the young and middle-aged population, placing a heavy burden on families and the national economy. Today, one out of every seven women in the world dies of cancer, and cancer is the second biggest killer after cardiovascular death. Breast cancer, colorectal cancer, lung cancer, and cervical cancer are among the top four cancers, most of which can be detected and blocked early, and early diagnosis can lead to higher success rates.
Spread from developed countries to low- and middle-income countries
In some poorer countries, the proportion of cancer cases diagnosed and treated is significantly lower than in wealthy countries, leading to a larger group of deaths. Therefore, as basic health care becomes better and better, the life expectancy of developed countries is getting longer and longer; and the relative burden of developing countries is getting heavier.
As the economy transforms faster and faster, women in developing countries are increasingly exposed to known cancer risk factors such as lack of physical activity, unhealthy diet, obesity and delayed birth time.
As a result, cancer was once a common disease in high-income countries and is becoming more common worldwide.
Geographical differences make the burden of low- and middle-income countries more and more important
The report also pointed out that due to regional differences, the availability of resources also showed great inequalities in the prevention and treatment of cancer. The highest cancer area is in eastern Asia. For example, in China, there were 1.7 million new cases and 1 million deaths in 2012.
In addition, high-income groups in Europe, the United States, and Asia are still among the highest rates of cancer, but fortunately most of them are able to perform early screening and diagnosis.
The high incidence of deaths is mainly concentrated in low-income and middle-income countries, mainly due to their neglect of diagnosis and treatment. The top ones are Zimbabwe, Malawi, Kenya, Mongolia and Papua New Guinea.
Breast cancer and lung cancer are the most common in high-income and low-income groups. Colorectal cancer is the third most common cancer in developing countries, while cervical cancer is more common in less developed countries. Cervical cancer can be vaccinated with HPV. It is prevented and can be diagnosed early by routine PAP testing.
Breast cancer is the most easily diagnosed cancer in women in more than 140 countries, and cervical cancer is most common in 39 low- and middle-income countries.
It is reported that in 2009, the burden of cancer in the global economy was about 286 billion US dollars (261 billion euros), including treatment and care costs and labor costs of labor loss. Regional differences will make the health care burden of low- and middle-income countries more and more important.
