WHO: Global cancer patients may increase by 50% in the next 20 years

Release time:


Core reminder: Recently, the American Clinical Oncology Conference ended. According to the Global Cancer Report 2014 issued by the World Health Organization, the number of cancer patients and deaths worldwide increased in 2012, of which nearly half of the new cancer cases occurred in Asia. Most of them are in China, and China ranks first in new cancer cases. The "2012 China Cancer Registry Annual Report" also shows that in the past 30 years, the mortality rate of lung cancer in China has increased by 465, and it has replaced liver cancer as the leading cause of death from malignant tumors in China. Nearly 20 million cancer patients worldwide in 10 years
The report describes and analyzes the overall situation and epidemic trends of 28 cancers in more than 180 countries around the world. The report predicts that the number of cancer cases in the world will show a rapid growth trend, from 14 million in 2012 to 19 million in 2025, and may reach 24 million by 2035, that is, an increase of nearly 50% in 20 years. The report shows that the global cancer burden is increasing at an alarming rate, with an average of 1 in 8 deaths due to cancer. The WHO previously issued a research report warning of a major outbreak of cancer cases in the future, calling on people to adjust their lifestyles, and must consider limiting alcohol and sugar intake, and quitting smoking.
Ji Jiafu, Dean of Peking University Cancer Hospital, said that the incidence of cancer is increasing year by year worldwide, and this is also more significant in my country. In some areas, the mortality rate of cancer has exceeded that of cardiovascular disease and has become the number of human health. Big threat.
Developing countries bear the brunt
The report shows that in 2012, half of the world's new cases occurred in Asia, most of which occurred in China. Among them, about half of the new liver cancer cases occur in China, especially liver cancer caused by hepatitis B. According to the report, the global cancer incidence situation is grim, and the morbidity and mortality are on the rise. Developing countries bear the brunt, accounting for 60% of the global new cases and 70% of the annual deaths.
The prevalence of various cancers is also distributed differently by region. Breast cancer is common among women in most countries, but in Africa, cervical cancer kills more women. According to Wang Mingrong, vice president of the Cancer Hospital of the Chinese Academy of Medical Sciences, about 10% of cancers are caused by genetic factors. In addition, some tumors show stronger familial characteristics, including breast cancer, ovarian cancer, colorectal cancer, etc., while liver cancer and lung cancer do not show obvious familial characteristics, but in some high-risk areas, cancer will also show familial aggregation.
