The 21st World Cancer Congress, organized by the International Union Against Cancer, was held in China from August 18-21, 2010, with 3,000 delegates from 94 countries and regions around the world attending. In his speech at the Congress, Minister of Health Chen Zhu said that over the past 30 years, China’s cancer mortality rate has increased by 80% and cancer has become the number one cause of death among urban and rural residents in China. The incidence of cancer in China is on a rapid rise, with about 2.6 million cancer cases and 1.8 million deaths each year. At the conference, medical experts focused on topics such as cancer prevention, screening, early detection, early treatment, and hospice care at the Lung Cancer Diagnosis and Treatment Center of Nanjing Military General Hospital Song Yong. Data released by the International Union Against Cancer, where bad habits account for cancer-causing factors, showed that in 2008, 12.7 million people worldwide suffered from cancer and died as many as 7.6 million. More people die from cancer worldwide than AIDS, malaria and tuberculosis combined. If effective measures are not taken, it is expected that by 2030, there will be 26 million new cancer cases and 17 million cancer deaths each year, and low- and middle-income countries will be the “hardest hit” by cancer. Professor David Hill, president of the International Union Against Cancer, pointed out that about 40% of cancers are caused by three factors: lifestyle factors, infectious diseases and other infectious factors, and occupational or environmental factors. Experts say that 1/3 of cancers worldwide are preventable and urgent action is needed by governments, individuals and the medical community to stop the rising number of cancer deaths. Hao Xishan, chairman of the Chinese Anti-Cancer Association and academician of the Chinese Academy of Engineering, pointed out that among the lifestyle factors that trigger cancer, smoking is currently the single largest preventable cancer-causing factor in the world. Of the global lung cancer deaths, 80 to 90 percent are caused by smoking, with the proportion reaching 30 percent in developing countries. The American Cancer Agency reports that bad habits account for 35 percent of cancer-causing factors. In view of this, paying attention to lifestyle prevention can keep many people away from cancer. 80% of patients miss the best time for treatment, according to the survey report “The Status of Access to Cancer Treatment in Low- and Middle-Income Countries – An Important Part of Global Cancer Control” released by the International Union Against Cancer, the survival rate of cancer patients and the type of treatment they can receive are often highly dependent on the country or region in which they live. In low- and middle-income countries, most patients have certain lifestyle habits and lack access to treatments to improve cancer survival, including chemotherapy, surgery and oncology drugs. As many as 80% of cancer patients are late diagnosed and late treated due to different degrees of lack of cancer prevention knowledge and medical services, and miss the best time for treatment. New treatment options and medical devices that can significantly reduce cancer mortality in high-income countries are not available in low- and middle-income countries due to high prices. The current cancer spectrum in China has combined the epidemiological characteristics of cancers in both developing and developed countries, with lung, liver, stomach, esophageal and colorectal cancers, being the five most common cancer killers. The mortality rate of cancer patients in rural areas is significantly higher than that in urban areas, while the high incidence of cancer is mostly concentrated in western regions and rural areas. Therefore, the key to preventing and treating malignant tumors is “first diagnosis + comprehensive”. First diagnosis” includes using advanced and comprehensive cancer diagnostic methods to confirm the diagnosis as soon as possible, and after the diagnosis is confirmed, the hospital with comprehensive treatment strength will receive the diagnosis for the first time and make the best treatment plan; “comprehensive” means “comprehensive treatment of tumor”, which is in essence standardized treatment. The essence of “comprehensive” means “comprehensive treatment of tumor”, which is standardized treatment, together with functional exercise, nutritional adjustment and psychological treatment to really improve the level of tumor treatment.
