单选题Global Cancer Rates to Rise by 50% by 2020 The number of new cancer cases worldwide is expected to increase by 50% by the year 2020. But a new report suggests that as many as a third of new cancers could be avoided by adopting healthier lifestyles and through public health action. The World Cancer Report, released by the International Agency for Research on Cancer, shows that cancer has now emerged as a major public health threat in developing countries as well as rich ones. Overall, cancer was responsible for 12% of all deaths in 2000. But in many countries more than a quarter of all deaths are caused by cancer. The report shows that 10 million new cancers were diagnosed globally in 2000, and that number is expected to rise to 15 million by 2020. Researchers say most of that increase will mainly be due to steadily aging populations in both developed and developing countries and current trends in smoking and other unhealthy habits. "Cancer has emerged as a major public health problem in developing countries for the first time, matching its effect in industrialized (工业化的) countries," said researcher Paul Kleihues, MD, director of IARC, in a news release. "Once considered a 'Western' disease, the Report highlights that more than 50 percent of the world's cancer burden, in terms of both numbers of cases and deaths, already occurs in developing countries." The risk of being diagnosed with cancer in developed countries is double that in less-developed ones. However, the risk of dying from cancer is much higher in developing countries, where 80% of cancer patients already have late-stage incurable tumors (肿瘤) at the time of diagnosis. Researchers say cancer rates have traditionally been higher in developed countries due to greater exposure to tobacco, occupational carcinogens (致癌物), and an unhealthy Western diet and lifestyle. As less-developed countries become industrialized and more prosperous, they tend to adopt the high-fat diet and Iow physical activity levels typically seen in the West, which increase cancer rates.

The working group that drew up the report, however, has expressed some concern about the treatment of children and difficulties faced by some patients in arranging their own transport to travel to emergency centers. Improvements are being sought by the Scottish Office on these issues to improve the quality, fairness, and responsiveness of the system. The inquiry was prompted by the deaths of two babies in Ayrshire after the local cooperative, Ayrshire Doctors on Call, provided telephone advice but declined requests for home visits. Parents of the dead children criticized the cooperative for failing to send out a doctor. The parents supported a campaign that called for automatic home visits to be provided for certain groups of patients, such as children and elderly people. That idea has been rejected by the inquiry team, which said that neither patient nor professional groups accepted the value of policies that would provide automatic home visits. Instead, it is recommended that cooperatives carry out more effective monitoring of treatment for children, including reviewing complaints and critical incidents. The first GP cooperatives were formed three years ago to take over out of hours calls from individual practices, but they were established with different working practices. The report notes that variation exists in transport arrangements, with some cooperatives providing free transport to emergency centers and others requiring people often make their own arrangements. Health board have been ordered to report on the fairness of transport arrangements in their area. Guidelines are also to be introduced to ensure that cooperatives are working to similar high standards. They will include arrangements that will allow patients to make contact with an out of hours service with a single phone call. Initiatives are also planned to help GPs in rural areas who have been unable to benefit from the development of cooperatives. An extra 540 000 is being provided to pay for these developments.
