Cancer1. Cancer, which may arise from any type of cell and in any body tissue, is not a single disease but a large number of diseases classified according to the tissue and type of cell of origin. Several hundred such classes exist, constituting three major subtypes; sarcomas, carcinomas, leukemias and lymphomas.2. A number of factors produce cancer in a proportion of exposed individuals. Among these factors are heredity, viruses, ionizing(离子)radiation, chemicals, and alterations in the immune system. For a long time these various factors seemed to work in different ways, but now researchers are studying how they might interact.3. More than 1,350,000 new cases of cancer occur in the United States each year. It is the second leading cause of death in the nation, accounting for about 550,000 deaths annually. The incidence of cancer varies enormously among different geographic areas. The age-adjusted death rate from all cancers in males is 310. 9 per 100,000 in Luxembourg (the highest) as Compared to 37. 5 in El Salvador (the lowest). For women it is 175.2 in Denmark and 48.7 in El Salvador. The figures for the United States are 216. 6 per 100,000 men and 136.5 per 100,000 women.4. The principal approach to curing cancer is to remove all of the malignant (恶性的) cells by a surgical operation. In the past this meant the removal of all of the involved tissue and as much tumors, notably cancer of the breast, this is not always necessary. However, it may help to relieve symptoms.5. The most important preventive measure in controlling cancer is stopping tobacco use, which is the cause of 30 percent of all deaths from cancer. A large reduction might follow better diet: optimal (适当的)calorie intake to avoid obesity (肥胖), reduction of calories form fat to 20 percent of the diet, reduction of redmeat intake, and increased intake of dietary fiber and protective foods.A. Causes of cancerB. Types of cancerC. Control cancerD. The attitude faced to cancerE. Mortality Rate from cancerF. Treating cancer by surgery
Passive smoking is workplace killer Pressure mounted on Britain on Monday to take action on 【51】 smoking with new research showing second, hand smoke 【52】 about one worker each week in the hospitality industry. Professor Konrad Jamrozik,of Imperial College in London, told a conference on environmental tobacco that second-hand 【53】 kills 49 employees in pubs, bars, restaurants and hotels each year and contributes to 700 deaths from lung cancer, heart 【54】 and stroke across the total national work force. "Exposure in the hospitality 【55】 at work outweighs the consequences of exposure of living 【56】 a smoker for those staff," Jamrozik said in an interview. Other 【57】 have measured the levels of exposure to passive smoking but Jamrozik calculated how it would translate into avoidable deaths. His findings are 【58】 on the number of people working in the hospitality industry in Britain, their exposure to second, hand smoke and their 【59】 of dying from it. Jamrozik said me findings would apply to 【60】 countries in Europe because, to a greater or 【61】 extent, levels of smoking in the community are similar. Professor Carol Black, president of the Royal College of Physicians, which sponsored the meeting, said the research is proof of the need for a ban on smoking in 【62】 places. "Environmental tobacco smoke in pubs, bars, restaurants and other public places is 【63】 damaging to the health of employees as well as the general public," she said in a statement. " Making these places smoke, free not only protects vulnerable staff and the public. It will 【64】 help over 300,000 people in Britain to stop smoking completely," she added. Ireland recently became the first country to introduce a national ban on smoking in public 【65】 .
