阿司匹林能降低胃癌肠癌死亡率
[font=Verdana, Arial, Tahoma][size=14px][b]Taking aspirin every day can reduce the chance of developing or dying from bowel and stomach cancers, a review of all available evidence suggests.[/b][/size][/font][font=Verdana, Arial, Tahoma][size=14px][b]已有的所有证据都表明，每天服用阿司匹林可以降低肠癌和胃癌感染率或死亡率。[/b][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]And scientists predict if everyone aged 50 and above in the UK took the drug for 10 years, some 122,000 deaths could be prevented over two decades. [/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]But they warn [url=http://www.enread.com/news/cultureandedu/97622.html]aspirin[/url] can cause internal bleeding and say medical advice must be sought before using it.[/size][/font]

[font=Verdana, Arial, Tahoma][size=14px][b]Weighing up benefits[/b][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Scientists examined some 200 studies investigating the benefits and harms of taking aspirin - an area of continuing medical debate. [/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]They found the drug reduced the number of cases and deaths from bowel, stomach and oesophageal [url=http://www.enread.com/news/cultureandedu/97622.html]cancer[/url] by some 30-40%.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]There was weaker and more variable evidence that the drug reduced deaths from breast, prostate and lung cancer too. [/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]And the study found people needed to take the drug for at least five years to see any benefits.[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Prof Jack Cuzick, at Queen Mary University of London, who led the research, urged all healthy people aged 50 and above to consider taking a small dose (75mg) of the drug every day for a decade. [/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Researchers predicted if 1,000 individuals aged 60 took the drug for 10 years, a further decade later there would be:[/size][/font]
[font=Verdana, Arial, Tahoma][size=14px][i] 16 fewer deaths from cancer [/i][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px][i] One fewer death from heart attack[/i][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px][i] Two extra deaths from bleeding[/i][/size][/font]
[font=Verdana, Arial, Tahoma][size=14px]Prof Cuzick, who has been taking aspirin for four years, said: "Whilst there are some serious side-effects that can't be ignored, taking aspirin daily looks to be the most important thing we can do to reduce cancer after stopping smoking and reducing [url=http://www.enread.com/news/cultureandedu/97622.html]obesity[/url], and will probably be much easier to implement."[/size][/font]
