癌癥是人類目前面對的最嚴峻考驗之一,，全世界有數(shù)百萬人在與各種癌癥抗爭,，雖然我們現(xiàn)在沒有辦法治愈所有癌癥,，但是最新研究顯示通過努力，在過去30年中癌癥患者死亡率一直穩(wěn)步下降,。
隨著癌癥研究深入和醫(yī)學(xué)技術(shù)進步,，癌癥的治療,、預(yù)防和早期診斷都取得長足進步，癌癥已經(jīng)變得不是那么可怕,。但是一些調(diào)研數(shù)據(jù)并沒有正確反應(yīng)給公眾,。癌癥的死亡率與患者年齡有重要聯(lián)系,，很多報告中都強調(diào)癌癥在老年人中死亡率很高,，而忽略總體情況,。
莫西干州立大學(xué)研究人員考慮到患者年齡與癌癥死亡率間的關(guān)系，將癌癥死亡患者按年齡劃分發(fā)現(xiàn),，自從1925年以來癌癥死亡率一直呈現(xiàn)下降趨勢,，最大降幅可達25.9%。
研究人員還發(fā)現(xiàn)心臟病患者死亡率下降比癌癥死亡率還要明顯,，相關(guān)論文發(fā)表在最新一期《癌癥研究》雜志上,。（生物谷Bioon.com）

The conventional practice of analyzing overall age-adjusted cancer mortality rates heavily emphasizes the experience of older, higher mortality age groups. This may conceal shifts in lifetime cancer mortality experience emerging first in younger age groups. We examined age-specific cancer mortality rates and birth cohort–specific cancer mortality rates in U.S. mortality data recorded since 1955 to assess the effects of age, period, and cohort in secular mortality trends. Cancer mortality and population data were obtained from WHO Statistical Information System. Age-specific cancer mortality rates have been steadily declining in the United States since the early 1950s, beginning with children and young adults and now including all age groups. During the second half of the 20th century, each successive decade of births from 1925 to 1995 experienced a lower risk of cancer death than its predecessor at virtually every age for which such a comparison can be made. A major decline in cancer mortality has been occurring in the United States for the past 50 years, affecting birth cohorts born as long as 80 years ago. Excepting lung cancer, much of this decline has occurred despite relatively stable cancer incidence. These findings suggest that improvements in cancer detection, treatment, and/or prevention have reduced the risk of cancer death across the life span for individuals born in the last three quarters of the 20th century.
