　　Cancer is feared by everyone. And this fear is reaching epidemic***流行性*** proportions. Not the disease itself — there is no such thing as a cancer epidemic. Except for lung cancer, mostly caused by cigarette smoking ,the incidence rates are leveling off, and in the case of some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety, The earth itself is coming to seem like a huge carcinogen***致癌物***. The ordinary, more or less scientific statement that something between 80 and 90 percent of all cancers are dun to things in the environment is taken to mean that none of us will be safe until the whole environment is “cleaned up.” This is not at all the meaning.

　　The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high proportion of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data indicate there may be special and specific environmental influences, largely based on personal life-style, that determine the incidence of various forms of cancer in different communities — but that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.

　　答案：

　　大家都害怕癌症，這種恐慌正在蔓延開來。倒不是懼怕癌症本身，癌症也並非流行病。除了主要由於抽菸引起的肺癌之外，癌症的發病率不但穩定下來，而且有些還正在減少。但人們卻都談“癌”色變，陷入一種惶恐不安之中。地球本身看上去就越來越像一個巨大的致癌物。有一種多多少少帶點科學性的普遍說法，認為80%到90%的癌症都是由於環境中的物質引起的。也就是說，直到把整個環境都“清潔乾淨”，我們才沒有危險。然而，資料所說明的真正含義根本不是這樣。

　　80%這個資料是基於全球不同地區癌症發病率的差異統計出來的。比如，非洲和遠東地區肝癌比例高，日本胃癌比例高，西歐和北美乳腺癌比例高，但是日本和非洲部分地區乳腺癌病例較少，美洲肝癌病例也較少。這些差異使人難於置信。這些資料表明，不同地區癌症的發病率可能受到環境中某些具體和特殊的影響，其實這種影響主要是由個人的生活方式決定的。所以資料不能說明全部情況。如果把所有病例合計起來，也許各地總體發病率都大致相同。
