新数据显示，阑尾癌虽然罕见，但在年轻一代中发病率急剧上升，这成为令人不安的趋势的一部分，即胃肠道癌症的发病年龄比通常预期的要早。以下是外媒报道。

双语文本

The appendix, which plays a role in supporting the immune system, is a small pouch-like organ that is attached to the large intestine at the lower right side of the abdomen. Although cancer of the appendix is rare, diagnoses are rising sharply among Generation X and millennials, according to a new study.

阑尾是一种附着在腹部右下侧大肠上的小袋状器官，对免疫系统具有支持作用。一项新研究表明，尽管阑尾癌很少见，但在X世代和千禧一代中，该病的诊断率正急剧上升。

The data was separated into five-year age groups and showed rising rates in appendix cancer incidence by birth cohort, particularly among people born after 1945, the researchers wrote in the study.

研究人员在研究中写道，数据按五年年龄组划分，结果显示按出生队列划分的阑尾癌发病率呈上升趋势，尤其是1945年以后出生的人群。

Although the new study did not examine specifically why this incidence is on the rise, the researchers say it's "unlikely" to be explained by advances in screening for the disease or diagnostic tools.

虽然这项新研究并未具体探究阑尾癌发病率上升的原因，但研究人员表示，这“不太可能”用疾病筛查或诊断工具的进步来解释。

Rather, the trend may be tied to "environmental exposures that may increase risk for generations now entering mid-adulthood," the researchers wrote. And similar trends "have also been reported for colon, rectal, and gastric cancer," suggesting that possible risk factors may contribute to gastrointestinal cancers as a whole.

研究人员写道，这种趋势可能与“环境暴露因素，这些因素可能会增加如今步入中年的几代人的患病风险”。类似的趋势“也出现在结肠癌、直肠癌和胃癌中”，这表明潜在的风险因素可能会导致整体的胃肠道癌症。
