Pancreatic cancer rates have increased by nearly a fifth since 1999.
自1999年以来,胰腺癌的发病率已增加近五分之一。
Smoking is a known cause of this often-fatal disease yet the number of smokers has reached a record low while pancreatic cancer rates continue to climb. Could the obesity epidemic now be fuelling the increase in pancreatic cancer rates? How does it do this?
众所周知,吸烟是这种常见致命疾病的诱因之一,但现而今,吸烟人数已达历史最低,而胰腺癌的发病率仍在继续攀升。肥胖症是否也在助推胰腺癌发病率的上升?它又是如何做到的?
Obesity causes inflammation, which encourages cell growth and can promote cancer cell mutations. Unsurprisingly, people who have a BMI over 30 before the age of 50 are at a 25% greater risk of dying of pancreatic cancer.
肥胖会引发炎症,从而促进细胞生长、加快癌细胞突变。果不其然,50岁以前身体质量指数超过30的人因胰腺癌而亡的风险会增加25%。
"We've been puzzled by that increase because smoking - a major risk factor for pancreatic cancer - is declining," Dr Eric Jacobs, scientific director at the American Cancer Society, and co-author of the new study has said.
"我们一直对胰腺癌发病率上升一事感到困惑,因为吸烟--胰腺癌的主要危险因素--正在下降,"美国癌症协会的科学主任兼本项新研究的合著者埃里克·雅各布(Eric Jacobs)博士说道。
