미국에서 해마다 10만명의 암환자가 비만이 원인이 되어 발생하는 것으로 추정된다는 연구결과가 나왔습니다.
화와이 암연구센터 the Cancer Research Center of Hawaii)는 미국암연구소the American Institute for Cancer Research)의 지원을 받아 음식섭취(diet )와 질병( disease)의 연관관계를 연구했습니다.
연구결과 자궁내막암의 49%, 식도암의 35%가 과도한 체지방과 연관이 있는 것으로 밝혀졌다고 합니다.
연구자들은 아직까지 비만과 암의 연관 관계가 명확히 규명된 것은 아니지만, 일부에서는 지방조직이 암 성장을 촉진하는 성호르몬 수치를 높이거나 지방이 면역기능을 낮춘다는 주장을 하고 있습니다.
미 질병관리본부에 따르면, 20세 이상의 미국인 성인 가운데 34%가 비만이라고 합니다.

Obesity causes 100,000 US cancers every year: study

WASHINGTON (AFP) – Obesity causes more than 100,000 incidents of cancer in the US every year, the American Institute for Cancer Research said in estimates published Friday.
The group, which funds research on the link between diet and the disease, said 49 percent of endrometrial cancers, which originate in the womb, and 35 percent of esophageal cancers are linked to excess body fat.
“It’s clearer than ever that obesity’s impact is felt before, during and after cancer, it increases risk, makes treatment more difficult and shortens survival,” said Laurence Kolonel of the Cancer Research Center of Hawaii.
Scientists have long seen a link between obesity and certain types of cancer, but the study — extrapolated from US cancer incidence data — is among the first to conclude the link exists on such a scale.
Researchers have yet to pin down the exact link between obesity and cancer, but some have suggested that fat tissue may produce heightened levels of sex hormones that spur cancer growth or that fat lowers immune function.
If the link is proven to be true, cancers could be expected to expected to balloon in tandem with US body sizes.
According to the government-backed Centers for Disease Control, 34 percent of American adults aged 20 and over are obese.
