Being overweight or obese 'linked to 10 common cancers' 과체중과 비만은 '10가지 흔한 암과 연관'

By Smitha MundasadHealth reporter, BBC News

Researchers suggest obesity's effects on cancers vary depending on the type of tumour 연구자들은 비만이 암에 미치는 영향은 종양의 타입에 따라 달라진다고 한다

Being overweight and obese puts people at greater risk of developing 10 of the most common cancers, according to research in the Lancet medical journal. 최근 란셋 의학저널에 실린 연구결과에 따르면, 과체중과 비만은 10가지 흔한 암들의 발전을 돕는 위험을 초래한다고 한다.

Scientists calculated individuals carrying this extra weight could contribute to more than 12,000 cases of cancer in the UK population every year. 과학자들은 영국인구중 매년 과체중과 비만인 사람들은 12,000 케이스 이상의 암에 영향을 끼칠 수 있다고 계산하였다.

They warn if obesity levels continue to rise there may be an additional 3,700 cancers diagnosed annually. 과학자들은 비만의 정도가 올라가면 매년 3,700 가지 암들이 추가적으로 진단될 것이라 경고하였다.

The study of five million people is the largest to date to confirm the link. 500만의 사람들에 대한 연구는 상관관계를 입증하는 최대데이타이다.

This variation tells us BMI must affect cancer risk through a number of different processes, depending on cancer type”

Large numbers 큰 규모의 숫자

Doctors often warn being overweight can increase the risk of developing cancer, but this study highlights those forms of the disease where the risk is greatest. 과체중은 암의 진전을 증가시킬 수 있다고 경고한다. 그러나 이번 연구는 최고 위험도인 질병들의 형태를 보여준다.

Led by scientists from the London School of Hygiene and Tropical Medicine researchers gathered data on five million people living in the UK, monitoring changes to their health over a period of seven years.

They found each 13-16kg (2-2.5 stone) of extra weight an average adult gained was linked firmly and linearly to a greater risk of six cancers.

How big this risk was varied depending on tumour type.

• Cancer of the uterus had the highest increased risk 위험도 증가 최고치 보인 자궁암
• gallbladder 담낭
• kidney 신장
• cervix 자궁경관
• thyroid 갑상선
• leukaemia had the lowest rise in risk. 위험도 증가 최저치 보인 백혈병

People who had a high body mass index (calculated using weight and height) were also more likely to develop cancer of the liver, colon, ovaries, and post-menopausal breast cancer.

But the effects for these cancers were less clear-cut and were influenced by individual factors such as the menopause.

Researchers say though obesity was associated with the development of the most common cancers - which represent 90% of the cancers diagnosed in the UK, some showed no link at all.

And there is some evidence to suggest a higher BMI is associated with a lower chance of getting prostate cancer.

Modest risks 적당한 위험

Dr Krishnan Bhaskaran, who led the research, said: "There was a lot of variation in the effect of BMI on different cancers.

"For example, risk of cancer of the uterus increased substantially at higher body mass index, for other cancer we saw a more modest increase in risk or no effect at all.

"This variation tells us BMI must affect cancer risk through a number of different processes, depending on cancer type"

Tom Stansfeld, at Cancer Research UK, said: "Although the relationship between cancer and obesity is complex, it is clear carrying excess weight increases your risk of developing cancer.

"Keeping a healthy weight reduces cancer risk and the best way to do this is through eating a healthy, balanced diet and exercising regularly."
