Cancer in obese women in the study said as the first result

People have to smoking as a cause of cancer culprit. With the growing obesity, British researchers predict that obesity may be replaced, as human beings, especially women, the number one cancer inducement.

 
Women ran
UK cancer experts 安德鲁雷内汉博 persons and their research team in 30 European countries, statistics of the number of overweight and cancer.

 
The researchers found that in 2002 total of 30 countries in Europe about 200 million cancer patients, of which about 7 million people as overweight or obesity may cause cancer. In 2008, this figure rose to more than 120,000 cases jump, close to double.

 
By sex, the new male cancer cases incentives may be related to overweight or obese accounted for 3.2%, similar cases of women who accounted for 8.6%.

 
Pine tight
A medical conference in Berlin, Germany published similar study also showed that European women are about one-tenth of new cases of cancer associated with overweight or obese, the proportion of men 3 times.

 
Cancer Research UK's data showed the British men's waist circumference increased by an average of 10 years, 3.48 cm, 4.35 cm increase in waist circumference of women.

 
Renee Han said that obesity affects the appearance, but also harmful to health. "People can see clearly that obesity affect breast and endometrial cancer incidence. Obesity caused both by the increase in the proportion of cancer." In addition, obesity may increase the incidence of rectal cancer.

 
Experts say at this stage a quarter of cancer deaths linked to smoking. With the gradual reduction of smokers, the increasing number of obesity, obesity may become the number one cancer causes.

 
Hormones cause trouble
Obesity increases the risk of cancer specific mechanism is not clear. The researchers suspected that obesity-related causes changes in hormone levels.

 
The researchers said the increase in body fat, the body produces more hormones such as insulin and estrogen, may contribute to tumor growth. In addition, the paunchy belly accumulation of a large number of people acids, can cause stomach, intestinal and esophageal changes.

 
However, some researchers believe that short fat will not make surge in cancer risk, "as obesity, smoking does not produce serious consequences."

 
Despite the inconsistent point of view, obesity researchers has called for the declaration of war. Renee Han that need to be developed to help the public to maintain a slim new strategy. "We need to explore the biological means to help people find new ways to stay away from obesity," he said, "just call on the public clearly does not work to lose weight."
