Obesity will soon become the largest cause of cancer and shift the position of women smoke in triggering cancer, like colon cancer, uterine, and breast cancer. This was stated by Dr Andrew Renehan cancer experts at a conference in Berlin.
According to Renehan, from 300,000 new cancer cases are diagnosed in Britain each year, 13,000 of which are caused by obesity. “Obesity is increasing allowing it to be the largest cause of cancer in women in the next decade,” said Renehan, as quoted dailymail site.
The data collected showed Renehan, 1 in 10 new cases of cancer suffered by women in Europe are caused by being overweight or obese. This amount is three times more than the cases in men. In men, only 3.2% of new cancer cases are caused by overweight or obesity was in women reached 8.6%.
Renehan and his team designed a model to estimate the number of cancers caused by obesity (said to be overweight if body mass index of 25 or more). In 2002, they estimate that 70,000 cases from a total of 2 million cases are diagnosed in 30 countries in Europe, caused by excess weight. In 2008, this number jumped to reach 124,050 cases. Between all types of cancer, cancer of the uterine lining, postmenopausal breast cancer and colon cancer are 3 types of cancer most associated with weight.
How obesity affects cancer risk? According to investigators, the fat tissue influence cancer risk by increasing levels of hormones such as insulin and estrogen. The more fat, the more hormones (like estrogen) produced. This hormone will help the growth of tumors. In addition, people with big belly also has more acid in the stomach. These high acid levels can lead to stomach cancer, colon cancer or esophageal cancer.
Previously, bright researchers, smoking is a cause of 1 in 4 deaths in men and women. However, as with many people who quit smoking, this number goes down and will soon be replaced by obesity. In addition, continued Renehan, the small number of women doing hormone therapy (because of fear of breast cancer risk associated) also reinforce the position of obesity as a cause of cancer.
The use of hormone therapy, menurur Renehan, probably has been covered and debilitating effects of obesity on the incidence of disease. “In women who use hormone therapy, it is unclear the proportion of cancer caused by hormones or obese. Meanwhile in the women not using hormones, the effect of obesity much clearer. ”
Today, bright Renehan, the more easily see the effect of obesity on cancer because the number of users of hormone therapy the less. As a result, the number of cancers caused by obesity is also increasing. “We are not trying to seek sensation, in fact, this number seems even higher.” Therefore, the light Renehan, it helps keep the body in order to stay slim.
