Dr. Michelle Holmes of Harvard University, who has studied cancer and lifestyle factors, said people might wrongly think their chances of getting cancer depend more on their genes than their lifestyle.
"The genes have been there for thousands of years, but if cancer rates are changing in a lifetime, that doesn't have much to do with genes," she told The Associated Press in a phone interview from Cambridge, Massachusetts.
Breast cancer is the most common cancer in women. In Europe, there were about 421,000 new cases and nearly 90,000 deaths in 2008, the latest available figures. The United States last year saw more than 190,000 new cases and 40,000 deaths.
A woman's lifetime chance of getting breast cancer is about one in eight. Obese women are up to 60 percent more likely to develop any cancer than normal-weight women, according to a 2006 study by British researchers.
Many breast cancers are fueled by estrogen, a hormone produced in fat tissue. So experts suspect that the fatter a woman is, the more estrogen she's likely to produce, which could in turn fuel breast cancer. Even in slim women, experts believe exercise can help reduce the cancer risk by converting more fat into muscle.
