While better treatments, early diagnosis and mammogram screenings have dramatically slowed the disease, experts said the focus should now shift to changing behaviors like diet and physical activity. The comments added to a series of findings that lifestyle changes in areas such as smoking, eating, exercise and sun exposure can have a significant effect on all sorts of cancer rates.

"What can be achieved with screening has been achieved. We can't do much more," Carlo La Vecchia, head of epidemiology at the University of Milan, told The Associated Press. "It's time to move onto other things." La Vecchia spoke Thursday on the influence of lifestyle factors at a European breast cancer conference in Barcelona.

Michelle Holmes, a cancer expert at Harvard University, said people might wrongly think their chances of getting cancer are more dependent 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.
