The number of women dying worldwide from cancer is expected to rise dramatically

The number of women dying worldwide from cancer is expected to rise to 5.5 million by 2030, roughly the equivalent population of Denmark, according to a new report from the American Cancer Society (PDF).

Those numbers would be an increase of almost 60% from cancer death rates in 2012, when 3.5 million women lost their lives to the disease.

But the biggest leap in deaths from cancer is expected to come from low- and middle-income countries, according to the report presented at the World Cancer Congress in Paris on Tuesday.

Though women in these countries are living longer, they were also found to be adopting riskier habits such as smoking and poor diets.
