(NaturalNews) Cancer rates are increasing worldwide but especially in economically developing countries, according to a report released by the American Cancer Society in honor of World Cancer Day and published in CA: A Cancer Journal for Clinicians.
According to the report, an estimated 12.6 million new cases of cancer were diagnosed in 2008, and 7.6 million people died from cancer. The majority of those cases - 7.1 million and 4.8 million, respectively - occurred in economically developing countries. The spread of an "affluence" disease such as cancer to poorer countries can be attributed to the increasing adoption of unhealthy behaviors such as smoking, sedentism and poor diet.
The researchers noted that one-third of the cancer deaths in 2008 could have been prevented by simple measures such as people quitting smoking, drinking less, eating better, exercising more and reducing infection risk. That would have saved 7,300 lives per day.
In the developed world, only 10 percent of cancers are caused by infection, but 25 percent are caused by infection in the developing world.
"The worldwide application of existing cancer control knowledge according to the capacity and economic development of countries or regions could lead to the prevention of even more cancer deaths in the next two to three decades," said Otis W. Brawly of the American Cancer Society. "In order to achieve this, however, national and international public health agencies, governments, donors, and the private sectors must play major roles in the development and implementation of national or regional cancer control programs worldwide."
The most common cancers among men in economically developed countries are prostate, lung and colorectal cancers, while breast, colorectal and lung cancers are the most common types in women. In developing countries, cancers of the lung, stomach and liver are the most common types in men, while breast, cervical and lung cancers are the most common in women.
This grim picture is only expected to worsen, with cancer rates expected to increase nearly 100 percent by 2030 due to worsening lifestyle factors and a growing, aging world population.
