United Nations ? The number of diagnosed cancer cases will more than double between 2000 and 2030, primarily in poorer countries, the director of the International Agency for Research on Cancer said Tuesday.

Dr. Peter Boyle said the reasons for the increase include population growth, longer life expectancy, more people smoking in the developing world and a lack of health care in poor countries.

In 2000, the agency estimated 11 million new cases of diagnosed cancer worldwide, 7 million deaths from cancer and 25 million people living with cancer.

The agency, part of the World Health Organization, expects that by the year 2030, there will be 27 million cases of cancer, 17 million deaths from cancer and 75 million people living with cancer.
