The research, conducted by Dr D. Maxwell Parkin, of the International Agency for Research on Cancer, in Lyon, France, estimated the worldwide burden of cancer in terms of incidence, mortality, and prevalence.
The latest results, based on the most recent available international data, show that in the year 2000 there were 10 million new cases, 6 million deaths, and 22 million people living with cancer.
The most common cancers in terms of new cases were found to be lung (1.2 million), breast (1.05 million), colorectal (945,000), stomach (876,000), and liver (564,000).

The author notes that the profile varies greatly in different populations.
"The evidence suggests that this variation is mainly a consequence of different lifestyle and environmental factors, which should be amenable to preventive interventions," comments Dr Parkin.
"World population growth and aging imply a progressive increase in the cancer burden. Some 15 million new cases and 10 million new deaths are expected in 2020, even if current rates remain unchanged," he concluded.
