Neoplasms

Abstract Neoplasms are a group of diverse diseases with complex distributions in human populations and with different aetiological factors. Current knowledge of the causes of human neoplasms and the development of control strategies have led to the elaboration of lists of recommendations for their prevention. A comprehensive strategy for cancer control might lead to the avoidance of a sizeable proportion of human cancers, and the greatest benefit can be achieved via tobacco control. Nevertheless, neoplasms will continue to be a major source of human disease and death. Considerable efforts are made in the public and private domains to develop effective therapeutic approaches. Even if major discoveries in the clinical management of cancer patients will be accomplished in the near future, the changes will mainly affect the affluent part of the world population. Prevention of the known causes of cancer remains the most promising approach in reducing the consequences of cancer, in particular in countries with limited resources. Control of tobacco smoking and of smokeless tobacco products, reduced overweight and obesity, moderation in alcohol intake, increased physical activity, avoidance of exposure to solar radiation and control of known occupational carcinogens are the main approaches we currently have to reduce the burden of human neoplasms.
