The Burden of Cancer in the Elderly

BySusan S. Devesa

In 2005, it was estimated that a total of 1,372,910 new cases of invasive cancer would be diagnosed in the United States (1); this estimate does not include the more than 1,000,000 cases of basal and squamous cell skin cancer. The majority of these cancers occur at three sites. In men, over 55% of new cases are due to cancers of the prostate (33%), lung and bronchus (13%), and colon and rectum (10%). In women, 55% of new cases are due to cancers of the breast (32%), lung and bronchus (12%), and colon and rectum (11%).
