We know more about cancer prevention, detection, and treatment than ever before--yet not all segments of the U.S. population have benefited to the fullest extent possible from these advances. Some ethnic minorities experience more cancer than the majority population, and poor people - no matter what their ethnicity - often lack access to adequate cancer care. This book provides an authoritative view of cancer as it is experienced by ethnic minorities and the medically underserved. It offers conclusions and recommendations in these areas: defining and understanding special populations, and improving the collection of cancer-related data; setting appropriate priorities for and increasing the effectiveness of specific National Institutes of Health (NIH) research programs, to ensure that special populations are represented in clinical trials; and disseminating research results to health professionals serving these populations, with sensitivity to the issues of cancer survivorship. The book provides background data on the nation's struggle against cancer, activities and expenditures of the NIH, and other relevant topics.
