Lack of medical coverage, barriers to early detection and screening, and unequal access to improvements in cancer treatment may contribute to observed differences in survival between African American and white women. In addition, recent NCI-supported research indicates that aggressive breast tumors are more common in younger African American and Hispanic women. This more aggressive form of breast cancer is less responsive to standard cancer treatments and is associated with poorer survival. 26. What is the appropriate measure of screening effectiveness? Reduction in breast cancer mortality (deaths from breast cancer) is the accepted measure of screening effectiveness. Where screening is concerned, assessing improvements in the survival from the time of diagnosis misrepresents the benefit because it is confounded by several biases peculiar to screening: • Lead-time bias: Breast-cancer-specific survival is measured from the time of diagnosis of breast cancer to the time of death.
