Cancer Health Disparities

Differences by among disadvantaged groups defined by – Race – Ethnicity – Sexuality – Wealth/income – Gender – Disability status

Ways to think about differences among population groups

• Poverty/policies the root cause of disparities??

• Differences by cancer site • Differences by person, place and time • Key determinants of health disparities • Data issues and sources

Poor Breast Cancer Survival in Blacks May Not Be Due to Race

Many factors, including access to health care, could affect outcome, analysis finds

WEDNESDAY, June 23 (HealthDay News) -- Underinsured black breast cancer patients have worse survival outcomes than underinsured white patients, a new U.S. study has found.

Researchers analyzed the records of 574 breast cancer patients treated at Wishard Memorial Hospital in Indianapolis between Jan. 1, 1997 and Feb. 28, 2006, and found that 84 percent of these patients were underinsured.

The study authors noted that black patients had more

advanced breast cancer at diagnosis

and poorer cancer-specific survival outcomes than whites. But after adjusting for age, cancer stage and other factors, they found that race was no longer significantly associated with breast cancer-related death.

In addition, contrary to previous study findings,

black women were as likely as white

women to opt for breast-conserving procedures and " after the completion of the initial treatment -- such as chemotherapy, radiation or hormone therapy -- to lower the risk of cancer recurrence.
