Quiet 'epidemic' has killed half a million middle-aged white Americans

Researchers found that middle-aged white Americans have seen a sharp increase in death rates after 1998, primarily caused by drug and alcohol poisoning, chronic liver disease, and cirrhosis. This trend reverses decades of progress and is not seen in other rich countries or minority groups.

Breast cancer becoming as common among African-American women as among white women

Breast cancer incidence rates have increased among African American women, converging with those of white women. The rise is attributed to ER positive breast cancers and may reflect rising obesity rates. Black women are more likely to be diagnosed at later stages and have poorer survival rates due to lack of access to timely treatment.

Decreases seen in leading causes of death

The age-standardized death rate for all causes combined decreased by 43% between 1969 and 2013, driven by declines in heart disease, cancer, stroke, and unintentional injuries.

Research reveals that young adults, especially women, are not benefiting equally from declining heart disease death rates. Despite improvements in older adults, the annual percentage change in death rates for young men and women showed no improvement between 1990-1999 and has only fallen one percent since 2000.

Study examines breast cancer mortality after ductal carcinoma in situ diagnosis

A study of over 100,000 women with ductal carcinoma in situ (DCIS) found that the 20-year breast cancer-specific death rate was 3.3 percent, higher for women under 35 and black women compared to non-Hispanic white women. Preventing ipsilateral invasive recurrence did not reduce mortality from breast cancer, according to researchers.
