U.S. Breast Cancer Death Rate Drops

Sept. 25, 2007 -- The American Cancer Society (ACS) today reported that U.S. breast cancer deaths continue to drop, but that decline still hasn't reached all ethnic groups.

That news appears in the ACS' biannual report on breast cancer in the U.S.

According to the report, breast cancer deaths declined by 2.2% annually from 1990 to 2004, partly due to earlier detection and advances in treatment.

But there are racial gaps in those figures, the report also shows.

Breast Cancer Race Gap

The ACS reports that breast cancer deaths dropped 2.4% per year from 1990 to 2004 in white and Hispanic women, compared with 1.6% annually in African-American women.

Women's breast cancer death rates didn't change during that time among Asian-American/Pacific Islanders, American Indians, and Alaska natives.

The precise reasons for those racial patterns aren't clear. Genetics may play a role, but other factors including income and access to medical care are also important.

"A woman today has a lower chance of dying from breast cancer than she's had in decades," says Harmon Eyre, MD, chief medical officer for the ACS, in a news release.

"Unfortunately, not all women are benefiting at the same level," says Eyre, noting that by 2004, breast cancer death rates were 36% higher in African-American women than in white women.

The ACS estimates that about 40,460 U.S. women will die of breast cancer in 2007 -- and that about 2.4 million women living in the U.S. have a history of breast cancer.

But breast cancer isn't U.S. women's leading cancer killer -- lung cancer is -- and heart disease kills more U.S. women than all cancers combined.

Latest Breast Cancer Statistics

In the new report, the ACS predicts that an estimated 178,480 new cases of invasive breast cancer will be diagnosed this year among U.S. women.

Invasive cancer has spread from its starting point into surrounding breast tissue. Most breast cancers are invasive.

The ACS also estimates that 62,030 new cases of in situ breast cancer (cancer that hasn't spread beyond its starting point to other breast tissue) will be diagnosed in 2007.

Breast cancer is far more common among women than men. The ACS predicts that in 2007, about 2,030 cases of breast cancer will be diagnosed in men, accounting for about 1% of all breast cancers.

The ACS estimates that 450 men will die of breast cancer in the U.S. this year.

Breast Cancer Rarer?

Breast cancer is U.S. women's most common cancer (except for skin cancers), but it may be becoming rarer than in the past.

Don't race past that word "may." Undetected breast cancers due to missed mammograms may be contributing to the trend.
