Breast Cancer Survival Rates Differ Based on Ethnicity, Race

The JAMA Report

Every year, thousands of women are diagnosed with breast cancer. Even among women with small breast cancers, survival rates vary greatly between women of different ethnicities. A study published in JAMA looked at 450,000 women with breast cancer of various stages and sizes, finding that compared to white women, black women were 1.5 to 2 times more likely die of a small breast cancer, while a Chinese or Japanese woman was half as likely to die from a similar tumor. Experts stressed the importance of taking a woman’s ethnicity into account when seeking to provide optimal treatment, noting that the course of the cancer can be very different depending on race and ethnicity.
