A new report from the American Cancer Society finds that death rates from breast cancer in the United States have dropped 34% since 1990. But the rate at which new breast cancers are diagnosed increased slightly among African American women from 2006 to 2010, bringing those rates closer to those of white women, who still have the highest diagnosis rates among women ages 40 and older.
The findings are published in Breast Cancer Facts & Figures 2013-2014 and in Breast Cancer Statistics, 2013 in CA: A Cancer Journal for Clinicians. The reports, published every 2 years, provide detailed analyses of breast cancer trends and present information on known risk factors for the disease, factors that influence survival, the latest data on prevention, early detection, treatment, and ongoing research.
Breast cancer is the most common cancer among women in the United States, after skin cancer. It accounts for nearly 1 in 3 cancers diagnosed in women. By the end of 2013, an estimated 232,340 women will be diagnosed with invasive breast cancer and an estimated 39,620 women will die from breast cancer. The risks generally increase with age. Almost 8 of every 10 new breast cancer cases and almost 9 of every 10 breast cancer deaths are in women 50 years old and older.
In January 2012, more than 2.9 million women living in the U.S. had a history of breast cancer. Some of them were cancer-free, while others still had evidence of cancer and may have been undergoing treatment.
Race and Ethnic Factors
White women get breast cancer at a higher rate than African-American women, but African-American women are more likely to get breast cancer before they are 40, and are more likely to die from it at any age. Incidence and death rates for breast cancer are lower among women of other racial and ethnic groups. Asian and Pacific Islander women have the lowest incidence and death rates.
Disparities also exist regarding the prevalence of breast cancer types among racial and ethnic groups. Breast cancers that are estrogen receptor-negative are often harder to treat because they are not likely to respond to hormone therapy. In every age group, African American women have the highest rates of this type of breast cancer. White women have the highest rates of estrogen receptor-positive breast cancer.
Prevention and Early Detection
- Because obesity and excess weight increase the risk of developing breast cancer, the American Cancer Society recommends that women maintain a healthy weight throughout their life. Losing even a small amount of weight has health benefits and is a good place to start.
- Growing evidence suggests that women who get regular physical activity have a 10%-20% lower risk of breast cancer compared to women who get no exercise. Doing even a little physical activity beyond your regular daily routine can have many health benefits.
- Many studies have confirmed that drinking alcohol increases the risk of breast cancer in women by about 7% to 12% for each serving per day. If you do drink alcohol, the American Cancer Society recommends women limit themselves to no more than 1 drink per day.
- A recent study by American Cancer Society researchers found that current smokers had a 12% higher risk of breast cancer than women who never smoked. Research also suggests that risk may be greater for women who begin smoking before they give birth to their first child. Quitting has numerous health benefits.
- To find breast cancer early, when treatments are more likely to be successful, the American Cancer Societyrecommends women 40 and older have a mammogram and clinical breast exam every year, and younger women have clinical breast exams periodically as well (preferably at least every 3 years).
