Rates of breast cancer vary among different groups of people. Rates vary between women and men and among people of different ethnicities and ages. They vary around the world and across the U.S.
This section provides an overview of breast cancer statistics for many populations.
In 2015, it is estimated that among U.S. women there will be :
Breast cancer in men is rare, but it does happen. In 2015, it is estimated that among men in the U.S. there will be :
Rates of breast cancer incidence (new cases) and mortality (death) are much lower among men than among women . For example, in 2011 (most recent data available) :
Survival rates for men are about the same as for women with the same stage of cancer at the time of diagnosis . However, men are usually diagnosed at a later stage because they are less likely to report symptoms . Learn more about the symptoms of breast cancer in men.
Treatment for men is the same as treatment for women and usually includes a combination of surgery, radiation, chemotherapy, hormone therapy and/or targeted therapy. Learn more about treatment for breast cancer in men.
From the 1940s until the 1980s, breast cancer incidence (new cases) rates in the U.S. increased by a little over one percent each year. In the 1980s, incidence rose greatly (likely due to increased mammography screening), and then leveled off during the 1990s .
The incidence of breast cancer declined in the early 2000s [37-38]. Although mammography screening rates fell somewhat over this same time period, studies show these changes were not likely related to the decline in breast cancer rates [42-43]. The decline appears to be related to the drop in use of menopausal hormone therapy (postmenopausal hormone use) that occurred after the Women's Health Initiative study showed its use increased the risk of breast cancer [37,41-43].
Since 2004, the incidence of breast cancer has remained stable .
Breast cancer mortality (death) rates in the U.S. increased slowly from 1975 to 1990 . Since 1990, breast cancer mortality has decreased by 34 percent . This decline is due to improved breast cancer treatment and early detection .
As mammography screening rates have increased, more cases of breast cancer have been found at earlier stages, when chances of survival are highest.
During the 1980s and 1990s, diagnoses of early stage breast cancer, including ductal carcinoma in situ (DCIS) and conditions such as lobular carcinoma in situ (LCIS), increased greatly. Since the late 1990s, these rates have increased slightly. At the same time, diagnoses of advanced stage (metastatic) breast cancer have remained stable .
Over time, the incidence (new cases) of breast cancer has been higher among white women than among black women.
Since 1990, mortality (death) from breast cancer has declined for both white women and black women . However, breast cancer mortality has declined more slowly among black women than among white women . So, despite incidence being higher for white women, mortality is higher for black women. Figure 1.2 (below) shows these trends.

Over the past 30 years, incidence of breast cancer in men has slightly increased . Breast cancer mortality in men has changed little over time . Learn more about breast cancer in men.
Rates of breast cancer vary across the U.S. Figure 1.5 (below) shows the incidence (new cases) rates of breast cancer for each of the 50 states and Washington, D.C. Figure 1.6 (below) shows breast cancer mortality (death) rates.
Washington D.C. and Connecticut have the highest breast cancer incidence rates and New Mexico has the lowest . Washington D.C., Louisiana and New Jersey have the highest breast cancer mortality rates and Hawaii has the lowest .

Breast cancer is the most common cancer in women worldwide. It is estimated that more than 1.7 million new cases of breast cancer occurred among women worldwide in 2012 (most recent data available) .
Rates of breast cancer around the world vary a great deal. In general, developed countries (such as the U.S., England and Australia) have higher rates than developing countries (such as Cambodia, Nepal and Rwanda).

Women who live in developed countries also tend to have a higher lifetime risk of breast cancer than women who live in developing countries.
Although we don’t know all the reasons for these differences, lifestyle and reproductive factors likely play a large role. Low screening rates and incomplete reporting can make rates of breast cancer in developing countries look lower than they truly are and may also explain some of the difference.

Among women in the U.S., rates of breast cancer incidence (new cases) and mortality (death) vary by race and ethnicity.
Source: American Cancer Society, 2013 
White women have the highest breast cancer incidence overall, while Asian-American and Pacific Islander women have the lowest .
African-American women have the highest breast cancer mortality overall, while Asian-American and Pacific Islander women have the lowest .

Breast cancer is the most common cancer among African-American women. It is also the second leading cause of cancer death among African-American women (lung cancer is the major cause of cancer death among these women) . In 2013 (most recent data available), an estimated 27,060 new cases of breast cancer and 6,080 deaths were expected to occur among African-American women .
Overall, breast cancer incidence in African-American women is lower than in white women. However, for women younger than 45, incidence is higher among African-American women than white women .
In 2011 (most recent data available), breast cancer mortality (death) was 44 percent higher in African-American women than in white women . Although breast cancer survival in African-American women has increased over time, survival rates remain lower than among white women. For those diagnosed from 2004 to 2010, the five-year relative survival rate for breast cancer among African-American women was 80 percent compared to 92 percent among white women . There are many possible reasons for this difference in survival including [46,82]:
Breast cancer screening rates among African-American women are similar to those among white women . Learn more breast cancer screening among African-American women.
Breast and ovarian cancer are somewhat more common among women of Ashkenazi Jewish descent (women with ancestors from Central or Eastern Europe). This is likely due to the high prevalence of BRCA1 and BRCA2 (Breast Cancer 1 and 2) gene mutations in these women. Everyone has BRCA1 and BRCA2 genes, but those who have an inherited mutation in either of these genes are at higher risk for breast and ovarian cancer [48-52].
Like other gene mutations, BRCA1 and BRCA2 mutations are rare in the general population. However, between eight and 10 percent of Ashkenazi Jewish women carry one of these mutations [48,53-54].

Breast cancer incidence (new cases) and mortality (death) rates are lower for Among Asian-American and Pacific Islander women than for non-Hispanic white and African-American women . For example, from 2006 to 2010 (most recent data available) :
Asian-American and Pacific Islander women
84.7 per 100,000
127.3 per 100,000
118.4 per 100,000
11.5 per 100,000
22.7 per 100,000
30.8 per 100,000
Breast cancer mortality rates vary among different Asian-American and Pacific Islander ethnic groups . However, breast cancer is the second leading causes of cancer death in Asian-American and Pacific Islander women (lung cancer is the major cause of cancer death among these women) .
Asian-American and Pacific Islander women have somewhat lower rates of breast cancer screening than African-American and white women . Learn more about breast cancer screening among Asian-American and Pacific Islander women.
Breast cancer is the most common cancer among Hispanic/Latina women . Breast cancer incidence (new cases) and mortality (death) rates for Hispanic/Latina women are lower than for non-Hispanic white women and African-American women . For example, from 2006 to 2010 (most recent data available) :
In 2012 (most recent data available), among Hispanic/Latina women in the U.S., it was estimated that 17,100 new cases of breast cancer would occur and 2,400 women would die from breast cancer . Breast cancer is the leading cause of cancer death in Hispanic/Latina women .
Screening mammography rates among Hispanic/Latina women are similar to rates among non-Hispanic white and African-American women [47,56]. However, Hispanic/Latina women tend to be diagnosed with later stage breast cancers than white women . This may mean that they are less likely to get prompt follow-up after an abnormal mammogram . Learn more about breast cancer screening among Hispanic/Latina women.
In the past, breast cancer in Native Americans was rare. However, the last two decades have seen large increases in both incidence (new cases) and mortality (death) rates for American Indian and Alaska Native women . However, both incidence and mortality remain lower than among white or African-American women. For example, from 2006 to 2010 (most recent data available) :
American Indianand Alaska Nativewomen
90.3 per 100,000
15.5 per 100,000
Breast cancer incidence varies according to where Native American women live. Women who live in Alaska have the highest incidence rates (similar to non-Hispanic white women) and women who live in the Southwest have the lowest incidence rates .
Overall, breast cancer is the third leading cause of cancer death among Native American women . However, like incidence, breast cancer mortality varies according to where Native American women live. Women who live in Alaska and the Southern Plains have the highest mortality rates and women who live in the Southwest have the lowest mortality rates .
Although data are limited, mammography screening rates among American Indian and Alaska Native women are similar to rates among white women . Learn more about breast cancer screening among Native American women.
Although lesbians and bisexual women have a greater risk of breast cancer than other women, it is not because of their sexual orientation. Rather, it is linked to risk factors for breast cancer that tend to be more common in lesbians (such as never having children or having them later in life) [58-60]. Lesbians also tend to have higher rates of obesity and alcohol use, both of which can increase breast cancer risk [58-61].
Early findings suggest that women in a same sex-relationship may have a higher risk of breast cancer death (but not a higher risk of death from any cause) compared to women in a different-sex relationship .
One study found similar rates of screening mammography among lesbians and bisexual women and heterosexual women . However, some findings have shown lesbians and bisexual women may not get regular mammograms [64-65]. The reasons for this are not yet clear. However, lack of insurance, a perceived low breast cancer risk and not seeing a health care provider regularly may all play a role [64-65].
One step lesbians and bisexual women can take is to find a provider who is sensitive to their needs, and to see that provider on a regular basis. Provider visits offer the chance to get routine clinical breast exams and mammograms. These screening tests can find breast cancer early, when the chances of survival are highest.
At this time, data on breast cancer among transgender men and women are too limited to comment on any increased or decreased risk in these populations. If you are transgender, talk to your health care provider about your breast cancer risk. Your provider can assess your situation.

The two most common risk factors for breast cancer are:
All women are at risk for breast cancer. The risk of getting breast cancer increases as you age. Most breast cancers and breast cancer deaths occur in women aged 50 and older .
No matter your age, you should know how your breasts normally look and feel. If you notice any changes, see your health care provider. Learn about the warning signs of breast cancer.
Although rare, younger women can also get breast cancer. Fewer than five percent of breast cancers occur in women under age 40 . However, breast cancer is the leading cause of cancer death (death from any type of cancer) among women ages 20 to 59 .
While breast cancer risk is generally much lower among younger women, certain genetic factors can put some women at a higher risk. Women who are diagnosed at younger ages may have a BRCA1 or BRCA2 gene mutation. Women who carry one of these gene mutations have an increased risk of both breast and ovarian cancers.
