In 2013, it is estimated that among U.S. women there will be [35]:
Rates of breast cancer among women vary by:
Men
Breast cancer in men is rare, but it does happen. In 2013, it is estimated that among U.S. men there will be [35]:
- 2,240 new cases of breast cancer.
- 410 breast cancer deaths.
Rates of breast cancer incidence (new cases, including new cases of primary breast cancer among survivors, but not recurrence of original breast cancer among survivors) and mortality (death) are much lower among men than among women [35]. For example, in 2009 (most recent data available) [36]:

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 male breast cancer.
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 male breast cancer.
Time trends of breast cancer rates in the United States
Rates of breast cancer over time
From the 1940s until the 1980s, the rate of new cases of breast cancer (called incidence) in the U.S. increased by a little over one percent a year. In the 1980s, incidence rose dramatically (likely due to increased mammography screening), then leveled off during the 1990s.
The incidence of breast cancer declined in the early 2000s [35,37]. 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 [38-39]. 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 risk of breast cancer and heart disease [35,37-40].
Since 2005, the incidence of breast cancer has remained stable [35].
Mammography and rates of early detection over time
As mammography screening rates have increased, more cases of breast cancer have been found at earlier stages, when they are most easily and successfully treated. 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 or dropped slightly [36].
Race/ethnicity and breast cancer rates over time
Since 1975, the incidence of breast cancer has increased among both white women and black women (since 2003, incidence has remained stable). However, during this same time period, mortality rates have decreased for white women, but increased somewhat for black women [36]. Figure 1.2 (below) shows this trend.

Male breast cancer rates over time
Rates of male breast cancer have changed little over the past 30 years [36]. Learn more about male breast cancer.
Geographic variation in breast cancer rates
Worldwide variation
Breast cancer is the most common cancer in women worldwide. It is estimated that more than 1.6 million new cases of breast cancer occurred among women worldwide in 2010 [41]. Rates of breast cancer around the world vary a great deal. In general, developed countries have higher rates than developing countries (see Figure 1.3 below). And, women who live in developed countries tend to have a higher lifetime risk of breast cancer than women who live in developing countries (see Figure 1.4 below). Although we don’t know all the factors that make up 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.

Variation within the United States
Rates of breast cancer vary across the U.S. Figure 1.5 (below) shows the incidence of breast cancer for each of the 50 states and Washington D.C. Figure 1.6 (below) shows breast cancer mortality (death) rates.

Race/ethnicity and breast cancer rates
Within the U.S., breast cancer rates among women vary by race and ethnicity.
Figure 1.7

White women have the highest incidence overall, while Asian American and Pacific Islander women have the lowest [40]. Learn more about breast cancer rates among women of different races/ethnicities:
Migration to the U.S. and breast cancer rates
Immigrants in the U.S. usually have breast cancer rates similar to those in their home country. Over generations however, the daughters and granddaughters of immigrants have a risk similar to U.S. women.
African American women
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, exceeded only by lung cancer [40]. In 2013, an estimated 27,060 new cases of breast cancer and 6,080 deaths were expected to occur among African American women [43].
Breast cancer incidence in African American women is lower than in white women overall. However, for women younger than 45, incidence is higher among African American women than white women [43].
Breast cancer mortality (death) is 41 percent higher in African American women than in white women [35-36]. Although breast cancer survival in African American women has increased in recent decades, survival rates remain lower than among white women. For those diagnosed from 2005 to 2009, the five-year relative survival rate for breast cancer among African American women was 78 percent compared to 92 percent among white women [35-36]. There are many possible reasons for this difference in survival including:
- Biologic and genetic differences in tumors
- Prevalence of risk factors
- Barriers to health care access
- Health behaviors
- Later stage of breast cancer at diagnosis
Breast cancer screening rates among African American women are similar to those among white women [44-45]. Learn more breast cancer screening among African American women.
Ashkenazi Jewish women
Breast and ovarian cancer are somewhat more common among women of Ashkenazi Jewish descent (ancestors who came from Central or Eastern Europe). This is likely due to the high prevalence of mutations in the Breast Cancer 1 and Breast Cancer 2 genes (BRCA1 and BRCA2, respectively) 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 [46-50].
While BRCA1 and BRCA2 mutations are rare in the general population, between eight and 10 percent of Ashkenazi Jewish women carry one of these mutations [46,51-52]. The most common BRCA mutations in these women are 185delAG and 5382insC in BRCA1 and 6174delT in BRCA2 [46,53-56].

Asian American and Pacific Islander women
The most recent estimated breast cancer incidence (2004 to 2008) and mortality (2003 to 2007) rates were lower for Among Asian American and Pacific Islander women than for non-Hispanic white and African American women [40].

Breast cancer is the most common cancer in Korean, Chinese, Filipino and Japanese women in the U.S. [57]. Among Asian American and Pacific Islander women, Native Hawaiian and Japanese women have the highest rates of breast cancer. Native Hawaiian and Samoan women have the highest rates of breast cancer death, exceeding even those in white women [57].

Asian Americans who are new immigrants have lower rates of breast cancer than those who have lived in the U.S. for many years. For those born in the U.S., breast cancer risk is similar to that of non-Hispanic white women (60 percent higher than women born in Asia) [58].
Breast cancer is one of the leading causes of cancer death in most Asian American and Pacific Islander women (lung cancer is the major cause of cancer death among most of these women).
Some data show Asian American and Pacific Islander women have similar rates of breast cancer screening to African American and white women, however other data suggest they have lower rates of screening [44-45]. Learn more about breast cancer screening among Asian American and Pacific Islander women.
Hispanic/Latina women
Breast cancer is the most common cancer among Hispanic/Latina women. The most recent estimated incidence (2004 to 2008) and mortality rates (2003 to 2007) for Hispanic/Latina women were lower than for non-Hispanic white women and African American women [40].

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 [59].
Screening mammography rates among Hispanic/Latina women are now similar to rates among non-Hispanic white and African American women [44-45,59]. However, in the past, Hispanic/Latina women were less likely to have routine mammography screening [36,59]. However, because Hispanic/Latina women tend to be diagnosed with later stage breast cancers than white women, they may be less likely to get prompt follow-up after an abnormal mammogram [59]. Learn more about breast cancer screening among Hispanic/Latina women.
American Indian and Alaskan Native women
In the past, breast cancer in Native Americans was rare. However, the last two decades have seen large increases in both incidence and mortality rates for American Indian and Alaskan Native women. However, rates of both incidence and mortality remain lower than among white or African American women. The most recent estimate of incidence (2004 to 2008) for American Indian and Alaskan Natives was 89 per 100,000 women and mortality (2003 to 2007) was to 18 per 100,000 [40].
Incidence and mortality vary according to where 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 [60].
Although data are limited, mammography screening rates among American Indian and Alaskan Native women are slightly lower than rates among white women [44-45]. Learn more about breast cancer screening among Native American women.
Lesbian, gay and bisexual women
Lesbian and bisexual women have a greater risk of breast cancer than other women, but this is not because of their sexual orientation. Rather, it is linked to risk factors for breast cancer that tend to be more common in these women (such as never having children or having them later in life) [61-63]. Lesbian women also tend to have higher rates of obesity and alcohol use, both of which can increase breast cancer risk [61-64]. Early findings suggest 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 [65].
Lesbian women may be less likely than other women to get routine mammograms and clinical breast exams [66-67]. 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 [66-67].
One step lesbian women can take is to find a provider who is sensitive to their needs, and to see that provider regularly. 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.
Transgender people
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.
Age and breast cancer
The two most common risk factors for breast cancer are:
- Being female
- Getting older
All women are at risk for breast cancer. No matter your age, you should become familiar with how your breasts normally look and feel. If you notice any changes, see your health care provider. Learn about the warnings signs of 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 [40]. Until more is known about prevention, early detection and treatment offer the best defense against dying from breast cancer.
Younger women
Although rare, younger women can also get breast cancer. Five percent of breast cancers occur in women under age 40 [40]. However, breast cancer is the leading cause of cancer death (death from any type of cancer) among women ages 20 to 59 [82].
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 genetic mutation. Women who carry one of these gene mutations have an increased risk of both breast and ovarian cancers. Learn more about inherited gene mutations and cancer risk.
Learn about breast cancer screening for women at higher risk due to a BRCA1 or BRCA2 genetic mutation.
Learn about unique issues for younger women diagnosed with breast cancer.
Pregnant women
Breast cancer is the most common cancer in pregnant and postpartum women. About 13 cases are diagnosed per 100,000 pregnancies [69]. When women are pregnant or breastfeeding, their breasts are naturally more tender and enlarged. This may make it harder to find a lump or notice other changes.
