Number of New Cases and Deaths per 100,000: The number of new cases of breast cancer was 124.6 per 100,000 women per year. The number of deaths was 22.6 per 100,000 women per year. These rates are age-adjusted and based on 2007-2011 cases and 2006-2010 deaths.
Lifetime Risk of Developing Cancer: Approximately 12.3 percent of women will be diagnosed with breast cancer at some point during their lifetime, based on 2008-2010 data.
Prevalence of this cancer: In 2011, there were an estimated 2,899,726 women living with breast cancer in the United States.
Survival StatisticsShow More
How Many People Survive 5 Years Or More after Being Diagnosed with Breast Cancer?
Relative survival
statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.
Percent Surviving
5 Years
Based on data from SEER 18 2004-2010. Gray figures represent those who have died from breast cancer. Green figures represent those who have survived 5 years or more.
Additional Information
Survival by Stage
Cancer stage at diagnosis, which refers to extent of a cancer in the body, determines treatment options and has a strong influence on the length of survival. In general, if the cancer is found only in the part of the body where it started it is localized (sometimes referred to as stage 1). If it has spread to a different part of the body, the stage is regional or distant. The earlier breast cancer is caught, the better chance a person has of surviving five years after being diagnosed. For breast cancer, 60.8% are diagnosed at the local stage. The 5-year survival for localized breast cancer is 98.5%.

Breast cancer represents 14.0% of all new cancer cases in the U.S.
14.0%
In 2014, it is estimated that there will be 232,670 new cases of breast cancer and an estimated 40,000 people will die of this disease.
Who Gets This Cancer?
Female breast cancer is most common in middle-aged and older women. Although rare, men can develop breast cancer as well. The number of new cases of breast cancer was 124.6 per 100,000 women per year based on 2007-2011 cases.
Breast cancer is most frequently diagnosed among women aged 55-64.

Who Dies From This Cancer?
Overall, female breast cancer survival is good. However, women who are diagnosed at an advanced age may be more likely than younger women to die of the disease. Breast cancer is the third leading cause of cancer death in the United States. The number of deaths was 22.6 per 100,000 women per year based on 2006-2010.
The percent of breast cancer deaths is highest among women aged 55-64.

Changes Over Time
Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.
Using statistical models for analysis, rates for new breast cancer cases have been stable over 2002-2011. Death rates have been falling on average 1.9% each year over 2001-2010. 5-year survival trends are shown below the figure.
| Year | 1975 | 1980 | 1985 | 1990 | 1994 | 1998 | 2002 | 2006 |

Cancer and the Female Breast
Figure: Breast and Adjacent Lymph Nodes
Click to enlarge.
Inside a woman's breast are 15 to 20 sections, or lobes. Each lobe is made of many smaller sections called lobules. Fibrous tissue and fat fill the spaces between the lobules and ducts (thin tubes that connect the lobes and nipples). Breast cancer occurs when cells in the breast grow out of control and form a growth or tumor. Tumors may be cancerous (malignant) or not cancerous (benign).
