`
`Number of New Cases and Deaths per 100,000: The number of new cases of breast cancer was 124.8 per 100,000 women per year. The number of deaths was 21.9 per 100,000 women per year. These rates
`are age-adjusted and based on 2008-2012 cases and 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 2010-2012 data.
`
`Prevalence of This Cancer: In 2012, there were an estimated 2,975,314 women living with breast cancer in the United States.

`
`Survival Statistics
`How Many People Survive 5 Years Or More after Being Diagnosed with Breast Cancer?
`Relative survival (http://surveillance.cancer.gov/survival/measures.html) 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
`
`89.4%
`
`Based on data from SEER 18 2005-2011. Gray figures represent those who have died from breast cancer. Green figures represent those who have survived 5 years or more.

`
`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 regionalor distant. The earlier breast cancer is caught, the better chance
`a person has of surviving five years after being diagnosed. For breast cancer, 61.1% are diagnosed at the local stage. The 5-year survival for localized breast cancer is 98.6%.

`
`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 124.8 per 100,000 women per
`year based on 2008-2012 cases.

`
`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 fourth leading cause
`of cancer death in the United States. The number of deaths was 21.9 per 100,000 women per year based on 2008-2012.

`
`Trends in Rates
`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 the last 10 years. Death rates have not changed significantly over 2002-2012. 5-year survival trends are shown
`below the figure.

`More About This Cancer
`Cancer and the Female Breast
`
`(http://seer.cancer.gov/i/factsheets/breast-lg.jpg)
`FFigure: Breast and Adjacent Lymph Nodes
`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).
