DefinitionBreast cancer incidence refers to the number of females newly diagnosed with breast cancer within a specified time period and age group. Measures include 1) the number of newly diagnosed breast cancer cases in women under age 50 years, and 50 years and older; and 2) age-adjusted breast cancer incidence rate in women under age 50 years, and 50 years and older (adjusted by the direct method to the 2000 US standard population). All rates are expressed per 100,000 persons.
NumeratorThe number of breast cancer cases newly diagnosed in New Mexico female residents within a specified time period and age group. The data are based on the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program incidence site recode: 26000. http://seer.cancer.gov/siterecode/.
DenominatorThe estimated population of New Mexico female residents within a specified time period and age group.
Why Is This Important?Breast cancer is the most common cancer diagnosed in women. It is estimated that one in eight women will develop breast cancer sometime during her life. Breast cancer can occur at any age, but most cases occur in women over age 50.
Breast cancer accounts for nearly 15% of newly diagnosed cancers in the U.S. each year and about 7% of annual cancer deaths. This equates to 247,000 cases and over 40,000 deaths. The five-year survival rate is 89.7%. New Mexico has averaged about 1,652 new cases of breast cancer per year between 2010 and 2014. Diagnosis rates have remained steady over recent decades.
Like other forms of cancer, breast cancer is caused by a combination of several environmental and heredity risk factors. Screening mammography can help detect breast cancer at an early stage when treatment is most effective.
