Health Indicator Report of Cancer Incidence - Breast Cancer

Breast cancer is the most common type of internal cancer diagnosed in women, both in New Mexico and the U.S. Like other forms of cancer, breast cancer is thought to result from multiple environmental and heredity risk factors, with the exact cause of any individual breast cancer most often unknowable. The majority of breast cancers occur after age 50 years, and screening for early stage disease has been shown to be effective in reducing breast cancer mortality in this age group. Screening efficiency in women under age 50 years is less clear since it appears that disease in younger women differs from that in older women, often being more aggressive and more likely to involve hereditary factors.

Breast 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.


The 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.


The estimated population of New Mexico female residents within a specified time period and age group.
