Indicator Report - Breast Cancer Deaths

Why Is This Important?

Breast cancer is the most commonly occurring cancer in U.S. women (excluding basal and squamous cell skin cancers) and a leading cause of female cancer deaths in both Utah and the U.S. Nationally, deaths from lung cancer surpass deaths from breast cancer; however, breast cancer is the leading cause of cancer death among Utah women. Deaths from breast cancer can be substantially reduced if the tumor is discovered at an early stage. Mammography is currently the best method for detecting cancer early. Clinical trials have demonstrated that routine screening with mammography can reduce breast cancer deaths by 20% to 30% in women aged 50 to 69 years [1-6], and by about 17% in women aged 40 to 49 years [7,8].

We do not yet know exactly what causes breast cancer, but we do know that certain risk factors are linked to the disease. Some of these risk factors include age, socioeconomic status, exposure to ionizing radiation, family history, alcohol, and hormonal influence. Some studies indicate that environmental contaminants such as benzene and organic solvents can cause mammary tumors, but clear links have not been established.

Data Notes

Codes used to define female breast cancer: ICD-10 C50.
Age-adjusted to the U.S. 2000 standard population.

*Use caution when interpreting, the estimate does not meet UDOH standards for reliability.

**The estimate has been suppressed because 1) the relative standard error is greater than 50% or the relative standard error can't be determined or 2) the observed number of events is very small and not appropriate for publication.

^Due to Utah Small Area reclassification, numbers for 'West Valley (East)', 'Kearns', and 'West Jordan (NE)' only include data for 2009-2011.

#Due to Utah Small Area reclassification, numbers for 'West Valley (East) V2', 'Kearns V2', 'Taylorsville (West)', and 'West Jordan (NE) V2' only include data for 2012-2013.
