Show Female Breast Cancer (ICD-9 Codes: 174) (1994 Total Deaths from Female Breast Cancer = 195) The incidence rate for female breast cancer is increasing in Utah and the U.S. Between 1981 and 1993, Utah's incidence rate rose 38%. From 1981 to 1991, the U.S. rate increased 24%. Rates of incidence and deaths from female breast cancer are slightly lower for Utah than for the U.S., although the gap appears to be narrowing. In 1991, Utah rates for incidence and mortality had closed to within 92% of national rates. Mortality rates have remained fairly stable even as the incidence rates have risen. This may reflect increased detection at an earlier age resulting in increased treatment efficacy, as well as improved treatment. Table 32.

Early pregnancies may also reduce the risk of breast cancer. The higher fertility rate in Utah may help partially explain why Utah's breast cancer rates are below the national average. Utah has a relatively low rate of breast cancer incidence and mortality. However, in 1991 and 1992 Utah was below the national median in the percentage of women 18 and older who reported ever having a mammogram. Although the percentage increased in 1993, Utah still ranked last out of all 50 states in the percentage of women reporting having had a mammogram. Breast cancer death rates can be reduced by early detection through monthly self-examination and yearly mammograms. Table 33.
