The percentage of U.S. citizens screened for cancer remains below national targets, with significant disparities among racial and ethnic populations, according to the first federal study to identify cancer screening disparities among Asian and Hispanic groups.
The report, Cancer Screening in the United States - 2010, was published by the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI) in the CDC Morbidity and Mortality Weekly Report.
In 2010, breast cancer screening rates were 72.4 percent, below the Healthy People 2020 target of 81 percent; cervical cancer screening was 83 percent, below the target of 93 percent; and colorectal cancer screening was 58.6 percent, below the target of 70.5 percent,
Screening rates for all three cancers were significantly lower among Asians (64.1 percent for breast cancer, 75.4 percent for cervical cancer, and 46.9 percent for colorectal cancer) compared to other groups, the study found. Hispanics were less likely to be screened for cervical and colorectal cancer (78.7 percent and 46.5 percent, respectively) when compared to non-Hispanics (83.8 percent and 59.9 percent, respectively).
Healthy People 2020 sets national objectives for improving the health of all Americans. Such objectives include the use of screening tests recommended by the United States Preventive Services Task Force for breast, cervical and colorectal cancers. Women aged 50-74 years should be screened for breast cancer with a mammogram every two years. Women who have been sexually active for three years or are aged 21-65 years should be screened for cervical cancer with a Pap test at least every three years. Colorectal cancer screening is recommended for average-risk men and women aged 50-75 years, using high-sensitivity fecal occult blood test (FOBT), done at home every year; sigmoidoscopy every five years, with high-sensitivity FOBT every three years; or colonoscopy every 10 years.
To assess the use of currently recommended cancer screening tests by age, race, ethnicity, education, length of residence in the United States, and the source and financing of health care researchers analyzed data from the 2010 National Health Interview Survey, which tracks progress toward the achievement of Healthy People 2020 objectives. For the ethnic subgroups, Asians were classified as Chinese, Filipino, or other Asian and Hispanics as Puerto Rican, Mexican, Mexican-American, Central or South American, or other Hispanic |
