Study: Most U.S. adults not being screened for cancer

Many adults in the U.S. are not getting the recommended screening tests for colorectal, breast and cervical cancers, according to data published in the latest Centers for Disease Control and Prevention’s (CDC) Morbidity and Mortality Weekly Report. For 2013, screening for these types of cancers either fell behind previous rates or showed no improvement.

Among adults in the age groups recommended for screening, about one in five women reported not being up-to-date with cervical cancer screening, about one in four women reported not being up-to-date with breast cancer screening, and about two in five adults reported not being up-to-date with colorectal cancer screening.

The report found that colorectal cancer testing was essentially unchanged in 2013 compared with 2010. Pap test use in women age 21-65 years was lower than 2,000, and the number of mammography screenings was stagnant, showing little change from previous years.

“It is concerning to see a stall in colorectal cancer screening rates,” said Lisa C. Richardson, M.D., M.P.H., director of CDC’s Division of Cancer Prevention and Control. “We must find new ways to make people and providers aware that getting tested for colorectal cancer could prevent cancer and save their lives.”

Researchers reviewed data from the National Health Interview Survey 2013, which is used to monitor progress toward Healthy People 2020 goals for cancer screening based on the most recent U.S. Preventive Services Task Force guidelines.

The screening data for 2013 show that 58.2 percent of adults age 50-75 years reported being screened for colorectal cancer; 72.6 percent of women age 50-74 had a mammogram; and 80.7 percent of women age 21-65 had a Pap test. All of these percentages are below the Healthy People 2020 targets.

The report found that adults without insurance or a usual source of healthcare generally had the lowest screening test use. For example, fewer than one quarter of adults in these groups reported recent colorectal cancer screening, compared with more than 60 percent of adults with private insurance or a usual source of healthcare.

The authors did report some good news: the proportion of women in the highest education and income groups who were screened for breast cancer exceeded the Healthy People 2020 target, and the proportion of people age 65-75 who were screened for colorectal cancer was also near the target.
