Many Americans are failing to get recommended cancer screenings, according to a new government report.

Screenings for cervical, breast, and colorectal cancers during 2013 fell behind previous rates or showed no improvement, the new report from the Centers for Disease Control and Prevention (CDC) found.

The report also showed:

• One-in-five women are not up to date with cervical cancer screening.
• One-in-four women are not getting recommended mammograms.
• Two-in-five adults are not undergoing colorectal cancer screening.

Colorectal cancer testing was essentially unchanged in 2013 compared with 2010.

Pap tests in women ages 21-65 was lower than in the year 2000, and the number of mammography screenings was stagnant, showing little change, the report said.

In particular, health officials are concerned about the rate of screening for colorectal cancer, which is largely curable if it is found early.

Without screening, colorectal cancer, which includes colon and rectum cancer, is often diagnosed in its later stages after symptoms have appeared and it has already spread.

“We must find new ways to make people and providers aware that getting tested for colorectal cancer could prevent cancer and save their lives,” said Lisa C. Richardson, M.D., director of CDC’s Division of Cancer Prevention and Control.

A major factor in screening rates could be cost. The report showed that people without insurance generally had the lowest screening rates.
