U.S. Cancer Screening Rates Dropping: Study12/27/12
THURSDAY, Dec. 27 (HealthDay News) -- The number of Americans
seeking cancer screening has declined over the past decade, a new
study finds, with less than optimal levels for most types of
Disagreements among the groups that set screening
recommendations, including the U.S. Preventive Services Task Force
and American Cancer Society, along with rising numbers of uninsured
people, may be influencing the decline in screening rates, the
Common screening tests include mammograms for breast cancer, Pap
tests for cervical cancer, sigmoidoscopy and colonoscopy for colon
and rectal cancers, and prostate-specific antigen blood tests for
"As Americans, we need to step up to practicing preventive health care, especially for diseases like cancer, where early detection can literally be the difference between life and death," said lead study author Tainya Clarke, a research associate in epidemiology and public health at the University of Miami Miller School of Medicine.
A large percentage of the general public is still at risk of
late stage cancer diagnoses, she said. "The saying 'early detection
saves lives' is not just a catch phrase," she said. "Adhering to
the screening recommendations of the various governing bodies can
improve prognosis and lead to increased treatment options for
people who are diagnosed."
The report was published online Dec. 27 in the journal
Frontiers in Cancer Epidemiology and Prevention..
To see if recommended guidelines were being followed, Clarke's
team analyzed cancer screening among nearly 175,000 Americans who
took part in the U.S. National Health Interview Survey between 1997
Specifically, they looked at cancer screening rates for
colorectal, breast, cervical and prostate cancers, comparing the
screening rates in the general public to all cancer survivors and a
subgroup of more than 7,500 employed cancer survivors.
They found that most Americans didn't meet recommended cancer
screening goals for most cancers. The exception was colorectal
cancer screening -- about 54 percent of the general public had
colorectal screenings, surpassing the government's "Healthy People
2010" goal of 50 percent.
Cancer survivors, who are at risk of developing the disease, had
higher screening rates and underwent the recommended cancer
screenings for all types of cancer except cervical, which decreased
to 78 percent over the 10-year period. The study also found that
fewer cancer survivors had screenings over the past three
Among cancer survivors, white-collar workers had higher
screening rates than blue-collar workers.
"You really want to get to the cancer before it gets to you," Clarke said. "We know white-collar occupations tend to have more options for less strenuous jobs, yet a larger percentage of blue-collar survivors continue to work despite reports of poorer health."
Policies addressing occupational health and wellness should
carefully evaluate approaches to helping jobs accommodate employees
with illnesses requiring long-term recovery, Clarke said.
"If your job doesn't provide paid sick leave and you don't have long-term disability options, you have to work to survive," she noted. "Medical bills are one of the leading causes of bankruptcy in the United States. If you want continued access to health insurance for reduced treatment costs, you can't really quit."
Dr. Otis Brawley, chief medical officer and executive vice
president of the American Cancer Society, said, "Things are going
to change dramatically because of the Affordable Care Act."
"The obstacles to getting screening are going to change over the next several years," he said. "So think of this study as more of a look back at what was going on in the last 10 years and not a predictor of what might happen in the next 10 years."
Currently, recommendations differ in terms of how often people
should be screened and at what age they should start -- or stop --
undergoing specific tests. It's not always clear to patients which
tests they need or what their insurance will cover.
In light of the confusion that arises from sometimes conflicting
screening protocols, Brawley said it's good for people to know the
risks and benefits of screening.
"The public is starting to get a much better understanding of the fact that there are a series of questions in medicine," he said. "My view has always been that we should let people be aware of these questions and we should let them decide what they want and respect that decision. There are pluses and minuses associated with every one of these tests."
