Public lacks understanding of cancer screening

Most people have inaccurate beliefs about what cancer screening tests can do and what they cannot, suggests a recent study from the US National Cancer Institute.

Just 5.6% of survey respondents scored 100% on four true/false questions about the accuracy and value of cancer screening, the study authors report in the American Journal of Preventive Medicine.

"That's a little bit alarming," said lead author Dr Megan Roberts (PhD), a cancer prevention fellow at the NCI's Division of Cancer Control and Population Sciences in Rockville, Maryland.
