Annual testing rates between 2005 and 2015 were calculated in all women with and without incident (ie, newly diagnosed) breast and ovarian cancers and in clinically eligible subgroups by family cancer history, personal cancer history, and age at diagnosis. Secular trends were assessed using Poisson regression. Women tested early (2005\u20132008), midway (2009\u20132012), and late (2013\u20132015) in the study period were compared in cross-sectional analyses.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Between 2005 and 2015, annual testing rates increased from 0.6\/1000 person-years (pys) (95% confidence interval [CI]\u2009=\u20090.4 to 0.7\/1000 pys) to 0.8\/1000 pys (95% CI\u2009=\u20090.6 to 1.0\/1000 pys) in women without incident breast or ovarian cancers.

We found no evidence of secular trends in clinically eligible subgroups including women with family history indicating increased hereditary cancer risk, but no personal cancer history.
