Women should keep getting regular mammograms starting at age 40. That message comes today from Health and Human Services Secretary Kathleen Sebelius. And it's aimed at easing confusion over a recommendation earlier this week from a task force.

The government panel said Monday that most women don't need mammograms in their 40s, and that they should get one every two years starting at age 50. That differs from the longstanding position of the American Cancer Society, which says women should get screening mammograms starting at 40.

Sebelius says the task force doesn't set federal policy, and doesn't "determine what services are covered by the federal government."

Medicare, which covers older Americans and some younger ones who are disabled, provides coverage for an annual mammogram at age 40 and older.
