How Often Should I Get a Mammogram?

With the conflicting guidelines regarding how often women should get a mammogram, it can be confusing knowing what to believe. To help support you, the medical experts at the Sister Diane Grassilli Center for Women's Health at St. Mary's want to be clear with our three important mammogram recommendations.

1) Talk with your physician
An appropriate screening schedule should be determined collaboratively between you and your physician.

2) Consider annual mammograms
St. Mary’s experts encourage you to get an annual mammogram, because adhering to this schedule increases the chances of early detection, which lead to better cosmetic outcomes and survivorship.
3) Screening guide
All mammogram recommendations should be considered a guide to your screening decision. But they are not meant to be a one-size-fits-all rule.

St. Mary’s Center for Women’s Health has all the technological capabilities to meet your needs. Our advanced technologies result in greater accuracy — even for patients with dense breast tissue — which means fewer follow-up visits or false positives.
