TEST ACRONYM

DEXA scan

FULL TERMINOLOGY

Dual-Energy X-ray Absorptiometry Scan

DEFINITION

A DEXA scan can measure the bone mineral density of your whole skeleton, as well as specific points that are more likely to break, such as the hip, spine and wrist. Using a DEXA scan to measure bone mineral density at the hip and spine is considered the most reliable way to diagnose osteoporosis and predict the risk of breaking a bone.

WHEN TEST WOULD BE PERFORMED

Certain breast cancer treatments can speed up bone loss or cause you to lose more bone than you normally would.

You'll probably have a baseline DEXA scan before you start treatment with hormonal therapy or chemotherapy. If you don't, talk to your doctor to see if having one makes sense for you. During follow-up visits during treatment, ask your doctor about your bone health and whether protective measures are right for you.

INFORMATION VALUE

If chemotherapy pushes your body into menopause, bone loss may begin while you're still having treatment and continue after treatment is done. An indication of bone loss can help determine if treatment should be considered.
