Screening vs. Diagnostic Mammogram: What Is the Difference?

You may have heard the terms "screening mammogram" and "diagnostic mammogram" and assumed they are the same thing. They are not. Understanding the difference matters — for your health, your time, and your insurance.

Screening Mammogram

A screening mammogram is a routine check performed on women with no breast symptoms or complaints. Think of it as a preventive maintenance scan.

Key Facts - Recommended annually starting at age 40 per ACR screening guidelines - Takes about 10-15 minutes - Typically involves 4 images (2 per breast) - Does not require a physician referral in most states (including Florida) - Insurance and Medicare cover screening mammograms at no cost to you

Purpose The goal is to detect cancer before it can be felt — when it is smallest and most treatable. Screening mammography has been proven to reduce breast cancer deaths by 20-40% according to the National Cancer Institute in women who are screened regularly.

Diagnostic Mammogram

A diagnostic mammogram is a detailed follow-up performed when something needs further evaluation. It is a problem-solving exam.

When Is It Ordered? - You had an abnormal screening mammogram (a "callback") - You feel a lump or thickening - You have nipple discharge or skin changes - You have breast pain that is persistent and localized - You are being monitored after a previous breast cancer diagnosis

How It Differs - Takes longer (30-60 minutes) because extra views are taken - Includes spot compression and magnification views for a closer look - A radiologist may be present in real time to guide the technologist - May include a breast ultrasound on the same visit - Requires a physician referral and is billed differently than screening

The Callback: Do Not Panic

About 10% of women are called back after a screening mammogram for additional views. This does NOT mean you have cancer. In fact, fewer than 1 in 10 callbacks result in a cancer diagnosis.

Common reasons for callbacks: - Overlapping breast tissue that needs a clearer view - A small area the radiologist wants to see in more detail - Comparison needed with prior mammograms from another facility - Dense breast tissue obscuring part of the image

If you are called back, a diagnostic mammogram will clarify the finding. Most women leave the same day with reassurance.

3D Mammography Reduces Callbacks

At AMI, we use 3D mammography (tomosynthesis) with Hologic technology for all mammograms. 3D imaging captures the breast in thin slices, allowing the radiologist to scroll through layers of tissue rather than looking at a flat, compressed image.

The result: - Up to 40% fewer callbacks compared to 2D-only mammography - 41% increase in invasive cancer detection - Better accuracy in dense breasts

Insurance and Cost

If you are self-pay pricing, AMI offers transparent, affordable pricing for both screening and diagnostic mammograms. Call us for details.

Which Do You Need?

• No symptoms, routine check → Screening mammogram
• Lump, pain, discharge, or prior abnormality → Diagnostic mammogram (talk to your doctor)
• First mammogram ever → Screening mammogram (no referral needed if you are 40+)
