When it comes to breast health, mammograms play a crucial role in early detection and treatment of breast cancer. However, many people do not know the difference between two key types of mammograms: screening and diagnostic. Knowing when and why each type is used can make a difference in your breast health journey, and can avoid frustration if you get signed up for the wrong one. Here’s a breakdown of each to help clarify their roles and what to expect.
Screening Mammograms: Routine Check-Ups for Early Detection
Screening mammograms are preventative tests intended for women who do not have any symptoms or signs of breast cancer. They are typically performed as part of a routine check-up and are the most effective tool for early detection of breast cancer. The goal of a screening mammogram is to catch any abnormalities in breast tissue as early as possible, ideally before they cause noticeable symptoms. The American College of Radiology recommends that every woman begin annual screening mammograms at age 40, although certain elements (such as a strong family history) warrant screening much earlier.
Screening mammograms are a service offered at The Boob Bus, as well as Automated Breast Ultrasounds (ABUS), a non-invasive, painless breast imaging exam that uses sound waves to create 3D images of breast tissue. The ABUS, also known as a dense breast ultrasound, is specifically used as a screen for women whose mammogram indicates “dense” (type C or D) breast tissue.
Diagnostic Mammograms: In-Depth Examination for Specific Concerns
A diagnostic mammogram is a follow-up exam used when there is a specific issue or concern with the breast, such as a lump, pain, nipple discharge, or unusual findings from a screening mammogram. While the diagnostic mammogram uses the same imaging and X-ray technology as the screening mammogram, it provides more detailed views and is tailored to focus on the area(s) of concern. This means diagnostic mammograms may take longer and involve additional images compared to a screening mammogram. There is also a requirement for a radiologist to be on site at the facility performing the diagnostic examination so that results can be provided before the end of the appointment. In addition, a diagnostic mammogram may be combined with a diagnostic ultrasound and/or breast biopsy depending on the specific situation.
At this time, The Boob Bus does not offer diagnostic breast imaging. It is important to be clear about any breast concerns you have before your mammogram so you can be re-booked for the best exam given your needs.
Key Differences Between Screening and Diagnostic Mammograms
FEATURE | SCREENING MAMMOGRAM | DIAGNOSTIC MAMMOGRAM |
PURPOSE | Routine check-up for early detection | Follow-up for specific concerns |
FREQUENCY | According to the ACR, every year (for women over 40 or those with increased risk) | As needed, based on findings or symptoms |
IMAGING DETAIL | Standard two views per breast | Additional, focused images as required |
DURATION | Shorter, usually completed quickly | Longer, more in-depth |
INSURANCE COVERAGE | Often fully covered as preventative | May have additional costs depending on coverage |
RESULTS | 1-2 weeks after the exam | During the exam by the radiologist on site |
When to Get a Screening vs. a Diagnostic Mammogram
If you are 40 years or older, it’s generally advised to begin regular screening mammograms. However, if you are experiencing symptoms such as a lump, pain, or any changes in breast tissue, you should consult your doctor right away, as they may recommend a diagnostic mammogram to investigate further.
The Importance of Both Screening and Diagnostic Mammograms
Both types of mammograms are valuable tools in breast health. Screening mammograms are essential for catching cancer early when it’s most treatable, while diagnostic mammograms provide the necessary clarity and detail when something unusual arises.
Maintaining regular screening appointments and quickly addressing any unusual breast symptoms can help ensure better outcomes and peace of mind.
