Genomic Testing for Breast Cancer

How Does Genomic Testing Guide My Breast Cancer Treatment Decisions

For women diagnosed with early-stage breast cancer, understanding the right treatment approach can feel overwhelming. Genomic testing offers clarity by revealing how your tumor behaves—and MammaPrint is a trusted tool that provides the answers you need to personalize your care.

 

What Is Genomic Testing and Why Does It Matter in Breast Cancer Treatment?

Genomic testing analyzes the activity of specific genes in your tumor to predict how your cancer may behave. This allows your medical team to understand how aggressive your cancer is and whether treatments like chemotherapy may be beneficial.

Unlike genetic testing, which looks for inherited mutations, genomic testing focuses on the tumor itself. It helps answer critical treatment questions based on the unique biology of your cancer.

 

How MammaPrint Genomic Testing Guides Breast Cancer Treatment Decisions

MammaPrint is an advanced genomic test designed for patients with early-stage breast cancer. It examines 70 important genes in your tumor to assess the risk of distant metastasis—whether your cancer is likely to spread.

This clear risk profile equips you and your doctors with actionable insights to personalize your treatment plan.

Importantly, MammaPrint provides four distinct risk categories: Ultra Low, Low, High 1, and High 2. These refined classifications allow for even greater personalization, helping your care team better understand the specific behavior of your cancer and tailor treatment accordingly.

 

Step-by-Step: How MammaPrint Works to Personalize Your Treatment

  1. Tumor Sample Collection – taken from your biopsy or surgery
  2. Gene Activity Analysis – 70 genes are assessed for cancer behavior
  3. Risk Profile Delivered – results fall into one of four categories: Ultra Low, Low, High 1, or High 2
  4. Treatment Plan Created – recommendations are made based on your unique results

Results typically arrive within 5–7 days, helping you and your care team make informed decisions quickly and confidently.

 

Benefits of Using MammaPrint to Guide Treatment Decisions

  • Avoid Unnecessary Chemotherapy – Know if chemo is necessary for your unique tumor biology
  • Clear, Actionable Results – Understand your treatment path with straightforward, evidence-based insights
  • Confidence in Your Care Plan – Decisions are based on your tumor, not just general statistics
  • Global Clinical Validation – MammaPrint is backed by extensive research and trusted worldwide

Understanding Your MammaPrint Results: What They Mean for You

Your results will place you into one of four risk categories:

  • Ultra Low Risk – Extremely low chance of spreading. Minimal treatment may be considered.
  • Low Risk – Lower chance of metastasis. Chemo may be avoidable.
  • High Risk 1 – Intermediate high risk. A more proactive approach may be recommended.
  • High Risk 2 – Highest chance of recurrence. A more aggressive treatment plan may be necessary.

Your oncologist will help you understand these results and create a care plan tailored to your needs.

 

When Should You Consider MammaPrint Genomic Testing?

MammaPrint is ideal for patients who:

  • Have early-stage breast cancer (Stage I or II)
  • Are deciding whether to include chemotherapy in their treatment
  • Want a personalized plan based on their tumor’s biology
  • Need clarity and confidence in their care choices

 

The Future of Personalized Breast Cancer Treatment

Precision medicine is transforming the way we approach breast cancer. Genomic tools like MammaPrint provide deeper insight into how your tumor behaves—making treatments more targeted, effective, and personal.

As research continues to advance, genomic testing will play an even greater role in improving outcomes and reducing unnecessary treatments for breast cancer patients around the world.
