Oncotype DX Breast DCIS Score® test

Should I get radiation therapy?

After a diagnosis of non-invasive stage 0 breast cancer (called ductal carcinoma in situ [DCIS]), you and your doctor will need to determine the next steps in your treatment. The Oncotype DX Breast DCIS Score® test provides a score that indicates the probability of whether your cancer will recur and if radiation therapy is right for you.

Which treatment is right for you? Your tumor knows

Just as every patient is different, so is every tumor. The DCIS Score test uses genomics to give you and your doctor important risk information about how your individual tumor will likely behave. And although DCIS is an early, non-invasive form of breast cancer—and rarely life threatening—the DCIS Score test provides valuable insights, including:

  • The 10-year risk of your tumor coming back in the same breast as another DCIS tumor
  • The 10-year risk of your cancer coming back as invasive breast cancer
  • Whether you may benefit from radiation therapy


Reasons to get the DCIS Score test:

Icon ribbon

It was the first clinically validated genomic test available for patients with DCIS

Tests show that tumors with similar clinical features do not necessarily have the same local recurrence risk.

It can provide important insights into determining your treatment decisions

Your DCIS Score result predicts how likely your cancer is to return. Based on a very low score, you may feel comfortable avoiding aggressive surgery or radiation, or vice versa if your score is high.

Icon sand timer

It looks beyond traditional measures for insights into your tumor’s biology

Without the DCIS Score test, doctors can only estimate how likely your cancer is to return by looking at factors such as margin width, tumor size, and tumor grade.

Is the DCIS Score test right for you?

You may be a candidate for the breast DCIS Score test if you meet both of these criteria:

  • You’ve been recently diagnosed with DCIS and are making treatment decisions with your doctor
  • You’ve had a lumpectomy or biopsy

NOTE: If you’ve been diagnosed with stage I-IIIA invasive breast cancer, you may be eligible for the Oncotype DX Breast Recurrence Score® test.
