The Oncotype DX^® breast cancer test is a diagnostic test performed after your original breast cancer surgery. Like other laboratory tests, it must be ordered by an authorised healthcare provider (i.e. your breast cancer surgeon or oncologist). You may use the checklist below to help determine if you are a potential candidate for the Oncotype DX breast cancer test.

You may be a candidate for the Oncotype DX breast cancer test if you are medically eligible for chemotherapy and:

• You have been recently diagnosed with anatomic stage I,II or IIIa invasive breast cancer.
• Your breast cancer is estrogen-receptor positive (ER+) 
• Human Epidermal growth factor Receptor-negative (HER2-)
