Stratifies hormone-receptor positive breast cancer patients as low- or high-risk for cancer recurrence and aids in personalized treatment planning.



How will the CanAssist-Breast test results help me?

CanAssist-Breast is a 5 biomarker morphometric IHC test that will help to determine your cancer’s risk of recurrence. You will get a result that classifies your disease as either low- or high-risk for recurrence. A low-risk of recurrence means your cancer has 0 to 9% (average 4.5%) chance of recurring within 5 years. A high risk of recurrence means your cancer has a >10% chance of coming back within 5 years. These results are not a guarantee that your cancer will or will not recur, but will provide valuable information to your doctors which will help them design a customized treatment plan for you.

How long will the report take to arrive?

The report will be dispatched within 10 working days.

Who can use CanAssist-Breast?

All women with <74 years of age with Hormone Receptor (ER/PR) positive Invasive Ductal / Lobular Carcinoma of the Breast, whether node negative or node positive, and Her2 negative can use CanAssist-Breast to determine their risk of recurrence.

How can I order CanAssist-Breast?

CanAssist-Breast can only be ordered upon the recommendation by a treating clinician. You may ask your doctor to run the CanAssist-Breast test on your Breast Cancer sample. For more information on ordering CanAssist-Breast please see the Test Requisition Form or contact the OncoStem team at

Where is CanAssist-Breast test performed?

CanAssist-Breast test is performed at OncoStem’s central laboratory in Bangalore, India.
