CanAssist Breast

CanAssist Breast is a prognostic test developed by OncoStem that classifies the patients as ‘low-risk’ or ‘high-risk’ based on the patient’s risk of breast cancer recurrence over five years. CanAssist Breast provides information about the risk of recurrence of early-stage, hormone receptor-positive breast cancer patients. This test analyses critical biomarkers in the tumor to assess the risk of recurrence, and helps oncologists to personalize treatment plans.
