Common Questions
1. What if my breast cancer does not meet a multiparameter gene expression test's criteria?
If it does not, then that particular test would not be able to be used. Future research findings may support a test’s use in additional patient populations, but currently the criteria are matched with the test’s supporting data.
2. Should I have more than one multiparameter gene expression test done?
This would not generally be necessary. Even though the currently available tests do not overlap each other in the genes that they are evaluating, their findings are all intended to stratify breast cancer recurrence risk.
3. Can a blood test be used to perform a multiparameter gene expression test?
Blood tests can be used to evaluate other aspects of breast cancer but cannot be used to perform multiparameter gene expression tests. What is being evaluated is the tumor's likely behavior so the test requires tumor tissue and cells.
