Assay Tests

There are several different tests that can be performed on breast cancer tissue removed during breast biopsy/surgery. The general goal of the tests is to obtain detailed genetic information about the cancer cells. The results can help to a) predict response to particular treatments, b) predict the likelihood of recurrence of the cancer. By looking for changes in a carefully selected group of genes, it is possible to make these types of predictions. The tests (Mammaprint, Oncotype DX, etc.) look at different sets of genes and may be hard to compare directly.
