A study looking at blood and tissue samples from women having treatment for early breast cancer (TRANS NEO)

This study is looking at samples from women having chemotherapy or hormone therapy before surgery to remove early breast cancer.

If you have breast cancer, you will have one or more types of breast cancer treatment. We know that people respond to treatment in different ways, and researchers are looking into why this is.

One way of doing this is to study cancer tissue and blood samples to look at proteins and genes that might be linked to the cancer. And then to see if there is a link between these features and how well the treatment works.
