Hello @6750, CAR-T therapy is currently only approved for B-cell ALL and B-cell non-Hodgkin lymphoma. I would like to share a couple of discussions with you here on Connect where other members are posting about ductal invasive carcinoma:

- https://connect.mayoclinic.org/discussion/exemestane-and-side-affects/
- https://connect.mayoclinic.org/discussion/microinvasive-breast-cancer-and-positive-senitel-lympyh-node/

Each discussion has other members you can meet who will understand where you are coming from. I suggest clicking on the links above and sharing your questions and concerns with the members who may be able to both relate and answer some of your questions.
