I am not sure myself what it means if doctors have requested an immunohistochemistry and I hope that you will hear from other members of our community who have had that before and that they will be able to tell you more about their experience.
I would also suggest you give our cancer nurses a call on this free number 0808 800 4040 - their helpline is open Monday to Friday from 9am to 5pm and they will be happy I am sure to tell you more about this and answer questions you may have.
