Good Day, may all be well and happy always.
I had my mascetetomy done and the reports showed that it is PR and ER nehative. I was told to have a FISH test and to use Herceptin if necessary.
What is FISH TEST and when is it necessary to use herceptin? I heard it is an expensive drug and what is the difference between other normal drugsto treat breast cancer? What is the successful rate by using herceptin ?
Please advice, thanks.
