Hi, thanks for asking in Healthcare Magic.
Many new and effective drugs have come up in the treatment of breast cancer
and so you can still be hopeful.
used in the treatment of cancer, are called "magic bullets" as they target only the cancer cells without affecting normal cells. Transtuzumab is a humanized monoclonal antibody specific for breast cancer who are positive for HER -2/neu receptor. 30% of women with breast cancer are positive for this receptor. It can cause cardiac (heart) toxicity but liver and kidney problems are uncommon.
Drugs like Bevaizumab, Thalidomide
are called angiogenesis
inhibitors and are used in breast cancer. They reduce the blood supply needed for the tumors by inhibiting the formation of new blood vessels. This impairs the growth of tumors.
sensitive tumors Aromatase inhibitors like Anastrazol and Letrazole are available. They reduce the production of estrogen necessary for tumor growth.
I hope this is really useful for the further course of your therapy. Good Luck.
