Dear eak2863, There are several different chemotherapy regimens that might be used for treatment of breast cancer. There is not one specific regimen used to treat hormone receptor negative and HER2 negative breast cancer. Treatments that would not be used are the hormone therapies that would be used to treat hormone receptive cancers or medications like
Herceptin or
lapatinib which target the HER2 receptor. The medical oncologist would discuss the chemotherapy regimen best suited to the individual based on evaluation of the entire situation.
