Breast Cancer Her2 positive. They injected me with Perjeta, Herceptin, Taxotere, Carboplatin, Benadryl and a steroid!!! Thank God Chemo is done, now they want to continue with the Herceptin. However, the tumor has NOT shrunk as they claimed it would. I've researched information on Herceptin, and have come to the conclusion it is NOT worth the risk for the extremely low percentage of benefit. (and, so far all of this hasn't done anything but make me sick) Side Effects: Bloody nose, swollen eyelids, runny matted eyes, muscle cramps and twitches, breakouts on my face, bruises under my fingernails, nail pain, diarrhea, constipation, heartburn, back pain, kidney pain, extreme tiredness, extreme weight loss, hair loss, inability to smell, changes in taste, sleep interruption, racing heart.
