I am half way through my course of Herceptin. I had 4 cycles with perjeta and chemo intravenously, now i have had 6 by injection with 8 more to go. Since starting the injections i have lost weight, about half a stone. (I lost half a stone previously during chemo). Initially i thought this was lack of appetite, but i am eating as much as i used to and still drop up to a pound each time. This may not seem much, but i was not considered overweight to start with. Does anyone else have this problem and what did you do about it.
