Re: Monthly herceptin

I asked my onc exactly the same question. He very honestly answered that the 'theory' is that herceptin may drop off cancer cells at about 3 weeks so to regive at this time appeared sensible as it may then boost back the number of bc cells covered. He stressed that this is a best guess! As herceptin is still detectable at a month they don't feel the need to give a loading dose until after this period of time has lapsed.
