Another possibility herceptin may not help.

Hi Paul !
Thanks for your detailed post that I certainly treasure it for my self.
Can a BC patient, after a long period of time, develop a primary cancer in another organ from a prolong treatments, like tamoxifen & endless xrays?
Some oncologists may guess, say 95%, this as a scondary to the original BC as the biopsies happend to be more difficult to make and treat with herceptin+chemo drug as for BC. In this case if the tumor happend to be primary the treatment is of no help, i.e. 5% failed.
Thanks
