I agree! Show your friend a copy of these posts (from women well versed in dealing with treatment decisions and changing Onc.). She MUST get a second opinion QUICKLY!
To find a doctor for second opinion, Go to
http://www.clinicaltrials.gov and type breast, HER2+++ and the state that you live in, in the search area.
Then look over several trials, doesn't matter which, but go directly to the bottom of each selected and look at Doctor names and Hospitals to get ideas on where to go for a second opinion/ Onc.
Perhaps your friend doesn't want to face this "head ON" sometimes we all want to just "wish" it away. But, treatment is DO-ABLE and it's her LIFE that's at stake!
Tell her run, don't walk to the next onc. She CAN do it!
