Dear Carol,
Your post is very heartwarming, I'm glad you are fighting and winning. You have all the "right stuff" to keep on for a long time, so as Lisa says the best thing to do right now is throw any and all predictions out the window! Your attitude will carry you far, and the Herceptin will help OF COURSE. When and if the cancer progresses again, you have many options in the way of chemos as Herceptin is very synergistic with some. Stay informed through this site, there's a wealth of info here, so take the time to check out all the links.
Is it springtime in Scotland right now?
