amethys,
The trials showed that most of the problems with herceptin and heart issues developed on those patients who had A/C along with herceptin. That is no longer a practice. Yes, there is always a risk with any medication. Your dr. will track you as you get your treatments so that they are on top of your health.
Even women who have heart value problems have been on herceptin. (SanDiego is one gal on the site) who is doing just great.

Allow yourself time to adjust to the dx. It is shocking and painful when first dx. then add to it you are a young mother with a family. It is normal to feel overwhelmed and frightened.

The updated information on Her2 is much better than a few years ago. You had 0 nodes, which is favorable.
Try to eat healthy, get some rest (easier said than done with three young kids). Do you have family or friends that support you and offer some help. Did you know there is an organization that will come and clean your house while you are having treatment? That could be a big help for you.

Yes, the treatment is worth it as you have many years ahead of you to enjoy your children and family.

Best Wishes,
Jean
