does anyone with her2+ breast cancer have a mother who also has her2+ breast cancer?

I did a year of graduate work in medical genetics eons ago (around 1975, I think)

The articles on breast cancer genetics beyond BRCA1/2 are extremely technical and haven't really shown me any pattern to aid my understanding of the big picture.

This "snapshot" of the "little picture" from all of you piques my curiosity and I will search the literature to see if there is more on this.

I doubt it, as many of you commented, her2 testing is so new and not uniformly performed. Perhaps we can get some researcher interested...

Thanks again,
