Is your cousin on the maternal side? I have been reading about a type of her2+ breast cancer which may be X-linked--inherited from mother to daughter on the X-chromosome and related to FoxP3 a gene necessary for the function of T-regulatory cells of the immune system. These familial cases seem to be of ER+her2+ breast cancer will be hard to identify as her2 status has only begun to be tested relatively recently.

Are there any other females on your mother's side with breast cancer?

Sorry to pry, but within this information may lie some answers as to how ER+her2+ breast cancer arises and how it best is treated.

Thanks for any info!
