Could some of this non-BRCA bc have an epigenetic basis?
I know that since my BRCA results came back (negative), there have been other genetic pieces of the puzzle ferreted out. Myriad stated on the results that as time went by if other types were identified, they would contact me....
Since I have one aunt who died of bc mets to the brain I wonder if hers was HER2 positive, but she died many decades ago. No one else in the family died of bc, and all lived fairly long lives or are still living without recurrence. Which, again, makes me wonder why risk is not considered in regard to the longevity/recurrence of those in the family who have had bc?
