I'm adding this here for traffic - lots of people may not be aware that if they have/had one Jewish grandparent (doesn't matter whether they were Ashkenazi, Sephardi, Mizrahi, anything), they are eligible - both male and female - for testing to find out whether they have mutations in the BRCA genes that are associated with higher rates of particular cancers.
Whilst somebody who is Jewish or already knows there is a family history may be aware and have been able to access genetic testing referral, this scheme has now been widened to make it a simple online request to anybody, no referral required.
It's a simple saliva test and completely free. The only particular requirement is that the sample can't be dropped into a postbox, it has to go via the Post Office.
