Anyone aged over 18 who has at least one Jewish grandparent is eligible for testing. If you meet this criteria you can order a test here: https://jewishbrca.org/
Article TL;DR:
The tests check for faulty BRCA genes. People with Jewish ancestry are far more likely to have inherited faulty BRCA genes than the general population. There is a 50% chance of someone who has a faulty BRCA gene passing it on to any children.
Those born with impaired BRCA1 and BRCA2 genes have a greater risk of developing breast, ovarian, prostate or pancreatic cancer.
The NHS England screening programme is part of a drive to detect cancer early. Tests can be ordered online and completed at home, by taking a sample of saliva and sending it off to a laboratory.
