You need to have a blood sample from a relative who has survived the disease to have the genetic testing. I was supposed to get it done as my mum had ovarian cancer and her mum had breast cancer, mum had already died but grandma was still alive- sadly because the wait for an appt was quite a few months Grandma died suddenly 3 days before the appt so i couldn't be tested. I wish I could have because grandma's mum died of cancer of the uterus in the 40s and i suspect it could've been the same kind of thing.

I would definitely get the testing done first.
