Hi @Scarstef So very sorry to hear about your sister. I can't think of much worse than losing a child while also battling this disease. My heart goes out to her. And I take it you're who she leans on for support...that being the case, we are so grateful to our caregivers for being there for us..physically and emotionally. It's a huge burden to bear and so much appreciated.
As for the PARP, there are a few out there now. I can understand her obsession but maybe if she likens it to having something like diabetes. You're never cured but insulin allows you to live a longer and more fulfilling life. I am aware of women who have been on PARP for over 10 years now and still standing strong.
As @Flowergirl said, input PARP or Olaparib into the search function on this site. There have been many interesting discussions on the subject that you and your sister might find helpful. And please encourage her to reach out to us here directly. We'd love to hear from her and be there when she needs some inspiration.
