Your mom's oncologist should be able to get testing done. If she tests positive, you can be tested. Or, you can do your own genetic testing even if she does not get tested. There's the invitae test or even 23&me. Stay strong. You're not alone. God bless. 🙏
Highly recommend getting tested. I finished chemo in Jan for ovarian. Learned I was BRCA1+. My sisters, mom, nieces (so far) test positive. My mom and sisters are under going prophylactic ovary removal. My mom had hers in May and pathology found cancer. It was found early.
