Could Constant Clear Vaginal Discharge Post Uterine Ablation Be Due To Cancer?

I am 60 years old. About 7 years ago, I had an uterine ablation. About a week ago, I started having vaginal discharge 24/7. It is primarily clear, with some yellow tint. Some oder, but not much. I also have Mom, Dad, & sister who passed away with cancer. Is there a way to test the discharge? Should I see my primary care physician? Thanks
