Hi @pfitzp
If you want to pay out of pocket for genetic testing, my breast oncologist advised using

for my son to have testing due to my BRCA2 mutation. He did their testing 5 years ago and has both the BRCA2 and CHEK2 mutations I have. I did the testing with him since they tested for mutations I hadn't been tested for. That is how I found out I also have the CHEK2 mutation. They also test for enzymes needed to metabolize meds and other stuff.

It's just a saliva test. They send you the kit and you send it back with your saliva. Easy.

Color's Hereditary Cancer Test analyzes 30 genes relevant for mutations that can increase your patient's risk for common hereditary cancers, including breast, colorectal, melanoma, ovarian, and other cancers.

It's currently $250 US plus shipping and handling. The results could let you know if you need to do more or could give you peace of mind if you don't have any of the cancer mutations. They'll send you your results and review them with you. One of their doctors can order the test for you if you check that box when ordering.

I agree with @windyshores about checking into anti-estrogen meds. That can reduce your chance of recurrence by 50%. Best of luck to you.
