Signatera test at 2 years remission, worth doing?

A little history:
Aug 2022- Diagnosis of bilateral IDC breast cancer, HR+, HER2-, ki67 @ 19%, Grade 2 on left, Grade 1 on right.
Aug 2022- Bilateral lumpectomy and all armpit nodes removed, both sides. 1 left LN had cancer—Oncotype of left= 23, Oncotype of right = 11.
Sept 2022-Nov 2022- 4 rounds of T/C chemo.
Nov 2022- Started Letrozole
Nov 2022- Started monthly Lupron injections.
Nov 2022- CT with contrast- "NED"
Nov 2022- Cancer antigen test 43 (same day as last chemo infusion)
Dec 2022- Bilateral mastectomy with reconstruction (my choice on both), no cancer in any tissue.
Feb 2023-Apr 2023- 5 weeks of radiation on left= chest, breast, armpit, and neck.
May 2023- started bi-annual Zometa infusions to strengthen bones.
June 2023- Removal of both ovaries/tubes, stopped Lupron.
Oct 2023- Breast cellulitis, emergency surgery to remove implants
June 2024- Diep flap surgery
Tuesday, 6/3/25 - will be my 6-month labs, exam, and Zometa infusion. I asked for the Signatera blood test because waiting around for the other shoe to drop sucks. I like to know everything.
Note: I was 47 at the age of diagnosis. My mother, 68 at the time, was diagnosed with the same bc 3 weeks after me. Our genetic testing came back negative. In 2020, we both started getting testosterone pellets every 3 months. In 2023, my oncologist ordered the ingredients of the pellets. There was testosterone AND estradiol in them. My mom and I got the pellets at the same place. When I was first diagnosed by the breast specialist/ radiologist in August 2022, she asked me who my doctor was, and I mentioned the name of the doctor who gave me the pellets. The radiologist replied, "Oh yes, I know her, I have her on speed dial!" Very strange.

I would like to hear thoughts from anyone who has done the Signaterra test with a similar history to mine. I'm afraid that if it's positive, I will lose my mind.
