@greatgrandma2025 These are all "liquid biopsies" which refers in this case to blood draws where the blood is then tested for specific

Some physicians order these tests for their patients and some do not. It depends on the type of cancer, and how aggressive the cancer is. The oncologist may order these tests to gauge the effectiveness of the treatment such as chemotherapy.

I was diagnosed with endometrial cancer - endometrioid adenocarcinoma, FIGO Grade 1 Stage 1a. My oncologist told me that this cancer was not aggressive and so this is why these blood tests were not indicated.

As you read through these websites please notice that each of these tests are for cancers in other parts of the body.

Have you asked your oncologist about whether any of these tests are indicated for you? If your oncologist says "no" you can then ask what is proposed in your case to scan for the potential of cancer in other places in your body. From what you shared it sounds like imaging scans such as CT is what your oncologist orders for you. Is that correct?

@greatgrandma2025
Are you saying your CA 125 test result was 2.8?
