I Had Ovarian Cancer 4 Years Ago. I Will See

I had ovarian cancer 4 years ago. I will see my doctor once a year starting next year. I get tested for Ca125. I read that there is a CTC test. My question is, would this test be helpful for me. My ovarian cancer tumor ruptured and all the stuff was spilling into my abdomen for 4 days until I had a surgery. Although I had chemotherapy, I am concerned that I might have more cancer cells than a normal person would.
