I haven't been asked that, but mine sort of was preventative. The majority of my cancer was in my uterus. My ovaries & tubes were completely clean. My cancer metastisized to my omentus. My surgeon removed my uterus, tubes, ovaries & omentum. My surgeon is convinced he got all the cancer. We did the chemo just in case there are any cancer cells hanging around. It's still insensitive to ask, as the nurse should have access to your treatment plan.
