HELP!!! PET scan endometrial lighting up and doc siding with radical hysterectomy

I was diagnosed with Adenocarcinoma of cervix, an endometrioma, dermoid cyst, and potential endometriosis. I was hoping to be able to be eligible for the cone procedure so that I could preserve my fertility. I did a pet/ct scan and the doctor stated that while he does not see the cancer in my uterus, he feels as if a radical hysterectomy is the best option due to my endometrial lighting up on the scan.

I am very conflicted and heartbroken. The doctor wants to remove everything with the exception of my ovaries. His reasoning is he believes due to the endometrial lighting up, it could be starting to spread to my uterus;there would be a low chance the cone surgery would work and opting for the cone would push back my potential radical hysterectomy 6-7 weeks.

My partner and I planned on having children. We would not have money for a surrogate. Would it be silly to still considered trying the cone surgery due to the maybe chance it could work and I could keep all my lady parts or would it be too risky?
