here we go again

Hi, I am new to this site. After a 4 1/2 year remission from stage IIIa serous cancer,my CA125  went up only a little bit to 46, CT scan was clear but a PET scan showed a 4cm tumor in the presacral region plus some small ones on the lungs. After being given totally conflicting advice from the oncology team from: "Your tumor count is so low tou don't need chemo" "It's in your spine,why do you have an appointment with your cancer gynecologist? " "You'll need chemo definitely " Saw the cancer gynecologist who said it's not in the spine but on the bowel and first surgery,  followed by radiation therapy and than chemo. Anyone been through this and can tell me what to expect from bowel surgery? I've been told the surgery will be hard and hospital stay longer than last time. I would love to hear from you who have been in this place Looking forward to hearing from you Cori
