Hi, just had results of CA125 test at 79, I have had pelvic and trans vaginal ultrasound , okay apart from a 3cm cyst on ovary , which has increased from 2.5 cm since 2011.

What does a result of 79 mean, my GP says it is very low risk, has anyone else knowledge of this type of score, 

i am also experiencing left side pain too but now awaiting another referral to a Colo-Rectal Consultant, could any problems other than gynae raise the CA 125 level?
