Complex cysts can be benign, yes. But with a rising CA-125 and being age 50, I would not leave anything to chance. You should have the questionable cyst removed, sooner rather than later, by the gyn/onc.
Hi..i know how scary this can be... im going through it also. One good thing to think about is after 6 weeks your doctors said the cyst looks good..probably because they hadnt grown ...thats a great sign!! Ive heard the CA125 can go up and down for many reasons..infections can make them go up..even benign cysts can make them go up. Your in good hands too!
