A septed ovarian cyst, not a functional cyst And slightly enlaged uterus 10.5 CM, option of surgery or ultrasound In 6 wks, should I worry, cancer?

Depends. Septa come in thin and thick. If the septa are thin then that is good. The thicker they are the harder it is to tell if it is benign or not. The size of the uterus is not that bad. Talk to your doctor for more details before making a decision .
