Congratulations on the good news! Some years ago when I was being evaluated for an upcoming hysterectomy (fibroids, not cancer, fortunately) they spotted what looked like an ovarian cyst on the scan. Since I was already in my 50s, they said it was best to have ovaries out as well as uterus. When they operated -- lo and behold, no cyst. If you are not totally past menopause, apparently some things that look like cysts on scans are just normal monthly swelling of egg follicles (some are larger than others) and they don't show up on repeat scans. And, my sister-in-law when she was in her ate 30's had what looked like a cyst but was in fact found to be just extra tissue from her having endometriosis.
Small TA Grade 1, May-06; recur (2 tiny), same, June-08; TURBTs both times. BCG begun July-08, dosage to 1/3rd May-10, completed treatment December-11. All clear since 2008.
