My daughter is only 21, she got her first tumor at the age of 14 (I hear that's fairly uncommon at that age for this rare type of tumor) she has since had 9 surgeries for 11 more of the same type of tumor (which I hear is also quite rare at any age). They have finally removed the ovary that all of the tumors were on along with her appendix during the same surgery. She also suffers from endometriosis. They have now implanted the Morena IUD to help slow down her endometriosis. My question is what is the likely hood of these tumors starting to grow on her other ovary and how likely are the to become borderline or malignant the more she gets?... A few of them have torsioned the ovary and she currently has a growth on her uterus. Should she insist that her GYN do a biopsy on the uterine growth considering her history?... Any answers are greatly appreciated!
