Clear Cell Endometrial Carcinoma: Rare, aggressive, hard to treat

Hello, I'm new to this group but would like to find others with my type of cancer to chat with.
I was duagnosed in January with clear cell carcinoma endometrium. (I had uterine cancer previously but was lost to folliw up) I had surgery in February and had everything removed including lymph nodes. I was told they caught it early but to remember it is a metastatic cancer and can return anywhere in my body with no signs or symptoms. I was also told there is no test to detect recurrence.
I'm caught between feeling relieved and grateful and terrified it will hit me again out of the blue) Is there anyone out there who can relate?
