family history of uterine sarcoma anyone?

weety

Hi, I'm trying to research and find out what's going on with my family history.  There is lots of colon cancer and prostate cancer, but since these are so common, I'm focusing on the rare cancer my mom died of: uterine sarcoma.  This is a different cancer than the typical uterine (endometrial) cancer that we usually hear about.  Uterine sarcoma is extremely rare (I think it's 1 in 30,000 or something like that) and I'm just curious if this could be something related to the fact that I am getting premenopausal breast cancer at age 38.  My genetics counselor told me that often with genetic based cancers, it's the rare cancers that end up telling the whole story.  So . . . she's got me researching and trying to find answers since my BRCA 1/2 tests both were negative.
