Hi.
My mom had a full hysterectomy 9 years ago and still had Ovarian Cancer which we just found out last year even her Ovaries are not there anymore.
I mean even if you will have a full hysterectomy, there is no guarantee that you will never have Ovarian Cancer or any type of cancer like fallopian ,stomach, etc. There is no assurance.
Like my mom's case until now, they don't know where her cancer started... but they just told us that more or less its Ovarian Cancer because of the CA125 level marker which is in the Female reproductive system.
I hope my mom's experience help you somehow.
God bless and take care.
