(OVCARE) cancer prevention strategy.
• In September 2011, the The Society of Gynecologic Oncology of
Canada (GOC) endorsed OVCARE’s cancer prevention strategy
by issuing a statement recommending that “physicians discuss
the risks and benefits of bilateral salpingectomy with patients
undergoing hysterectomy or requesting permanent, irreversible
contraception,” and that an “ovarian cancer prevention
(research) study focused on fallopian tube removal is a GOC
priority.” www.g-o-c.org
