Probably breast cancer gets so much attention because it IS mostly a woman's issue...and historically women's issues get far less attention than men's issues.
This is why I made the Viagra crack. We've all heard of insurance companies that will pay for Viagra but not birth control.
My dad, at risk for colon cancer, was told at his last colonoscopy he could start coming in every 3 years instead of every year. My comment to my mom was "bullcrap...so at the end of year 2 something develops but we don't see it until a year later when it's too late?"
Breast cancer may be an issue we, um, hang our hat on...but that is an inroad to pave the way for, perhaps, research in ovarian cancer which is widely ignored.
Men notice our breasts, so it's a good issue to start with. They don't give a hang about our ovaries.
