Olivia captioned thepost: I was diagnosed with breast cancer.
Olivia continued: My sister Sara had just tested negative as well.
That same winter I also had a normal mammogram.

I guess I havent felt like there was time to cry.
My focus narrowed and I tabled any emotions that I felt would interfere with my ability to stay clearheaded.

We caught it with enough time I had options.
I want the same for any woman who might have to face this one day.
