Last December, I was diagnosed with Stage 1 Triple Positive Breast Cancer.

After completing surgery, chemotherapy and radiation I am now cancer free.

A big thank you to Angela Kinseys husband Josh Snyder for taking this photo.

Its just one example of the care they showed me during this journey.

Thank you for sharing and for inspiring.

After her doctor ordered a breast ultrasound, they found something in my left breast.

Im happy to say that I was recently re-screened, and the treatments worked, Fischer said.

I am cancer free.

I will continue to be treated and monitored to help my stay that way.
