National Metastatic Breast Cancer Awareness Day: A Letter from Leslie

National Metastatic Breast Cancer Awareness Day

Today, October 13, 2025, is National Metastatic Breast Cancer Awareness Day. I am now almost eight years metastatic, and I am thriving.

Almost eight years ago, I was diagnosed with stage IV de novo breast cancer just two months after receiving an all-clear mammogram and ultrasound. I had no symptoms, no warning signs — it was the shock of my life. I quickly learned that breast cancer had been hiding in my dense breast tissue, invisible on a mammogram, for possibly a decade.

I Am Grateful

I am grateful to still be here. Grateful for every sunrise, every hug, every ordinary moment that adds up to an extraordinary life. I am grateful for the doctors, researchers, friends, and family who have supported me since my diagnosis. And I am deeply grateful for the opportunity to turn my experience into purpose through My Density Matters — helping women learn what I didn’t know soon enough.

I Am Hopeful

I am hopeful because I see progress. Awareness of dense breast tissue is growing. Conversations are happening in doctors’ offices that never used to happen. More women are learning to ask the right questions, to understand their own risk, and to take action. Hope thrives in knowledge, and it grows stronger every time a woman learns about her breast density and takes action accordingly.

But I Am Frustrated

I am frustrated because, despite progress, too many women are still dying from breast cancer that could have been found earlier. Too many are still diagnosed at later stages. Too many women (and doctors) still assume a “normal” mammogram means they are safe — when for women with dense breasts, that may not be true. Dense breast tissue can hide cancer and poses an increased risk, and yet so many women are still not being screened with available technologies beyond mammography when they should be. We know better — and we must do better.

A Personal Ask

From me to you — please, find out your breast density and talk with your doctor about your additional screening options. Use the tools and the knowledge now available to you, so my story doesn’t become your story.

The My Density Matters website can help you understand what to ask, what to do next, and how to take charge of your breast health.

Breast density hinders the early detection of breast cancer, and early detection saves lives.
Please, take action today!

With gratitude,
