A cancer diagnosis, of any stage, is devastating news. Not only do you discover your body is turning against you, but you now have endless decisions to make about who to tell, what doctors to visit, what treatment is right for you—and so on and so on.

With metastatic breast cancer, or stage IV cancer, you're faced with the additional burden of knowing that your battle is an uphill one.

Metastatic breast cancer occurs when breast cancer cells spread from the original cancer site and grow in other areas of the body. This can happen months or even years after the original diagnosis.

While rhetoric around breast cancer (think pink ribbons) is prevalent, there are not a lot of open, honest conversations about the realities of metastatic breast cancer, leaving women to suffer alone.

"One in 3 women will live with stage IV metastatic cancer until they die," said Dana Donofree, founder and CEO of AnaOno, "and we don't talk about it because we're scared to talk about it."
