Shannen Doherty's breast cancer in remission after 2-year battle

Shannen Doherty is in remission following a two-year battle with breast cancer, she announced Friday on her Instagram and Facebook accounts.

The former "90210" and "Charmed" actress, 46, made the announcement by posting a photo of herself with the caption, "Moments. They happen. Today was and is a moment. What does remission mean? I heard that word and have no idea how to react. Good news? YES. Overwhelming. YES."

However, this star knows that she isn't out of the woods yet, she said that she's well aware of the battle that lies ahead.

So, what's next for Doherty?

"In the meantime, decisions. Reconstruction which is several surgeries. Decision on taking a pill for the next five years that comes with its own set of problems and side effects. But for now.... remission. I'm going to just breathe. #cancerslayer."

Doherty was diagnosed with breast cancer in March 2015 and has been chronicling her battle against the disease on her Instagram page, ABC News reports.
