Joanna Kerns is opening up for the first time about being diagnosed with breast cancer.

The 64-year-old Growing Pains star reveals in a new interview with People that she underwent a double mastectomy at the end of 2016.

In November, after a routine checkup, Kerns was diagnosed with ductal carcinoma in situ, a non-invasive, stage zero cancer trapped inside the milk ducts. She decided to have the surgery a month later, "instead of risking radiation and the chance of it coming back."

The actress was shocked when she found out about her diagnosis because "breast cancer does not run in my family."

While she was going through this emotional process, one week after her mastectomy, her former Growing Pains co-star and on-screen husband, Alan Thicke, died from a heart attack.

“It was so devastating,” Kerns expresses. “It was just a very, very hard time. I did go to the memorial four weeks out, and I was very happy to see my whole cast and my producers and dear friends.”

The cast and many other celebs paid tribute to the actor upon finding out the devastating news. See how they honored Thicke in the video below.
