Speaking to
People Magazine about the diagnosis, the actress said: "Although I don't have the easiest case scenario (...) I never had a moment where I was like 'Oh, am I going to die from this?' That was never really a thought. I think this entire time it's been more of like, 'OK, we're going to treat this and solve it.'"
As well as chemotherapy, Miranda McKeon has begun the process of freezing her eggs, but added that she may still be able to have children "naturally" later in life.
She told the magazine that she decided to have her eggs frozen as a "safety net".
She said: "I'll probably be able to have kids naturally on my own, and hopefully they'll just be donated to science in however many years, but we'll see."
As she undergoes cancer treatment, Miranda said that she is trying to be optimistic.
"I'm making my job to find the beauty in all of this," she told the publication. "I wouldn't have chosen this, I didn't choose this. I don't think anyone would choose this. But I'm making it my job to try and pull something out of this."
