Olivia Munn has undergone a ‘full hysterectomy’ in her ongoing battle with Cancer, just two months after her double mastectomy was revealed.

The actress said she underwent the fifth operation in her battle against Breast cancer last month in an effort to see more of her two-year-old son’s childhood.

‘I’ve now had a full hysterectomy. I had my uterus, fallopian tubes and ovaries removed,” Munn, 43, told Vogue in a Mother’s Day profile.

‘Performing a complete hysterectomy was a big decision, but for me the best decision because I had to be there for my family.’

The Newsroom star, who is married to comedian John Mulaney, said she made the decision after being given the choice between a hysterectomy and taking anti-hormone drugs that would have left her bedridden.

“I really had a moment of panic,” she said.

‘A real breakdown. Because it’s so strange when you’ve been with this body all your life, you’ve had your period for so long, you feel when you’re ovulating and suddenly it’s gone.’

She was diagnosed in April last year, just two months after she and her sister Sara tested negative following a genetic analysis that checks for 90 genes linked to cancer.

We called each other and high-fived over the phone. That same winter I also had a negative mammogram,” she revealed in March this year.

“Two months later I was diagnosed with breast cancer,” she revealed.

‘The biopsy showed that I had Luminal B cancer in both breasts. Luminal B is an aggressive, fast-moving cancer.

‘Thirty days after that biopsy, I had a double mastectomy. From one day I felt completely fine, until the next day I woke up in a hospital bed after a ten-hour operation.’

“Over the past 10 months, I’ve had four surgeries, spent so many days in bed I can’t even count, and learned more about cancer, cancer treatment, and hormones than I ever could have imagined.”

She and Mulaney, 41, managed to create two ‘healthy embryos’ after her latest egg retrieval, although the hysterectomy means she can no longer have children.

‘It’s interesting because my 33-year-old eggs were great. My 39 year old eggs? None of them worked,” she said.

‘As you get older, one month may have great eggs, the next month not so much. Obviously the month we did at age 39 was not a good month.

‘After my diagnosis we decided to try another round of egg retrieval and hoped it was a good month. “John and I have talked about it a lot and we don’t feel like we’re done growing our family yet, but we didn’t know whether I should have chemotherapy or radiation.”

The former Daily Show correspondent was only on her feet for a few weeks after her latest surgery before spraining her ankle, she revealed on Instagram last week.

She shared a short video of her in light blue shorts and a matching shirt, with a black brace on her left ankle.

The video – set to the theme Curb Your Enthusiasm – shows her zooming in on her ankle, first teasing that she suffered the injury in a much more serious manner.

‘I sprained my ankle today jumping out of a plane. And by plane I mean I tripped in a CVS parking lot,” she told her followers.

Munn, who shares son Malcolm, 2, with Mulaney, said she worried about the impact her illness would have on her family.

“Friends tried to cheer me up by saying, ‘Malcolm won’t remember this. Don’t worry,” she said.

“But I kept thinking to myself, ‘I’m going to remember this, that I missed all this stuff.’

“It’s his childhood, but it’s my motherhood, and I don’t want to miss any of these parts if I don’t have to.”
