Just months earlier in April, Munn had opened up to PEOPLE about her “terrifying"breast cancer diagnosisa year earlier, which resulted in four surgeries, a double mastectomy and medically induced menopause.

Back in May, Munn toldVoguethat after her diagnosis she froze her eggs to allow herself and Mulaney the opportunity in the futureto expand their family, after having previously frozen her eggs at ages 33 and 39.

Her Sept. 4 timeline also detailed that she underwent lupron treatment in November 2023, a partial hysterectomy/oophorectomy in April 2024 and, most recently, arimidex treatment in August 2024.

Throughout, Munn has remained focused on her son. When speaking to PEOPLE in April, she shared that being with Malcolm during the course of her treatment has given her deep joy.

“When I’m with him, it’s the only time my brain doesn’t think about being sick. I’m just so happy with him,” she said. “And it puts a lot of stuff into perspective. Because if my body changes, I’m still his mom. If I have hot flashes, I’m still his mom. If I lose my hair, I’m still his mom. That’s really what matters the most to me. I get to be here for him.”
