The Courageous Health Journey: Breast Cancer and Advocacy

The most impactful news shared by Olivia Munn in 2024 was her private battle with breast cancer. In March 2024, she revealed she had been diagnosed in 2023, a diagnosis she chose to keep private for a year while undergoing intensive treatment.

The Luminal B Diagnosis and Proactive Testing

Munn’s diagnosis was a result of proactive medical intervention rather than finding a lump herself. Her doctor recommended a breast cancer risk assessment score, which unexpectedly placed her at a high lifetime risk of 37%. This score, combined with a subsequent MRI and biopsy, led to the diagnosis of Luminal B cancer in both breasts, an aggressive, fast-moving form. This event has turned her into a fervent advocate, urging other women to request the free, simple risk assessment test, emphasizing that it saved her life.

Multiple Surgeries and a Double Mastectomy

Following the diagnosis, Munn underwent a double mastectomy and a total of four surgeries over a ten-month period. Her openness about the physical and emotional toll of the procedures—including breast reconstruction—has provided a raw and honest look at the realities of cancer treatment. The revelation was made public in an open letter on Instagram, where she shared photos from her hospital stay, demonstrating her commitment to raising awareness. Adding a further layer of personal resonance, Munn also shared in 2024 that her own mother was diagnosed with breast cancer, highlighting the genetic and familial aspects of the disease.

A Year of Milestones: Secret Wedding, New Baby, and Career Comeback

While privately managing her health crisis, Olivia Munn also experienced profound joy and growth in her personal and professional life throughout 2024, culminating in two major family announcements and a significant return to acting.

Secret Marriage to John Mulaney

After a high-profile relationship, Munn and comedian John Mulaney surprised fans by secretly tying the knot. They were confirmed to have married over the Fourth of July weekend in 2024. The couple, who share a son, kept the wedding details private, reflecting a desire for intimacy and focus on their family unit amidst a challenging year. Mulaney, who had to deliver the news of her cancer diagnosis, has been a pillar of support throughout her health journey.

Welcoming Daughter Méi June Mulaney

The family grew again in 2024 with the arrival of their second child, a daughter named Méi June Mulaney, born on September 14, 2024. The couple utilized a gestational surrogate for the birth, a detail Munn shared to normalize and destigmatize the various paths to parenthood. Méi June's birth, which occurred in the Chinese Year of the Dragon, adds a beautiful cultural touch, honoring Munn's heritage. She joins her older brother, Malcolm Hiệp Mulaney, who was born in November 2021.

The Return to the Screen: Your Friends & Neighbors
