March 14, 2024—Actress Olivia Munn’s candid disclosures on Instagram about her aggressive breast most cancers — a shock discovery after a “clear” mammogram and destructive genetic exams — had been a poignant mixture of particulars about her most cancers journey and a cautionary story for girls.
Munn earlier this week revealed her 10-month battle with breast most cancers, which resulted in 4 surgical procedures and a double mastectomy, and used the social media website as a means of encouraging ladies to teach themselves concerning the illness and the significance of applicable screening exams.
Munn’s expertise reveals some truths that girls could not know: Most girls who get breast most cancers don’t have a genetic predisposition. Mammograms don’t detect all cancers. A person threat evaluation — which Munn’s OB/GYN physician really useful — can level to the necessity for extra testing to seek out tumors mammograms have missed.
Munn, 43, recognized for her work on The Every day Present with Jon Stewart, as economist Sloan Sabbith on the HBO political drama The Newsroom, and flicks together with Magic Mike, wrote intimately on Instagram about discovering out she had an aggressive type of most cancers generally known as luminal B regardless of having a traditional mammogram and testing destructive on a genetic check that she mentioned checked for 90 totally different most cancers genes.
Her physician did a person threat evaluation, discovering Munn’s lifetime threat was 37%, thought-about very excessive, and referred her to extra in depth testing, which detected most cancers in each breasts.
Munn mentioned in a sequence of Instagram posts that she initially saved her prognosis personal, explaining, “I wanted to catch my breath and get via a number of the hardest elements earlier than sharing.” She lauds her OB/GYN, Thais Aliabadi, MD, who determined to calculate the chance rating. “The truth that she did saved my life,” Munn wrote.
Munn’s preventing spirit and optimistic angle are obvious. “I’m fortunate,” she posted. “We caught it with sufficient time that I had choices.” She praised the efforts of John Mulaney, her associate with whom she shares a 2-year-old son. He researched therapies and medicine and posted photos bedside of their son.
Munn thanked her docs and different employees at Cedars-Sinai Medical Middle in Los Angeles and Windfall Saint John’s Well being Middle in Santa Monica, together with her surgical oncologist, Armando Giuliano, MD, her reconstructive surgeon, Jay Orringer, MD, her oncologist, Monica Mita, MD, and Aliabadi.
A spokeswoman for Munn mentioned the actress is just not doing interviews at the moment. Spokespersons at Cedars-Sinai declined to touch upon Munn’s case.
Genetics and Breast Most cancers
“Most individuals who get breast most cancers don’t have an inherited genetic mutation,” mentioned Nathalie Johnson, MD, medical director of the Legacy Well being Methods Most cancers Institute and the Legacy Breast Well being Facilities in Portland, OR, who was not concerned in Munn’s therapy.
“Solely 5 to 10% of people that get breast most cancers have a gene that exams optimistic,” agreed Joanne Mortimer, MD, director of Ladies’s Cancers Program and a medical oncologist at Metropolis of Hope in Duarte, CA. Mortimer was additionally not concerned in Munn’s care and spoke usually about breast most cancers therapy in circumstances just like Munn’s.
Most cancers Subtypes
Luminal breast cancers are these originating inthe luminal or inside lining of the mammary ducts. Each luminal A and luminal B want estrogen to develop, Johnson mentioned. Luminal A has a greater prognosis and is less complicated to deal with. Luminal B has a worse prognosis, she mentioned, and it’s typically dubbed B for “dangerous.”
Luminal B “requires chemotherapy and if it recurs; it’s simply more durable. It stops responding to endocrine remedy or estrogen-blocking medicine and so we have now to make use of different therapies.”
Genomic testing helps docs determine if the luminal tumors are A or B varieties, she mentioned. The prognosis for luminal B cancers can nonetheless be good, Johnson mentioned.
Past Mammograms
“Mammograms aren’t excellent,” Johnson mentioned. The screening can particularly miss cancers in breasts with dense tissue as a result of the cancers don’t present up as nicely on the imaging.
Density refers back to the quantity of fibrous and glandular tissues within the breast in comparison with fatty tissue. About half of girls age 40 and above have dense breasts, in keeping with the CDC. The mammogram report could embody details about whether or not breast density is excessive or low.
If breasts are dense, an ultrasound or breast MRI can be good supplementary exams, Johnson mentioned.
Although mammograms miss some cancers, Johnson urges ladies to endure the exams as really useful. The U.S. Preventive Providers Process Pressure, in its draft advice, requires mammograms starting at age 40 and repeated each different yr.
Even when mammogram outcomes present no proof of most cancers, if a lady feels one thing uncommon in her breasts, it’s time to return to the physician and ask about additional testing, Johnson mentioned.
An MRI is usually executed in ladies as younger as Munn, Mortimer mentioned, if they’re recognized to have dense breasts or a household historical past, each recognized to boost breast most cancers threat. “In somebody with a household historical past, we alternate MRIs with mammograms to extend the probabilities of detection,” she mentioned.
Particular person Assessments
In her Instagram posts, Munn praises her OB/GYN for suggesting a person threat evaluation. “Dr. [Thais] Aliabadi checked out components like my age, familial breast most cancers historical past, and the truth that I had my first baby after the age of 30,” Munn wrote on Instagram. “She found my lifetime threat was at 37%.”
That rating prompted the physician to refer Munn for an MRI after which an ultrasound and biopsy. “The biopsy confirmed I had Luminal B most cancers in each breasts,” Munn wrote. “Luminal B is an aggressive, fast-moving most cancers.” Thirty days later, Munn had a double mastectomy.
One such threat evaluation is on the Nationwide Most cancers Institute website. It takes into consideration a historical past of breast most cancers, earlier radiation to the chest, genetic mutations, age, race, ethnicity, historical past of a breast biopsy with a benign prognosis, age at first menstrual interval, age when first baby was born (over 30 raises threat), and first-degree relations (your dad and mom, sibling, or baby) with breast most cancers.
From that, it predicts a 5-year threat and a lifetime threat of growing breast most cancers, evaluating the affected person’s threat with the common threat of the inhabitants.
As an illustration, a 43-year-old White girl with no historical past of breast most cancers or earlier radiation, no genetic mutations, no earlier breast biopsies, first interval at age 12, 30 or older at first childbirth, and no first-degree relations with breast most cancers has a 13.2% lifetime threat of breast most cancers, barely above the common threat of 12.1%.
Therapy Choices
Moreover the kind of tumor detected, components equivalent to lymph node involvement drive therapy choices, Johnson and Mortimer mentioned.
For a younger girl with luminal B breast most cancers, the standard routine can be surgical procedure, chemotherapy, and estrogen-blocking remedy. “The luminal B prognosis remains to be good in the event you do the chemo in addition to the endocrine remedy.” Johnson mentioned.
Fashions can assess survival charges if the therapy contains chemotherapy or doesn’t, Johnson mentioned, serving to ladies to make their very own choices.
Mortimer known as Munn’s OB/GYN “fairly superb” to counsel the chance calculator and take motion, discovering the tumor a lot sooner than the subsequent scheduled mammogram would have.
