Actress Olivia Munn has shared that she was diagnosed with luminal B breast cancer in April 2023 and has since undergone surgical removal of both of her breasts.
“[Munn’s OBYGYN] looked at factors like my age, familial breast cancer history, and the fact that I had my first child after the age of 30. She discovered my lifetime risk was at 37 percent,” Munn wrote in an
What is luminal B breast cancer?
In order to find the most effective way to treat cancer, it’s now common for doctors to analyze the DNA of cancer cells. This gives an idea as to the kind of characteristics the cancer has and thus, what to use to target it. Based on this analysis, breast cancers can be split into
The type of breast cancer that Munn was diagnosed with,
You might hear of this cancer as hormone receptor positive (for either or both estrogen and progesterone) and with high levels of Ki-67. Luminal B cancers can also be positive for HER2, a protein receptor involved in cell proliferation.
How common is it?
The
Who’s at risk?
Though there aren’t any factors that put a person at risk of developing luminal B breast cancer specifically, there are some factors that contribute to an increased risk of breast cancer in general. These

What are the signs and symptoms?
The signs and symptoms of luminal B breast cancer can be the same as breast cancer in general. Some of the symptoms
Changes in skin texture, e.g. puckering/dimplingSwelling in your armpit or around your collarboneLumps and thickeningNipple dischargeA sudden, unusual change in size or shapeNipple inversion and changes in directionA rash or crusting of the nipple or surrounding areaConstant, unusual pain in your breast or armpit
Can it be treated?
Treatment for luminal B breast cancer might depend on a number of factors, taking into account elements like the proteins that characterize this subtype, how far the cancer has spread, your age, and your health. Together, this is what’s known as personalized medicine, which is becoming an increasingly common approach in cancer prevention, diagnosis, and treatment.
Luminal B breast cancer can often be treated with chemotherapy, but might also involve hormone therapy, treatments that target HER2, or surgery. In Munn’s case, she opted for a double mastectomy – surgical removal of both breasts.
What’s the prognosis like?
Though the survival rate of luminal B cancer can depend on whether it has spread or not, out of the four breast cancer subtypes, it has the second-highest five-year survival rate, sitting at 90.7 percent.
