Understanding Luminal B Breast Cancer & Olivia Munn’s Journey
Breast cancer diagnoses are deeply personal, and understanding the specifics of each type is crucial for both patients and those supporting them. Recently, actress Olivia Munn bravely shared her diagnosis of Luminal B breast cancer, bringing increased attention to this specific form of the disease. This article will delve into what Luminal B cancer is, how it differs from other types, and provide an update on Olivia Munn’s current health and advocacy efforts.
What Defines Luminal B Breast Cancer?
Luminal B breast cancer is a subtype categorized by specific characteristics of the cancer cells. According to experts at City of Hope, it’s defined by the presence of estrogen or progesterone receptors (or both). However, unlike some other types, it doesn’t express the HER2 protein.
This distinction is vital. While luminal A and Luminal B cancers share hormone receptor positivity, Luminal B frequently enough exhibits a higher rate of cell proliferation. This means the cancer cells are dividing and growing more quickly, perhaps making it more aggressive than Luminal A. Specifically, the presence of HER2 expression in some Luminal B cases contributes to this faster growth. Consequently, Luminal B typically receives a higher grade and, historically, a less favorable prognosis than Luminal A.
Olivia Munn’s Diagnosis & Treatment
