What is Triple Negative Breast Cancer?
In this section, we will delve deeper into what triple negative breast cancer is and how it differs from other types of breast cancer. Readers will learn about the characteristics and behavior of triple negative breast cancer cells and why it is called “triple negative.”
Characteristics of Triple Negative Breast Cancer Cells
Triple negative breast cancer is a subtype of breast cancer that lacks three receptors commonly found in other forms of the disease: estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). This means that triple negative breast cancer cells do not have receptors that can be targeted by hormone therapy or HER2-targeted therapy.
Triple negative breast cancer is typically more aggressive and has a higher risk of recurrence compared to other types of breast cancer. It affects a specific group of individuals and tends to occur more frequently in younger women, African American women, and individuals with BRCA1 gene mutations.
Why is it Called “Triple Negative”?
The term “triple negative” refers to the absence of three receptors: estrogen, progesterone, and HER2. In other words, triple negative breast cancer cells do not test positive for these receptors when examined through laboratory testing.
This classification is crucial for determining treatment options, as hormone receptor-positive breast cancers can be treated with hormone therapies that target the estrogen and progesterone receptors. HER2-positive breast cancers can be treated with targeted therapies that specifically block the HER2 receptor. However, since triple negative breast cancer cells lack these receptors, treatment options are more limited.
A better understanding of the molecular characteristics of triple negative breast cancer is leading to the development of targeted therapies and personalized treatment approaches. Ongoing research and clinical trials are focusing on identifying biomarkers and genetic abnormalities that can guide treatment decisions and improve outcomes for individuals with triple negative breast cancer.
