Did you know that March 3 is Triple Negative Breast Cancer Day?

 By Pat Battaglia

What IS Triple Negative Breast cancer (TNBC), anyway?

In TNBC, the cancer cells do not have three common factors that often guide treatment decisions. They don’t have too many estrogen receptors or progesterone receptors, and they don’t make too much of a protein called HER2. TNBC accounts for about 10% of all female breast cancer cases in the United States.

In honor of this day, and of all who are diagnosed with TNBC, we present three common myths and facts about this form of breast cancer.

Myth 1: TNBC is a single subtype of breast cancer.

Truth: The term “TNBC” describes only the absence of certain key features commonly found in breast cancer. However, research has revealed diverse biologic subsets within the TNBC classification, some of which can be targeted with specific treatments. Remarkable progress has been made in this field in recent years. And the work continues.

Myth 2: Only Black women get TNBC.

Truth: TNBC affects people of all races, ethnicities, and genders. However, it is also true that Black American women who develop breast cancer have an estimated 20 to 40 percent chance of receiving a TNBC diagnosis. At the present time, this disparity is poorly understood. Also at higher risk for TNBC are those under 40, as well as carriers of certain genetic mutations.

Myth 3: TNBC is the worst kind of breast cancer.

Truth: There is no “good” type of breast cancer. While TNBC is often considered to be more aggressive than hormone-positive breast cancer, each type carries unique challenges and opportunities for treatment. With over 30 years of clinical trials testing chemotherapies and novel, targeted therapies, the picture is changing for TNBC. It helps for those diagnosed with TNBC to talk with their oncology providers about the specific treatment options available to them. For some, enrolling in a clinical trial can be a positive step.
