Triple Negative Breast Cancer (TNBC)
A Challenging Subtype
Triple Negative Breast Cancer (TNBC) is a subtype of breast cancer that lacks the three most common receptors found in breast cancer cells: estrogen receptors (ER), progesterone receptors (PR), and human epidermal growth factor receptor 2 (HER2). TNBC accounts for about 10-15% of all breast cancers and tends to be more aggressive, with a higher risk of recurrence and poorer prognosis compared to other breast cancer subtypes.
Characteristics of Triple Negative Breast Cancer TNBC has several distinct characteristics that set it apart from other breast cancer subtypes:
- Lack of ER, PR, and HER2 receptors, meaning it does not respond to hormone therapy or HER2-targeted therapies
- Tends to grow and spread more quickly than other types of breast cancer
- Often diagnosed at a younger age, particularly in women under 40
- More common in women with a BRCA1 gene mutation and women of African or Hispanic descent
- Higher risk of recurrence within the first 3-5 years after diagnosis
Symptoms of TNBC are similar to other types of breast cancer and may include a lump or mass in the breast, changes in breast size or shape, skin dimpling or irritation, and nipple changes or discharge.
Diagnosis and Treatment
Diagnosing TNBC involves a combination of imaging tests, such as mammography and ultrasound, and a biopsy to determine the tumor’s characteristics. If the biopsy confirms the absence of ER, PR, and HER2 receptors, a diagnosis of TNBC is made.
Treatment for TNBC typically involves a combination of therapies, including:
- Chemotherapy, which is the main systemic treatment for TNBC due to the lack of targeted therapies
- Surgery, such as lumpectomy or mastectomy, to remove the tumor and surrounding tissue
- Radiation therapy to reduce the risk of local recurrence after lumpectomy
Researchers are actively investigating new treatment options for TNBC, including immunotherapy, PARP inhibitors for patients with BRCA mutations, and other targeted therapies.

“I remember googling triple negative breast cancer and finding all these stories of women who had passed and I so badly want to be the girl you see who thrives. It took me a while to realize their story isn’t mine.”
Jena’s story reminds us of the importance of maintaining hope and resilience in the face of a challenging diagnosis. Her determination to thrive serves as an inspiration for others navigating the uncertainties of TNBC.
Coping with TNBC: Support and Self-Advocacy
Facing a diagnosis of Triple Negative Breast Cancer can be overwhelming, both emotionally and physically. To navigate this journey, it’s crucial for individuals to have access to comprehensive support services, including:
- Emotional support through counseling, support groups, and peer mentoring
- Genetic counseling and testing for those with a family history of breast cancer or a known BRCA mutation
- Palliative care to manage symptoms and improve quality of life during and after treatment
- Assistance with practical concerns, such as financial planning and work accommodations
Self-advocacy is also essential for those living with TNBC. This may involve seeking second opinions, staying informed about the latest research and treatment options, and communicating openly with healthcare providers about concerns and preferences.
