Comprehensive Guide to Triple Negative Breast Cancer (TNBC): Symptoms, Causes & Treatment Options

By Dr. Garvit Chitkara in Nanavati Max Institute of Cancer Care

Aug 22 , 2024 | 4 min read

Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer that poses unique challenges due to the absence of three common receptors—oestrogen, progesterone, and HER2—commonly targeted by therapies. Despite its aggressive nature, advancements in diagnostics and treatment options offer hope for better outcomes.

Triple Negative Breast Cancer Symptoms

Recognizing symptoms early is crucial for effective treatment. Common symptoms of TNBC include:

A lump or mass in the breast, often distinct from surrounding tissue.
Changes in breast size or shape.
Redness or pitted skin over the breast, resembling an orange peel.
Inverted nipple or unusual nipple discharge.
Swelling in the armpit or breast.
Persistent pain in the breast or nipple.

Early detection can significantly improve outcomes. Ensure regular screenings, especially if you fall within high-risk groups. Regular self-examinations and awareness of these signs can be life-saving.

Triple Negative Breast Cancer Causes

While the exact causes of TNBC remain unclear, research highlights several contributing factors:

Absence of Receptors: Unlike other breast cancers, TNBC lacks receptors for oestrogen, progesterone, and HER2, making it unresponsive to hormone and targeted therapies.
Genetic Mutations: BRCA1 and BRCA2 gene mutations significantly increase the risk of TNBC.
Ethnic and Age Factors: TNBC is more common in African-American and Hispanic women and tends to affect younger women under 50.

Nanavati Max offers advanced genetic testing and counseling to help assess your risk. Consult with our specialists today.

Stages of Triple Negative Breast Cancer

TNBC is classified into five main stages:

Stage 0: Non-invasive; abnormal cells confined to ducts or lobules.
Stage 1: Tumor up to 2 cm, with no spread to lymph nodes.
Stage 2: Tumor larger than 2 cm or spread to nearby lymph nodes.
Stage 3: Tumor spreads to chest wall, skin, or lymph nodes near the breastbone.
Stage 4: Metastatic cancer that spreads to organs like lungs, liver, or bones.

Understanding these stages helps guide treatment plans and prognosis. Early-stage TNBC often has higher survival rates, with Stage 0 exceeding 90%.

Diagnosis of Triple Negative Breast Cancer

Diagnosis involves a combination of techniques to confirm TNBC and plan treatment:

Biopsy: Tissue analysis to identify cancer subtype.
Imaging: Advanced imaging techniques like mammograms, MRIs, CT scans, and PET scans to evaluate tumor size and spread.
Genetic Testing: Assessing for BRCA mutations to determine personalized treatment options.

Prevention of Triple Negative Breast Cancer

Although TNBC cannot be entirely prevented, certain lifestyle and medical strategies can reduce the risk:

Maintain a healthy lifestyle: Regular exercise, balanced nutrition, and maintaining a healthy weight.
Limit alcohol consumption: Restrict intake to one drink per day or less.
Avoid smoking: Smoking is linked to an increased risk of several cancers, including breast cancer.
Schedule regular check-ups: Annual screenings can aid in early detection.
Consider genetic counseling: Individuals with a family history of breast cancer can benefit from genetic testing.

Triple Negative Breast Cancer Treatment Options

Effective TNBC treatment requires a combination of approaches tailored to the patient's stage and genetic profile. Common treatments include:

Surgery

Lumpectomy: Removes the tumor and surrounding tissue.
Mastectomy: Removes the entire breast tissue, often recommended for advanced stages.

Chemotherapy

Used pre-surgery (neoadjuvant) to shrink tumors or post-surgery (adjuvant) to destroy residual cancer cells.

Radiation Therapy

High-energy rays target and eliminate microscopic cancer cells post-surgery.

Advanced Therapies

PARP inhibitors: Effective for TNBC linked to BRCA mutations.
Immunotherapy: Activates the immune system to fight cancer cells.
Clinical Trials: Access to innovative and experimental treatments.

Side Effects of Triple Negative Breast Cancer Treatment

Common side effects of TNBC treatment include:

Hair loss and nausea (common with chemotherapy).
Fatigue (due to surgery and radiation).
Skin irritation or sensitivity (often caused by radiation therapy).

Coping Strategies:

Stay hydrated and maintain a balanced diet to manage fatigue.
Use prescribed medications for nausea and other side effects.
Consult cancer specialists for physical therapy or lifestyle adjustments to combat fatigue and lymphedema.

Frequently Asked Questions

1. What Factors Influence the Prognosis of TNBC?

The prognosis of TNBC depends on the stage at diagnosis, age, overall health, and tumor response to treatment.

Stage 0 survival rate: Over 90% with early detection.
Advanced stage survival rates: Vary based on treatment and other factors.

2. Is Triple Negative Breast Cancer Hereditary?

While not all TNBC cases are hereditary, BRCA1 and BRCA2 mutations significantly increase the risk. Genetic counseling is recommended for individuals with:
