Inflammatory Breast Cancer

Overview: What Is Inflammatory Breast Cancer?

Inflammatory breast cancer (IBC) is a rare but aggressive type of breast cancer. Unlike most breast cancers that form a lump, inflammatory breast cancer often spreads quickly and causes the breast to look swollen, red, and inflamed. It accounts for only 1–5% of all breast cancer cases, but it tends to grow and spread faster than other types.

Because inflammatory breast cancer can progress rapidly, early detection and treatment are critical. Many women mistake its symptoms for an infection, which can delay diagnosis. Understanding the warning signs and seeking medical care promptly can make a big difference in outcomes.

What Are the Types of Inflammatory Breast Cancer?

Inflammatory breast cancer itself is a distinct form of breast cancer, but researchers classify it based on the kind of cells involved or specific molecular features:

• Invasive Ductal Carcinoma presenting as IBC: The most common type, starting in the milk ducts.
• Triple-Negative IBC: Cancer cells lack estrogen, progesterone, and HER2 receptors. This type is harder to treat because fewer targeted therapies are available.
• HER2-Positive IBC: Cancer cells have too much of the HER2 protein, making them aggressive but also responsive to HER2-targeted drugs.
• Hormone-Receptor Positive IBC: Cancer cells use estrogen or progesterone to grow, which means hormone-blocking treatments can help.

What Are the Causes of Inflammatory Breast Cancer?

The exact cause of inflammatory breast cancer is not fully understood. Like other cancers, it happens when genetic changes in breast cells cause uncontrolled growth. These abnormal cells block the lymph vessels in the breast skin, leading to swelling, redness, and the “inflamed” appearance.

Unlike other breast cancers, inflammatory breast cancer is less strongly linked to traditional risk factors like family history, though obesity and younger age have been noted as associations. While you cannot always prevent inflammatory breast cancer, knowing your risks and being alert to unusual breast changes can help with earlier detection.

What Are the Symptoms of Inflammatory Breast Cancer?

Inflammatory breast cancer often develops quickly, and its symptoms can appear in just a few weeks. Unlike other breast cancers, it usually does not form a lump.

It is important to watch out for:

• Redness over one-third or more of the breast.
• Swelling and heaviness of the breast.
• Skin changes: thickening, dimpling, or a “peau d’orange” (orange peel) texture.
• Pain or tenderness in the breast.
• Warmth over the affected area.
• Nipple changes: flattening, inversion, or discharge.
• Swollen lymph nodes under the arm or near the collarbone.

Because these signs can resemble an infection (mastitis), many women first receive antibiotics. If symptoms do not improve within a week, it’s important to see a breast specialist immediately.

How Is Inflammatory Breast Cancer Diagnosed?

Diagnosing inflammatory breast cancer requires a combination of tests.

• Physical Exam: A doctor checks for redness, swelling, and skin changes.
• Mammogram: X-ray images of the breast can detect suspicious growths.
• Breast Ultrasound: Helps distinguish between solid masses and fluid-filled cysts.
• Breast MRI: Provides detailed imaging, often used for high-risk patients.
• Biopsy: A small sample of tissue is taken and tested in the lab to confirm cancer. A core needle biopsy also helps doctors determine the cancer’s grade and whether it has hormone receptors (estrogen and progesterone) or HER2 protein, which guide treatment decisions.
• Skin punch biopsy: Often done to confirm cancer cells in dermal lymphatics, which supports the diagnosis of inflammatory breast cancer.

What Are the Treatment Options for Inflammatory Breast Cancer?

Because inflammatory breast cancer is aggressive, treatment is usually multimodal (using several approaches):

• Chemotherapy: With a goal to shrink the tumor before surgery, neoadjuvant chemotherapy is the first line of treatment for inflammatory breast cancer. Common drugs used are anthracyclines, taxanes, and platinum agents.
• Surgery: Due to the nature of inflammatory breast cancer, where cancer cells spread under the skin, a modified radical mastectomy (removal of the entire breast and nearby lymph nodes) is usually required to achieve clean surgical margins.
• Radiation Therapy: Given after surgery to target the remaining cancer cells in the chest wall and nearby lymph nodes.
• Targeted Therapy: For HER2-positive inflammatory breast cancer, treatment with drugs like trastuzumab (Herceptin) and pertuzumab is required. PARP inhibitors may be considered in patients with metastatic HER2-negative breast cancer and BRCA mutations, usually after standard chemotherapy and targeted therapy options.
• Hormone Therapy: If the cancer is hormone-receptor positive, medications like tamoxifen or aromatase inhibitors are used.

Proton Therapy: When Is It Applicable?

Available at Apollo Proton Cancer Centre, proton therapy uses protons instead of X-rays to deliver radiation more precisely to cancer cells. This allows doctors to target the tumor while minimizing damage to healthy surrounding tissue, including the heart and lungs.

Proton therapy may be considered for inflammatory breast cancer in the following situations:

• When the tumor is located close to critical organs such as the heart or lungs, especially in left-sided breast cancers with internal mammary node involvement.
• In younger patients, to reduce long-term side effects from radiation exposure.
• For patients who have already received radiation to the chest and require additional treatment.
• In complex cases where precision is essential to reduce radiation-related complications.

While proton therapy is not required for all patients with inflammatory breast cancer, it can be especially beneficial in selected cases where traditional radiation may pose higher risks.

Screening and Prevention of Inflammatory Breast Cancer

Unlike other breast cancers, inflammatory breast cancer often cannot be detected through routine mammograms because it may not form a lump. Common screening and prevention include:

• Breast Self-exams: Regular breast self-examinations are encouraged as they can help detect changes in the breast.
• Genetic testing and counselling: High-risk women, including those with a strong family history of cancer, may consider BRCA testing.
• Lifestyle changes: Maintain a healthy optimal weight, exercise regularly, avoid alcohol and smoking.
