Inflammatory Breast Cancer

What Is Inflammatory Breast Cancer?

Inflammatory breast cancer is an uncommon and invasive type of breast cancer that is often confused with everyday issues like a skin rash, infection, or an allergic reaction. It grows quickly and makes the breast look swollen and inflamed, which is why it is called inflammatory breast cancer.

Unlike other cancers, inflammatory breast cancer (IBC) does not form a lump. Instead, cancer cells block lymph vessels in the skin of the breast. When these vessels get blocked, the breast appears red, warm, painful, and swollen. These signs are similar to an infection, which makes it harder to recognize.

IBC is uncommon, making up only about one to five percent of all types of breast cancer. It tends to affect younger women, often under 40, and is more common in people who are overweight or obese.

Because it spreads quickly, getting immediate medical care is essential. Early recognition and timely inflammatory breast cancer treatment make a big difference.

Who Is Likely to Have Inflammatory Breast Cancer (IBC)?

Anyone can get inflammatory breast cancer, but some factors that increase the risk are:

1. IBC is more common in women than in men.

2. IBC affects younger individuals, and people under 40 are diagnosed frequently, though the median age of diagnosis is around 57.

3. Black people are at a higher risk of having IBC compared to white individuals.

4. Being overweight increases the risk of developing IBC compared to people with a normal BMI (body mass index).

What Are the Factors That Cause Inflammatory Breast Cancer?

The main cause of inflammatory breast cancer is still not known, but experts believe it develops due to a fusion of genetic and environmental changes. IBC is considered a form of invasive ductal carcinoma, meaning it starts in the milk ducts and then gradually spreads into the surrounding breast tissue.

In IBC, abnormal cells begin to grow uncontrollably because of changes in their DNA. These cancer cells typically originate in the ducts that carry milk to the nipple and then spread to the nearby healthy tissue. As the cancer spreads, it blocks the lymph vessels, tiny tubes that normally drain lymphatic fluid from the breast. When these vessels are blocked, fluid builds up, causing the breast to become red, warm, swollen, and painful. This is what gives IBC its inflammatory appearance, even though it is not an infection.

Some factors that cause IBC are

• A family history of breast cancer.

• Being younger (especially under 40).

• Obesity or being overweight.

• Previous exposure to radiation or harmful chemicals.

• Having had another type of cancer.

What Are the Signs and Symptoms of Inflammatory Breast Cancer?

Inflammatory breast cancer is tricky to spot because it usually does not form a lump, unlike most other types of breast cancer. Instead, it causes rapid changes in the breast that are often mistaken for an infection or allergic reaction. Symptoms appear and worsen within weeks to a few months.

Common signs and symptoms of IBC are

• Redness or discoloration of the breast (red, purple, or pink areas), often covering at least one-third of the breast.

• Breast swelling, causing one breast to appear larger and heavier.

• Warmth, and the breast may feel hot to the touch.

• Pain, discomfort, or tenderness, sometimes felt near the armpit.

• Itching or a burning sensation.

• Thickened skin, ridges, or dimpling that looks like an orange peel.

• Firmness or tightness in the skin.

• Inverted or flattened nipple.

• Nipple discharge.

• Swollen lymph nodes in the armpit or near the collarbone.

How Is Inflammatory Breast Cancer Diagnosed and Staged?

Inflammatory breast cancer can be tough to diagnose because it does not form a lump. The diagnosis is based on breast changes and confirmed through tests.

This includes:

1. Physical Examination: The doctor examines the breast for signs of swelling, warmth, redness, nipple changes, or skin changes. Because early IBC resembles an infection or rash, it is often mistaken for a skin problem.

2. Imaging Tests: Scans like ultrasound and mammograms are used to examine the breast tissue in and around the breast to detect abnormalities or lymph nodes.

3. Biopsy: This is the most important test. A small piece of breast tissue is taken (sometimes under local anesthesia) and examined in a laboratory to confirm whether the abnormal mass has cancer cells in it or not.

Staging:

IBC is usually already advanced when diagnosed because it spreads quickly. It is almost always the following:”

Stage III - Cancer has spread to the skin or lymph nodes but not to other organs.

Stage IV - In this stage, the cancer has spread to other distant organs like the lungs, liver, or bones.

How Is Inflammatory Breast Cancer Treated?

Because IBC grows fast, treatment usually starts immediately and often involves a combination of therapies. Inflammatory breast cancer management involves:

1. Chemotherapy is given first to shrink the cancer. It can be taken orally or intravenously.

2. Surgery is done after chemotherapy to reduce cancer. Surgery is performed to remove the breast (mastectomy) along with affected lymph nodes.

3. Radiation therapy uses high-energy rays to destroy any cancer cells that are still present and reduce the chance of recurrence.

4. Targeted or hormone therapy focuses on specific genes or proteins that help and trigger the growth of cancer cells and regulate hormones like estrogen or progesterone.

What Complications Are Associated with Inflammatory Breast Cancer (IBC)?

As mentioned, IBC is aggressive, and complications occur due to both the disease and its treatments.

Some of the common complications are:

1. Lymphedema. It is the swelling in the arm or chest after lymph node removal.

2. Before diagnosis, the cancer might have spread to other organs.

3. Cancer can cause calcium to enter the bloodstream, potentially leading to the formation of kidney stones.

4. Severe breast pain, changes in skin appearance, and ongoing tenderness.

5. Treatment side effects are nausea, vomiting, fatigue, hair loss, and skin changes.

Conclusion:

Inflammatory breast cancer is an uncommon, rapidly spreading breast cancer that often shows up as redness, swelling, and skin changes rather than a lump, making it difficult to diagnose. It is usually diagnosed at later stages because the symptoms resemble an infection. Recognizing sudden breast changes and getting checked earlier results in early intervention. If you notice any sudden change in your breast, consult a specialist to rule out the condition.

Key Takeaways:

• IBC is a rare, aggressive breast cancer that appears without a lump.

• Inflammatory symptoms, such as swelling, pain, warmth, and skin changes, are often mistaken for an infection.

• It is generally diagnosed at a later or advanced stage.
