17925 Inflammatory Breast Cancer
Informed by recognized medical guidance
Overview
Inflammatory breast cancer is a rare, aggressive type of breast cancer. It causes the breast to look red, swollen, and warm — often like an infection. This happens because cancer cells block small vessels called lymph vessels in the skin of the breast.
Key facts
- It is rare but grows quickly.
- It may not cause a lump like typical breast cancer.
- It needs urgent medical attention because it can spread rapidly.
- Treatment usually combines chemotherapy, surgery, and radiation therapy.
No. Inflammatory breast cancer is rare. It makes up less than 5% of all breast cancer cases.
It mainly affects women, but men can also get it. It tends to be diagnosed at a younger age than other breast cancers, but anyone with breast tissue can be affected.
Symptoms
- Call your local emergency number if you have sudden chest pain, trouble breathing, or coughing up blood. These can be signs of a blood clot, which can happen with cancer or its treatment.
- ⚠See a doctor the same day if you have any new redness, swelling, warmth, or thickening in your breast, especially if it gets worse within a few days.
Common symptoms
- Redness covering a third or more of the breast
- Swelling or enlargement of the breast
- Warmth or heat coming from the breast
- Skin that looks like the skin of an orange (dimpled, pitted)
- Breast pain, tenderness, or aching
- Retracted (inverted) nipple
- Swollen lymph nodes under the arm or near the collarbone
Causes
Main causes
- The exact cause is not fully understood.
- Inflammatory breast cancer grows from breast cells that become abnormal and multiply quickly.
- It blocks lymph vessels in the skin, causing redness, swelling, and warmth.
Risk factors
- Being female
- A family history of breast cancer
- Certain inherited gene changes, such as BRCA mutations
- Obesity
- A personal history of breast cancer
When to see a doctor
See a doctor urgently if:
- Any area of redness, swelling, or warmth on your breast that appears suddenly and spreads
- Breast skin that looks like the skin of an orange (dimpled)
- A breast that feels unusually firm, tender, or larger than the other side
Book a routine appointment if:
- Persistent breast pain or itching without a clear cause
- Nipple changes such as turning inward or discharge
Diagnosis
To diagnose inflammatory breast cancer, a doctor will examine the breast and take a sample of tissue (biopsy) to look for cancer cells. Imaging tests help show how much the breast tissue is affected.
Tests that may be done
- Breast exam
- Mammogram
- Ultrasound
- Breast MRI
- Biopsy (taking a small piece of tissue, often from the skin and breast)
What to expect at your appointment
The process usually starts with an urgent referral to a breast clinic. You may have several tests in one visit. Results can take a few days. If cancer is found, your care team will talk with you about the next steps.
Treatment
Treatment for inflammatory breast cancer usually starts with chemotherapy — medicine that kills cancer cells — to shrink the cancer. Surgery and radiation therapy often follow. Your care team will tailor the plan to your situation.
Self-care at home
- Follow your treatment plan and attend all appointments
- Talk with your healthcare team about any side effects
- Rest when you need to and accept help from others
Medical treatments
Common approaches include chemotherapy before surgery, surgery to remove the breast (mastectomy), radiation therapy to the chest wall, and sometimes targeted drug therapy or hormone therapy — depending on the cancer's features. Your specialists will explain what they recommend.
When is surgery considered?
Most people with inflammatory breast cancer have a mastectomy — removal of the entire breast — after chemotherapy. Nearby lymph nodes are also often removed. Breast reconstruction is usually delayed until after radiation therapy.
Living with this condition
Living with inflammatory breast cancer involves frequent appointments and managing treatment side effects. Many people find it helpful to set small goals, keep a notebook for questions, and lean on loved ones.
Lifestyle tips
- Try gentle movement like short walks, if your energy allows
- Get rest when you are tired
- Reach out to support groups or counselling
Diet and exercise
Eat a balanced diet with plenty of protein and vegetables to help your body during treatment. Talk to a dietitian or your care team if you have trouble eating. Light exercise can help your energy, but check with your doctor first.
Mental health and emotional wellbeing
A diagnosis of inflammatory breast cancer can bring fear, anxiety, and sadness. These feelings are normal. Speaking with a counselor, social worker, or support group can help you cope. If you have thoughts of harming yourself, call your local emergency number right away.
Prevention
There is no known way to prevent inflammatory breast cancer. The focus is on early detection and prompt treatment, since the cancer grows quickly.
Vaccines
There is no vaccine to prevent inflammatory breast cancer.
Screening programmes
Standard breast screening, including mammograms, can find some breast cancers early. However, inflammatory breast cancer can appear between screenings. This is why it's important to know your breasts and report any persistent change to a doctor right away.
Complications
If left untreated
- The cancer can spread quickly to other parts of the body
- Lymph vessels in the skin can become increasingly blocked, causing pain and skin changes
- It can become more difficult to treat successfully once it has spread
Long-term outlook
Inflammatory breast cancer is serious, but it is treatable. With prompt diagnosis and a full course of treatment, many people live well for many years. Researchers are continuously improving treatments and giving hope to those affected.
