Inflammatory Breast Cancer: Urgent Signs
Inflammatory breast cancer (IBC) is a rare but aggressive form of breast cancer. Unlike most breast cancers, it often does not form a distinct lump. Instead, it causes the breast to become red, swollen, warm and tender — sometimes with skin that looks dimpled like orange peel — developing over days to weeks. It needs urgent assessment.
What is inflammatory breast cancer?
Inflammatory breast cancer occurs when cancer cells block the small lymphatic channels in the skin of the breast, causing the inflammation-like appearance. Because it can resemble an infection, it is sometimes mistaken for mastitis. The key difference is that IBC does not fully resolve with antibiotics.
Why prompt assessment matters
IBC develops quickly, so early diagnosis is important. If you have rapidly developing breast redness and swelling — particularly if it has not settled with a course of antibiotics — seek assessment urgently. Our team can arrange rapid imaging and biopsy.
When to seek medical advice
See a doctor promptly — or call 999 if you feel acutely unwell — if you notice any of the following:
- Rapidly developing breast redness and swelling
- Skin that looks like orange peel
- A breast that is warm, hard or visibly enlarged
- Symptoms that do not settle within a week of antibiotics
- Nipple flattening or new inversion with skin change
Most breast changes are not cancer. But any new or persistent change should be assessed. Our one-stop breast clinic offers same-day specialist assessment.
Frequently asked questions
How is inflammatory breast cancer different?
Inflammatory breast cancer (IBC) is a rare, aggressive form that often does not cause a distinct lump. Instead it causes redness, swelling and skin changes that can develop over days to weeks, and it needs urgent assessment.
Could my red, swollen breast just be an infection?
Many red, swollen breasts are due to infection (mastitis), particularly when breastfeeding. But if symptoms do not settle quickly with antibiotics, IBC must be excluded urgently.
How is it diagnosed?
Diagnosis involves examination, imaging (mammogram and ultrasound, sometimes MRI) and a biopsy of the breast tissue and skin. This is arranged urgently.
