Inflammatory breast cancer (IBC) is an aggressive breast cancer that often looks different from other types of breast cancers. It may not cause a distinct lump, and its warning signs can often look like mastitis (an infection of the breast).
On IBC Awareness Day, we're sharing key warning signs to know and highlighting efforts to improve how IBC is identified. Greater awareness among both patients and health care providers can help support earlier and more consistent diagnosis and get people the treatment they need faster.
