A raw/open area on the breast should be examined in person as soon as possible, preferably within 24-48 hours by a general surgeon, breast clinic, or dermatologist. The cause can range from friction, eczema, injury, or infection to an ulcer caused by an underlying breast lump. Breast-skin ulceration is also a possible sign of breast cancer, so it should not be treated as a simple wound without assessment. Schwartz’s Principles of Surgery notes that breast skin ulceration or erythema can be a presenting sign of breast cancer.
Until you are seen
- Rinse gently with clean water or normal saline; pat dry.
- Cover with a sterile non-stick dressing. Change it if wet or soiled.
- Do not apply steroid creams, antibiotic powders, herbal products, or hydrogen peroxide unless prescribed.
- Avoid rubbing, tight bras, squeezing, or removing adherent tissue.
- Use paracetamol/acetaminophen for pain if you can take it safely.
The clinician may need to do
- Breast and axillary-node examination.
- Ultrasound and/or mammogram, depending on age and findings.
- Swab only if there is discharge suggesting infection.
- Biopsy of a persistent, unexplained, or suspicious ulcer/edge of lesion.
- Cause-specific treatment: proper wound dressing, antibiotics only if infection is present, drainage if an abscess is found, and cancer-directed treatment if indicated.
Seek emergency care today if you have fever, rapidly expanding redness/warmth, pus or foul smell, severe or worsening pain, heavy bleeding, black tissue, a rapidly enlarging breast, or feel unwell. The NHS similarly advises urgent assessment for an open ulcer with hot/red swollen skin, pus, fever, or severe pain.
Please tell me: how long it has been present, its size, whether there is a lump or nipple change, and whether it is bleeding/discharging or associated with fever.
