My breast has a lump and it hurts

Breast tissue can feel lumpy or sore with hormonal changes, a cyst, inflammation, an injury, or changes related to breastfeeding. Pain does not identify the cause. A breast lump is a common presentation of breast cancer, but many breast lumps are benign; only an examination and, when needed, imaging or sampling can clarify what is happening.

Tell the clinician whether the lump changes with your menstrual cycle, whether the skin is hot or red, and whether you are breastfeeding. Note any nipple discharge, skin dimpling, or change in breast shape.

Book an appointment for a new lump, a lump that remains after your period, or pain that is not settling. Avoid repeatedly pressing the area because this can increase tenderness. Wear a supportive bra if comfortable, and use a simple pain reliever only if it is suitable for you and used according to its instructions. Do not delay assessment because the lump is painful or because it feels smooth.

A clinician may examine both breasts and the nearby lymph nodes, then decide whether imaging or a sample is needed. Read more about [Breast Cancer](/conditions/breast-cancer/) for context, while remembering that a symptom page cannot determine your diagnosis.

Seek urgent advice for a hot, red, rapidly swollen breast with fever, severe worsening pain, or feeling unwell, particularly while breastfeeding. Arrange prompt review for bloody nipple discharge, skin dimpling, a nipple turning inward, a firm fixed lump, or a new lump in the armpit. These signs need examination; they do not establish a diagnosis by themselves.

Ask what the examination suggests, whether the timing of your cycle or breastfeeding changes the assessment, and which imaging test is appropriate. Ask when to return if the lump persists, what changes to monitor, and how to manage pain safely while you wait.
