What breast changes should I see a doctor about?

Bottom lineSee a doctor promptly about a new lump in the breast or armpit, skin dimpling or orange-peel texture, redness or swelling, new nipple inversion or discharge, one-sided persistent pain, or a change in breast size or shape; most changes are benign, but that call belongs to a clinician, not to waiting.

See a clinician promptly - within days to a couple of weeks, not months - about any of these changes:

Lumps and texture

• A new lump or hard knot in the breast or armpit, especially one that feels different from surrounding tissue
• A lump that persists through a full cycle instead of shifting with your hormones
• New thickening of an area of breast tissue

Skin changes

• Dimpling, puckering, or pulling of the skin
• Redness, warmth, or swelling, with or without a lump
• Skin with an orange-peel texture (thickened with enlarged pores)
• A rash or scaling, especially around the nipple

Nipple changes

• A nipple that has newly turned inward or changed position
• Discharge without squeezing, especially if bloody or from one breast only

Pain and size

• Persistent pain in one spot that does not track with your cycle
• A noticeable change in the size or shape of one breast

Keep it in perspective

Most of these changes turn out to be benign - cysts, fibroadenomas, infections, and hormonal changes are all far more common than cancer. Cyclical tenderness in both breasts before your period is normal. But "probably benign" is a judgment for a clinician with an exam and imaging, not for waiting and hoping. If a change is still there after your next period, or it worries you now, book the appointment - and keep routine mammograms regardless, since self-checks never replace screening.
