4. Persistent Pain or Sensitivity
Breast cancer doesn’t always cause pain, but some women experience persistent discomfort, burning, or tenderness in a specific area of the breast or armpit. If pain doesn’t go away and remains localized, it should be examined—even if it resembles menstrual or muscular pain.
5. Nipple Changes
The nipple can reveal important clues. Watch for inversion (nipple pulling inward), shape changes, redness, flaking, or crusting. Any discharge that is not breast milk—especially bloody or unusually colored fluid—should never be ignored.
6. Abnormal Nipple Discharge
Spontaneous nipple discharge when not breastfeeding always requires medical evaluation. It may appear yellow, green, or reddish and can signal changes in the milk ducts. Discharge that occurs without squeezing the nipple is particularly concerning.
7. Swelling or Lumps in the Armpit or Neck
Breast cancer can spread to nearby lymph nodes, especially in the armpit. A hard, painless lump or swelling in this area may indicate lymphatic involvement. While infections can also cause swollen nodes, persistent swelling should be checked.
