The most common symptom is a painless lump on the chest that can be felt near the nipple.
Some of the other warning signs include:
- Discharge from the nipple.
- Changes to the nipple’s shape or appearance.
- Swelling or painful dimpling causing changes in the shape or appearance of the breast tissue.
- Swollen lymph nodes under the arm.
If you notice any of these symptoms, or any unusual changes in your breast that concern you, see a doctor as soon as possible.
