What are the symptoms of invasive breast cancer?

Screening mammograms may help detect breast cancer before it causes any symptoms. However, screening mammograms may miss breast cancer that is already present. Invasive breast cancer symptoms may include:
  •  A lump or mass in the breast.
  •  Swelling of all or part of the breast, even if no lump is felt.
  •  Skin irritation or dimpling.
  •  Breast or nipple pain.
  •  Nipple retraction (turning inward).
  •  The nipple or breast skin appears red, scaly or thickened.
  •  Nipple discharge.
  •  A lump or swelling in the underarm lymph nodes.
Knowing the signs and symptoms of breast cancer is essential to early diagnosis.
