Breast Cancer

This cancer forms in tissues of the breast. The most common type of breast cancer is ductal carcinoma, which begins in the lining of the milk ducts, the thin tubes that carry milk to the nipple. Another type of breast cancer is lobular carcinoma, which begins in the lobules—milk glands—of the breast. Invasive breast cancer is breast cancer that has spread from where it began in the breast ducts or lobules to surrounding normal tissue. Breast cancer occurs in both men and women, although male breast cancer is rare.

Female Symptoms:

  • A lump or thickening in or near the breast or in the underarm area
  • Changes in the size or shape of the breast
  • A dimple or puckering in the skin of the breast
  • A nipple turned inward into the breast
  • Fluid, other than breast milk, from the nipple—especially if it’s bloody
  • Scaly, red or swollen skin on the breast, nipple or areola (the dark area of skin that is around the nipple)
  • Dimples in the breast that look like the skin of an orange, called peau d’orange

Male Symptoms:

  • A lump in or near the breast that can be felt


Different treatments are available for patients with breast cancer, including clinical trials of new treatments for patients with cancer.
