Breast Cancer & The Environment

Types of Breast Tumors

 Benign:

  • Usually not harmful
  • Rarely invade the tissues around them
  • Don't spread to other parts of the body
  • Can be removed and usually don't grow back

Malignant

  • May be a threat to life
  • Can invade nearby organs and tissues (such as the chest wall)
  • Can spread to other parts of the body
  • Often can be removed but sometimes grow back

 

Definition of breast cancer: Cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.
