The cause of breast cancer is not known. Most researchers think that the
disease results from a combination of genetic factors and environmental
influences

Breast cancer has no symptoms in its earliest stages. The first noticeable
symptoms may include:

• A lump or thickened area in the breast large enough to be felt
  during a breast self-examination.
• A watery, bloody, or yellowish discharge from the nipple.
• A change in the shape or size of the breast.
• A flattened, puckered, or indented area in the skin of the breast.
• An orange-peel appearance to the skin of the breast.
