NEOPLASMS- Cancerous or Benign

• Cell divides rapidly (cancerous or benign)

• An abnormal mass of tissue that results when cells divide more than they should or do not die when they should.

• Neoplasms may be benign (not cancer), or malignant (cancer). Also called tumor.

Hyperplasia

• Tissues enlarge because of a stimulus that irritates the cells

• Instead of finding a benign or malignant tumor, microscopic examination of a biopsy specimen will sometimes detect a condition called "hyperplasia."

• Nonetheless, cell structure and the orderly arrangement of cells within the tissue remain normal, and the process of hyperplasia is potentially reversible.

• An example of hyperplasia is a callus that may form on your hand when you first learn to swing a tennis racket or a golf club.
