  • do not spread away from the primary focus
  • remain differentiated - similar to tissues of origin.
  • effects due to increased size, but not to metastases.
     

2

anaplasia

less differentiated; losing recognizability as the tissue from which they originated

2

carcinoma

malignant neoplasm derived from epithelial cells

(most commonly occurring  type of cancer)
