not excessive to needs
purposeful
ceases when stimulation ceases
reversible
regulated - Characteristics of neoplasia
-
excessive
purposeless
persistent
irreversible
autonomous - Characteristics of Benign Neoplasms
-
no metastasis
grows by uniform expansion (not invasive)
resembles tissue of origin
well circumscribed, often encapsulated
progressive, slow growth
normal mitotic figures
excision usually curative
adequate blood supply - Characteristics of Malignant Neoplasms
-
metastasis
grows by expansion & infiltration (invasive)
poorly differentiated (may be anaplastic)
slow to rapid growth
abnormal, abundant mitotic figures
local recurrence frequent
often outgrows blood supply & becomes necrotic - Cytologic characteristics of malignant cells
