Hyperplaisia
Noncanerous growth consisting of rapidly dividing cells leading to an increased number of normal cells
Mild Displasia
Noncanerous abnormal cell growth characterized by the loss of normal tissue arrangement and cell structure
Cells may have changes in DNA and/or
Cells may have structral changes in the nuycleus
Carcinoma in situ
in situ (latin for in location or place)
Unctolled cell grwoth that remains in locatio or place
(does not invade surrounding tissue)
Cancer
Unctrolled cell growth and invasion into surrounding tissue
Feature of Cancer
Not a single disease
Over 100 types and subtypes of human cancer
Indiscriminant
Leading casue of death worldwide
affects 2 of every 3 families
Main types of cancer and overall mortality
Lung- 1.3 million deaths yearly
Stomach- ~1 million deaths yearly
Liver- ~662K deaths yearly
Colon- ~665K deaths yearly
Breast- ~502K deaths yearly
Tumor
Swelling
Describes the severity of a person's cancer based on the extent of the orginal (primary) tumor and whether or not cancer has spread in the body
Why is tumor staging important
Helps doctor plan the appropriate treatment
Can be used to estimate a patient’s prognosis
Important in identifying clinical trials that may be suitable for a particular patient
Helps health care providers and researchers exchange information about patients
Provides common terminology for evaluating and comparing the results of similar/dissimilar clinical trials
•TMN staging system based on
•Tumor (T) -Extent of the tumor
•Nodes (N) -Whether cancer cells have spread to nearby (regional) lymph nodes
•Metastasis (M) - Whether distant (to other parts of body) metastasis has occurred
Neoplasia
New Growth
What is the tissue of origin (epithelial cells or connective tissues)
•Tumor (T) -Extent of the tumor
•Nodes (N) -Whether cancer cells have spread to nearby (regional) lymph nodes
•Metastasis (M) - Whether distant (to other parts
of body) metastasis has occurred
2 types of tissue of orgin
epithelial cells or connective tissues
Benign tumors are considered
noncancerous, localized to a tissue, and end in oma
Malignant tumors consist of
rapidly dividing cells, invade normal tissue, metastasize to distant sites, and end in carcinoma or sarcoma
Epithelial Cells and Benign

four factors that regulate normal cell growth and repair damaged tissue
Growth factors
Growth inhibitors
Cyclins - Cell Cycle Proteins
Apoptosis - Programmed cell death, a normal componet of the development and health of mulitcellular organisms
