Neoplasms Flashcards
(30 cards)
Increased growth or number in cells
Hyperplasia
A primitive cell that matures into a specific type of cell
Cell differentiation
Increased size of cells
Hypertrophy
Decreased production of cells
Hypoplasia
No production of cells
Aplasia
Lack of production of an organ
Agenesis
Cells have Revered back to its non-differentiated or primitive form
Anaplasia
Cells that appear abnormal microscopically
Dysplastic or atypical cells
New growth that is abnormal and serves no purpose
Neoplasia
Spread to other body parts of the lymph or blood system and establishes growth of new tumors
Metastasis
The cancer is not spreading it is localized has not broken through underlying tissue
Cancer in situ
A space occupying lesion which causes pressure on organs which causes dysfunction
A solid tumor
A new growth that is not confined to a local mass example leukemia
Diffuse neoplasia
To know causes of cancer
Carcinogens and radiation
Five possible causes of cancers
Viruses, genetics, environment, hormones, and immune deficiencies
What are epithelial cells? Where are they found? What are they called if they become malignant?
They are skin cells they’re found an internal organs glands as well as linings of the body cavities they are called carcinoma
What is connective tissue and name three types
Bone muscle and blood
Malignancies of connective tissue are termed?
Sarcomas
Difference between grading and staging of cancers
Grading refers to severity of malignancy versus to staging which refers to degree of spread and amount of metastasis and secondary tumors
How is grading of cancers done
On a 1 to 4 scale 1 being well-differentiated 4 for dedifferentiated
How is staging of cancers viewed
Follows a T N M protocol
Two ways pressure necrosis is a clinic aspect and sign of neoplasia
Mechanical and interference of blood supply
Clinical aspects and signs of destruction in neoplasia a
Weakened bones causing pathological bone fractures
Clinical aspects and signs of pressure necrosis in neoplasia
Lesions resulting from organs causing pressure and death to tissue.
