Question 1

Neoplasm:

Answer 1

Growth that proliferates with varying degrees of independence from normal cellular control mechanisms, presumed to arise by mutation or altered genetic control, behaves as if they were an independent parasitic organism.

Question 2

Hyperplasia:

Answer 2

Exaggerated response to stimulus or presumed stimulus resulting in increased cell numbers ( not size: hypertorphy) which often recede when stimulus is removed

Question 3

Tumor:

Answer 3

Originally a swelling or mass, has come to be used as synonym for neoplasm

Question 4

Benign neoplasm:

Answer 4

Encapsulated, single masses of cells that remain localized at their site of origin and limited in their growth (though some can become very large and or multiply and cause serious disease)

Question 5

Malignant neoplasm:

Answer 5

A tumor that tends to grow, invade and metastasize, usually has an irregular shape and is composed of poorly differentiated cells (ability to specialize)

Question 6

Cancer:

Answer 6

any of a large group of malignant neoplastic diseases characterized by the presence of malignant cells

Question 7

Oma:

Answer 7

Suffix added after the name of the tissue in which a neoplasm exists, usually benign (fibroma, lipoma, hematoma) exceptions

• carcinoma
• sarcoma
• Adenoma
• lymphoma
• Melanoma
• Glioma
• Myeloma

Question 8

Carcinoma:

Answer 8

Malignant neoplasm of epithelium

Question 9

Sarcoma:

Answer 9

Malignant neoplasm of non-epithelial tissue

Question 10

Adenoma:

Answer 10

Malignant neoplasm of epithelial and glandular tissue

Question 11

Lymphoma:

Answer 11

malignant neoplasm of lymph node cells (lymphatic tissues)-no benign counterpart

Question 12

Melanoma:

Answer 12

Malignant neoplasm of melanocytes ( Nevus-birthmark/beauty mark- is the benign counterpart)

Question 13

Glioma:

Answer 13

Neoplasms of supporting cells (glial cells) of brain (benign in that they don’t spread, malignant in that they usually kill the pt

Question 14

Myeloma:

Answer 14

Neoplasma of plasma cells

Question 15

Neoplasms that dont form tumors

Answer 15

• Leukemia: neoplasms of lymphocytes

- Erythroleukemia: neoplasms of RBC’s

Question 16

Invasion:

Answer 16

Direct extension of neoplastic cells into surrounding tissue without regard to tissue boundaries

Question 17

Metastasis:

Answer 17

Transportation of cells to a new site(through vascular or lymphatic channels, accidental surgical transplantation or by local extension.

Question 18

Seeding:

Answer 18

INvasion of natural body cavity

Question 19

Primary site:

Answer 19

original location of neoplasm

Question 20

Secondary site:

Answer 20

Tumor growth not connected with original neoplasm (metastasized)
