Question 4

It is the study of the antigen associated with tumors, the immune response to tumors, the tumor’s effect on the host’s immune status, and the use of the immune system to help eradicate the tumor.

Answer 4

Tumor Immunology

Question 5

Tumor immunology is best to understood with a background on differences between _____ & ______.

Answer 5

Tumor cells;Normal cells

Question 6

It act as central regulators of the growth in normal cells that code for proteins involved in growth and repair processes in the body.

Answer 6

Proto-oncogenes

Question 7

It can cause uninhibited cell division if their expression is altered or if they are mutated.

Answer 7

Protooncogenes

Question 8

The mutations or malfunctions of it remove growth-inhibitory signals can cause tumor.

Answer 8

Tumor suppressor genes

Question 9

It is normally couteract proto-oncogenes by encoding proteins that prevent cellular differentiation.

Answer 9

Tumor suppressor genes

Question 10

It is composed of cells that possess many of the attributes of the normal cells from which they arose but have accelerated or dysregulated growth.

Answer 10

Tumors

Question 11

These are tumors that do not invade surrounding tissue and normal body function is largely preserved

Answer 11

Benign Tumors

Question 12

It can invade surrounding tissues and greatly disrupt normal body function.

Answer 12

Malignant Tumors

Question 13

It is when the malignant cells travel through the body, causing new foci of malignancy until body function is so disrupted that death occurs.

Answer 13

Metastasis

Question 14

This type or tumor is usually encapsulated, Grow slowly, Nonspreading, minimal mitotic activity, and ressemble the parent tissue.

Answer 14

Benign Tumors

Question 15

This type of tumor Increased in number of cels that accumulate, invasion of tissues, Dissemination by lymphatic spread within a body cavity,Metastasis, Nuclear cellular features, Receptors for integrin molecules.

Answer 15

Malignant Tumors

Question 16

It has a receptor for integrin molecules, which help malignant cells adhere to extracellular matrix,type IV collagenases, which dissolve basement membranes, and proteases.

Answer 16

Malignant Tumors
