Week 1 - Study Guide Questions Flashcards
1
Q
what is contact inhibition
A
- this is one of the ways that cellular proliferation is controlled
- normal cells respect the boundaries of the cells surrounding them & will not invade territory that is not their own
- cancer cells lack contact inhibition & will grow on top of other cells
2
Q
what is proliferation
A
- cell growth & division
3
Q
what is differentiation
A
- an orderly process where the cell progresses from a state of immaturity to a state of maturity
- kinda like specialization
4
Q
define malignant
A
- cancerous
- cells with invasive and metastatic potential
- cells are poorly differentiated
5
Q
define neoplasm
A
- tumour
- abnormal mass of cells which grow & divide without response to normal regulatory controls
6
Q
define benign
A
- a tumour with limited potential for growth and metastasis
- cells are well differentiated
- non cancerous
7
Q
define carcinogen
A
- cancer-causing agents that are capable of causing cellular alteration
8
Q
define pancytopenia
A
- low levels of RBC, WBC, and platelets
9
Q
what are colony stimulating factors?
A
- family of glycoproteins produced by various cells
10
Q
what is the function of colony stimulating factors
A
- stimulate production, maturation, regulation, and activation of cells of the hematological system
11
Q
what is radiation theraoy
A
- local treatment for cancer
12
Q
in what situations would chemotherapy be utilized?
A
- when the cancer is disemmiated/systemic
13
Q
what is the main goal of radiation therapy?
A
- cure, control, and palliation
14
Q
list 3 differences between radiation & chemo in terms of their effect on the body & cells
A
- admin of radiation results in limited ability to normal cells to recover from damange & potential irreversible effects = ex. hair will not grow back but will in chemo
- in radiation, only cells in the radiation field will be affected by treatment. in cancer, it is systemic
