Health Restoration Exam 1 Questions With
Verified Answers
Parental - answer✔outside of your gut
men - answer✔is cancer higher in men or women?
cancer - answer✔group of of disease characterized by uncontrolled and unregulated growth of
cells
defective cell proliferation - answer✔(growth) grow so fast, out of control
on/off switches (mutation is on all the time-facuet on all the time, ex bleed= hemoglobin is at 7
then when u get back to 12 off switch says ok thats enough but with cancer it just doesnt stop.
Defective cell differentiation - answer✔so many WBC but they are broken so they dont work
two types-
1. proto-oncogenes
2. tumor suppressor genes
proto-oncogenes - answer✔Regulate normal promotion of growth (on switch) GO
Such as:
•ultrasounds, MRI's, imaging, labs, mammograms, cancer screens, getting blood work
Tertiary (treats) (cancer) - answer✔-monitoring & preventing reoccurrence of primary cancer
-screening for secondary malignancies in cancer survivors
Flares - answer✔Things that attach
Oncogene - answer✔"Bad gene"
Cancer producing gene
Proto-oncogene - answer✔Gene capable of becoming cancer producing gene
Lose normal regulating functions
On switch- multiplication
'Ras' Rat Sarcoma - answer✔Normal family of genes involved in controlling cell growth and
death
When mutates it's a permanent turn on cell
Proto-oncogene examples - answer✔ERBB2- breast cancer
BRAF- melanomas
BCR-ABL- CML
KRAS- esophagus, colon, pancreas
Apoptosis - answer✔Natural destruction of cells when they reach their life span
TP53 tumor suppressor gene - answer✔Slow cell division, repair DNA, apoptosis
When suppressor gene mutates- no brake, cells grow out of control
Tumor suppressor causes cancer when they are inactivated (turned off)
Tp53 examples - answer✔P53- mapped to chromosome
BRCA1/ BRCA2 genes- responsible for 5-10% of breast cancer
APC gene- colon cancer
TSA (tumor specific antigens) - answer✔1. Tumor burden - how much cancer is in a person
2. RX- treatment, see if reoccurrence
Malignant neoplasms - answer✔Undifferentiated, mitosis more rapid (oncogenes), no growth
suppression signals
-gensis - answer✔Birth of blood vessels
Neoplasms spread by... - answer✔Invasion - growth into surrounding tissues
Metastasis- spread from primary to distant sites
Tumor escape mechanism - answer✔Disgusted and camoflouaged
Weak surface allows Cancer cells to sneak through surveillance
Hematogenous spread - answer✔Related to vascularity of tumors
Attach to endothelium
Allows cancer cells to enter basement membrane
Lymphatic spread - answer✔Most common- metastasis
Communicated w lymphatic fluid
Angiogenesis (growth of new blood vessels) - answer✔When tumor increases in size, developing
new blood supply is critical to survival and growth
Seven warning signs of cancer - answer✔1. A change in bowel or bladder habits
2. A sore that does not heal
3. Any unusual bleeding or discharge
4. A thickening or lump
5. Indigestion or difficulty swallowing
6. An obvious change in a wart or a mole
7. A nagging cough or hoarseness
Tumor classification system - answer✔Grading- cell differentiation
Staging- extent of disease
Provide standardized way to....
1. Communicate status of cancer
2. Assist in effective Tx plan
