True
False


2. In order for a cancer to develop, cells must be capable of breaking away from neighboring cells and they must ignore growth inhibitory signals from other cells, resulting in uncontrolled growth and cell division. (Points: 1)

True
False


4. Unlike traditional vaccines, most cancer vaccines are administered to an individual after they have developed the illness. (Points: 1)
True

potentially migrate to other locations in the body.
have an enlarged nucleus.
lose the ability to control cell division.

11. Which enzyme is a potentially useful indicator of certain types of cancers? (Points: 1)
antioxidants
trypsin

12. Which of the following is not true regarding the immune system and cancer? (Points: 1)
Some cancers can suppress the immune system.
Some cancer cells produce abnormal proteins on their cell surfaces that the immune system can use to detect these cells.
Cancer cells can be killed by immune system cells.
Because cancer cells are the individual's cells, there is no way for the immune system to differentiate between normal cells and cancer cells.
Many cancer cells do not display "self" proteins.


13. Which of the following is true regarding chemotherapy? (Points: 1)
This technique is used in the diagnosis of cancer.
This procedure kills cancer cells and normal cells that divide rapidly.
This is the selected technique in the treatment of cancer because there are no side effects.
This is a procedure used to genetically engineer an individual so cancer will not develop.
Most chemicals used in this procedure only affect one organ of the body.

prostate
skin
colon


15. Which of the following is not true regarding cervical cancer? (Points: 1)
The Pap test can be used to diagnose cervical cancer.
The risk of developing cervical cancer increases with infection by the herpes simplex virus.
Cervical cancer may be one of the first cancers to be prevented with the use of a vaccine.
Women with multiple sex partners are at higher risk for cervical cancer.
The survival rate for women with cervical cancer is fairly high.
