Q

_________ is characterized by uncontrolled growth and spread of abnormal cells.

Cancer

2
Q

What are the 2 types of precancerous cells?

A

Hyperplasia and dysplasia

3
Q

What is the difference between dysplasia and hyperplasia?

A
Hyperplasia = accelerated growth of cells

4
Q

Cancer is classified by the origin, including the type of tissue where it occurs and the primary site of development. The name for a benign tumor ends in _____, while for a malignant tumor it ends in _______.

A
Benign = -oma
Malignant = -sarcoma
5
Q

True or False: A malignant tumor is often encapsulated and rarely recurs once surgically removed.

A

False! These are characteristics of a benign tumor.

6
Q

Malignant cells are ______, meaning that they have different cellular architecture than the cells of origin that are normal.

A

Anaplastic

7
Q
All of the following are internal factors influencing carcinogenesis EXCEPT:
A. Viruses (HIV, HPV, EBV, etc.)
B. Heredity (genetic mutations)
C. Inflammation (immune conditions)
D. Endocrine factors (hormones)
A

A. Viruses (HIV, HPV, EBV, etc.)

8
Q

______ means growth of the same cancer at a distant site from origin.

A

Metastases

9
Q

List the 4 common sites of metastases.

A

Lung, liver, brain, bone

10
Q
There are 4 avenues of spread for cancer to metastasize through the body. Which of the following means that the cancer spreads through seeding of tumor during biopsy?
A. Direct Extension
B. Lymphatic
C. Hematogenous
D. Implantation
A

D. Implantation

11
Q
List 2 of the 4 avenues of metastases that are the most common.
A. Direct Extension
B. Lymphatic
C. Hematogenous
D. Implantation
A

B. Lymphatic

C. Hematogenous

12
Q

True or False: Malignant cells secrete mediators that stimulate formation of blood vessels for growth and oxygen (and they thrive on this).

A

True

13
Q
Which of the following is NOT a risk factor for cancer development?
A. Older age
B. Smoking
C. Unhealthy diet
D. High cholesterol
E. UV exposure
F. Family history
A

D. High cholesterol

14
Q

True or False: Geographical location plays a role in higher cancer mortality.

A

True

15
Q

The most commonly diagnosed cancer annually is ___ in women and _____ in men.

A

Breast cancer in women

Prostate cancer in men

16
Q
The most common cause of death from cancer annually is from which type of cancer?
A. Lung cancer
B. Colon cancer
C. Pancreatic cancer
D. Leukemia
E. Oral cancer
A

A. Lung cancer

17
Q

In diagnosing cancer, one must look at signs and symptoms, laboratory tests, imaging, tissue sample, and staging. In terms of staging, which is better?
A. G1 - well differentiated
B. G4 - Undifferentiated

A

A. G1 - well differentiated

Because it develops slower and looks more like normal cells.

18

N: Nagging \_\_\_\_\_ or abscess
A
