1

What is the second leading cause of death in North America?

Cancer

2

Why is early detection of cancer problematic?

It can spread rapidly

3

Why is CAUTION not particularly helpful?

It's very vague

4

CAUTION stands for the following:

Change in bowel or bladder habits
A sore that does not heal
Unusual bleeding or discharge
Thickening or lump in the breast or elsewhere
Indigestion or difficulty in swallowing
Obvious change in a wart or mole
Nagging cough or hoarseness

CAUTION stands for the following:

Change in bowel or bladder habits
A sore that does not heal
Unusual bleeding or discharge
Thickening or lump in the breast or elsewhere
Indigestion or difficulty in swallowing
Obvious change in a wart or mole
Nagging cough or hoarseness

5

What occurs when normal body cells lose the ability to control their division?

Cancer

6

What are the normal processes in our body in place to prevent uncontrolled cell division in the body?

Apoptosis

7

How do DNA mutations in cells usually prevent cancer cells from dividing?

They trigger certain proteins to be produced that stop the cell from diving and often kills the cell

8

Why is it difficult for our immune system to recognize and kill cancer cells?

They are their own body cells

9

Is it true that everyone has cancer?

Yes

10

According to the conventional wisdom, what is the main/core cause of cancer?

Random genetic mutations

11

Which part of the cell is damaged that leads to cancer?

The DNA

12

What are 3 potential causes of damage to DNA?

1. Uncontrolled Cell Replication
2. Lack of Apoptotic Signaling
3.Increased Invasive and Metastatic Properties

13

What percent of cancers are thought to be attributed to genetic predisposition?

60%

14

What percent of cancers are thought to be due to environmental causes?

40%

15

What are 3 environmental causes of cancer?

1. Toxins
2. Low antioxidant intake
3. Poor diet

16

What are masses of cells that can be cancerous or noncancerous?

A Tumor

17

What are noncancerous tumors that do not spread?

Benign

18

What is property of spreading locally and to distant sites?

Malignant

19

What is the spreading of disease from the site of the original tumor to parts of body that are remote?

Metastasize

20

What are the 3 main ways that we treat cancer?

Surgery, Chemotherapy, and Radiation

21

What characteristic of cancer cells is different from most normal cells that is used to target cancer cells?

Cancer cells rapidly divide while most normal cells don’t

22

What uses drugs that interfere with a cell’s ability to divide?

Chemotherapy

23

What are the 3 common mechanisms of chemotherapy

Impair DNA synthesis, trigger cell death, and stop growth of new blood vessels

24

What is a side effects associated with Chemotherapy?

The treatments targets important cells for your body that also rapidly divide

25

What important cells does Chemotherapy also target?

Immune cells and intestine cells

26

What are 5 of the symptoms associated with cancer?

Hair loss, nausea, vomiting, chronic infections, skin problems

27

Are the symptoms associated with cancer caused by the cancer or the cancer treatment?

The cancer treatment

28

What uses high-energy radiation to damage and kill cancer cells?

Radiation

29

What is a side effect of radiation treatment?

It can cause cancer

30

How are free radicals thought to contribute to cancer susceptibility?

They damage DNA
