Lec 44

Question 1

Healthy cell becomes a

before a cancer cell

Answer 1

benign cell

Question 2

benign cell

Answer 2

increase reproduction and eventually becomes a malignant cancer cell/tumor which spreads

Question 3

Cancer incidence

Answer 3

increases as age increases

Question 4

Males mostly have

Answer 4

prostate cancer

Question 5

Females mostly have

Answer 5

breast cancer

Question 6

Cancer type that kills the most

Answer 6

lung cancer

Question 7

what causes the change of a healthy cell to a benign cell and cancer cell

Answer 7

mutations

changes inDNA

Question 8

Initiation

Answer 8

one mutation in one cell causes itself and its offspring to divide inappropriately

Question 9

Progression

Answer 9

More and more random mutations

increase reproduction, survival, and spreading

Question 10

Spread (metastasis)

Answer 10

Cell leave the primary tumor and establishes more tumors

Question 11

Healthy cell to benign cell

Answer 11

Initiation

Question 12

Benign cell to cancer cell

Answer 12

Progression

Question 13

Cancer cell onward

Answer 13

Spreading/metastases

Question 14

Misconceptions about cancer cells

cancer cells are not

Answer 14

trying to get worse

the mutations are random and are mostly bad but can also be bad for the cancer cell

Question 15

Misconceptions about cancer cells

cancer cells do not reproduce

Answer 15

quickly

100 days per cell cycle

Question 16

Healthy human cell reproduce every

Answer 16

24 hours

Question 17

Misconceptions about cancer cells

cancer cells in a tumor are not

Answer 17

Identical

many different mutations from each cancer cell

Each cells have different destructive properties and vulnerabilities

Question 18

Single cell DNA sequencing

Answer 18

would not notice all mutations in cancer cells because they are different

Question 19

Misconceptions about cancer cells

most cells in a tumor are not

Answer 19

Cancer cells

Cancer cells recruit normal cells for support
