Genetic Damage

Question:

What exactly is damaged when

genetic damage occurs?

Page 3: Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation.

Answer: The genes in the normal cells are

damaged. Cancer results from the

accumulation of genetic damage to

cells across time.

Page 4: Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation.

Cancer Cells vs. Normal Cells

Question:

How are cancer cells different from

normal cells?

Page 5: Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation.

Answer:

1.Shape changes2.Changes in their

dependence on growth factors

3.Multitude of biochemical differences

Page 6: Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation.

Cancer is a Multi-Step Process

Question:

What are three cancer facts that

support the theory that cancer is a

multi-step process?

Page 7: Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation.

Answer:

1. Increased incidence of cancer with age

2. Development of cancer decades after exposure

3. Increased incidence of cancer among people with inherited dispositions
