Biomedical Technology Cellular Biology and Cancer Objective 3 Genetic damage and mutation

Genetic Damage Question: What exactly is damaged when genetic damage occurs?

Answer: The genes in the normal cells are damaged. Cancer results from the accumulation of genetic damage to cells across time.

Cancer Cells vs. Normal Cells Question: How are cancer cells different from normal cells?

Answer: Shape changes Changes in their dependence on growth factors Multitude of biochemical differences

Cancer is a Multi-Step Process Question: What are three cancer facts that support the theory that cancer is a multi-step process?

Answer: Increased incidence of cancer with age Development of cancer decades after exposure 3. Increased incidence of cancer among people with inherited dispositions
