6. List a few movies where this occurs: Tell me the name of the movie
Discussion Question…
Have you ever watched a movie in which people play with the elements of nature? These movies are usually “scary” and involve things getting “out of control”.
List a few movies where this occurs:
Tell me the name of the movie
What happens?

7. “OUT OF CONTROL”

8. Growth factors are proteins that stimulate cell division.
Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells.

9. Apoptosis is programmed cell death.
a normal feature of healthy organisms
caused by a cell’s production of self-destructive enzymes
occurs in development of infants
webbed fingers

10. Cancer is the common name for a class of diseases characterized by uncontrolled cell division.
Arises when regulation of the cell cycle breaks down
Continue to divide, may lead to uncontrolled growth

11. Cancer cells do not carry out necessary functions.
Cancer cells come from normal cells with damage to genes involved in cell-cycle regulation.

12. Cancer cells form disorganized clumps called tumors.
Benign tumors remain clustered and can be removed.
Malignant tumors metastasize, or break away, and can form more tumors.

13. Carcinogens are substances known to promote cancer.
Ex: cigarettes, formaldehyde, pesticides, smog, etc….

14. Standard cancer treatments typically kill both cancerous and healthy cells.

15. Cancer treatments
Radiation therapy
chemotherapy
Surgery to remove the cancer

16. Please add new information to your circle map
