Webquest: Investigating Different Types of Cancer A CLOSER LOOK AT CANCER Some activities in life are highly regulated. For instance, think about an amusement park. Some rides in the park are restricted to people of a certain height or age. Every ride can only hold a certain number of people, so visitors must wait for their turn. Each part of the park is regulated. Imagine the chaos that would erupt if everyone broke the rules. In our bodies, the cell cycle is highly regulated. Cells grow, divide, and die in regulated steps. But sometimes, damaged cells break the rules and reproduce unchecked, causing cancer. In this activity, you’ll learn about cancer and how it relates to the cell cycle. Did you know that more than one million people in the United States are diagnosed with some form of skin cancer every year? Imagine that you have a friend who is constantly getting sunburned, and you want to convince your friend to take precautions in the sun. What would you say?

What is the normal function of that body part? 4. What are some of the risk factors associated with contracting this cancer? 5. What are the most common signs/symptoms of this disease? 6. How is it detected and/or diagnosed? 7. What is the rate of survival for this type of cancer (you might need to discuss different stages)? 8. What is the most commonly recommended type of treatment for this cancer? 9. Describe some side effects of the treatment. 10. List at least 2 statistics involving this type of cancer.
