Part I—"Soaking Up the Sun" Questions
1. What are some differences between Judy and Mariah that might make Judy more "at risk" for skin cancer than Mariah? (2 points)
There are quite a few differences between Judy and Mariah that makes Judy more "at risk" for skin cancer than Mariah. Judy is a fair skinned red head. Mariah was described by Judy as a "Greek goddess" who seemed to enjoy lying in the sun every summer. The sun made Judy's skin red and itchy. The sun made Mariah's skin darker. Red heads are at a much higher risk of getting melanoma because they have a specific natural variation of the MC1R gene that is responsible for producing proteins that appear on melanocytes. These melanocytes are what produce pigment. Darker skinned individuals have the sun protective pigment called eumelanin while red heads have the pigment pheomeloanin which offers no protection and allows the DNA to become damaged from the sun.
2. What observations did Judy make concerning her mole? How could they have used the ABCDE’s of skin cancer assessment to further assist their observations? (2 points)
Judy observed that her mole was itchy and red. She had had it since she could remember, but it looked different. It was darker and the edges looked jagged. If she knew the ABCDE's of skin cancer she would have recognized that the mole was asymmetric, the borders were jagged and it was beginning to show different colors throughout. The diameter was larger and it was evolving into something that it did not look like before.
3. Should Judy be concerned? Why or why not? (2 points)
Judy should definitely be concerned. Her mole was showing most of the signs and characteristics of melanoma.
Part II—"The Basics of Cancer" Questions
1. Considering the differences between a benign tumor and a malignant tumor, why might a benign tumor be easier to treat? (3 points)
A benign tumor is easier to treat because...
