Case Study 1 Integumentary Questions

Module 02 Case Study: Integumentary System

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)

The first major difference between Judy and Mariah is their complexion. Unfortunately, I know all too well that the fairer your skin is, the more likely you are to develop skin cancer. Genetics also play a major role; the two girls obviously have different genetics.

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 the mole had grown, the edges had become jagged, one edge was darker, and that there was now a raised purplish-black dot in the center. ABCDE’s of melanoma according to skincancer.org are as follows: asymmetry, border, color, diameter, and evolving. By those standards, the girls could have assessed almost instantly that the “mole” was most likely malignant.

3. Should Judy be concerned? Why or why not? (2 points)

Yes, Judy should be concerned. Melanoma is a very serious form of cancer. A simple biopsy can determine whether the mole is benign or is in fact malignant.

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 would be easier to treat because it will not spread to other parts of the body, whereas malignant tumors will metastasize if gone untreated.

2. Judy learned that every single person has these cell cycle genes so cells in our body can divide when necessary. What are some normal circumstances where our bodies might need to make more cells? Why is the skin continuously replacing its main cell and what specific damages to the skin would there be a need to make more cells? (3 points)

Hair and skin cells are being replaced on a daily basis...
