integumentary system case study
1. What are some differences between Judy and Mariah that might make Judy more "at risk" for skin cancer than Mariah? (2 points)
Judy was pale, had red hair, did not normally tan. Mariah tanned every summer, had dark hair.
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) She observed it was bigger and the edges were more jagged than she remembered. One edge was darker than the other and there was a purplish –black dot in the middle. A:asymmetry: the mole is not asymmetrical. B:border: the border is not even. C: color: she has multiple colors. D:diameter:the mole seems to have grown. E:evolving: the mole has changed.
3. Should Judy be concerned? Why or why not? (2 points) Her mole has changed in several ways: color, size, border, and those changes should have her going to the doctor and have her concerned.
4. Considering the differences between a benign tumor and a malignant tumor, why might a benign tumor be easier to treat? (3 points) Cells in benign tumors do not spread to other parts of the body. Malignant tumors are cancerous and are made up of cells that grow out of control. Cells in these tumors can invade nearby tissues and spread to other parts of the body.
5. 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) Normal circumstances in which we need to make more cells would be body growth, or daily living. Our body is constantly migrating cells from the lowest layer to the superficial layer where our skin is replaced every 4 weeks or so. We need skin cells constantly made to replace our outer layer. A specific damage would be a burn, any burn in
