This assignment is created in Word. It includes a graph with 5, 10, 15 and 20 year survival rates for 24 different cancers. There are approximately 10 questions in the assignment directly related to the graph - no other material is needed to answer the questions on this worksheet. I go over the different survival rates with the class before I let them complete the assignment. We talk about 'metastasis', 'malignant/benign', and why the 20-year survival rate is often very different from the 5-year survival rate. A general knowledge of cancer and metastasis by the teacher may be helpful for this discussion. The KEY is included.
