Problem 5. A patient’s skin tumor is surgically removed and it is determined that the patient does not have any other tumors. Did the patients skin cells undergo metastasis? Why?

Problem 6. A cell has a mutation in a gene which allows it to bypass apoptosis. Why is the cell more likely to develop into cancer?

If the cell does not gain any additional mutations, will it develop into cancer? Why?
