Open Question

A tumor is a growing mass of abnormal cells.Describe the difference between a benign tumor and a malignant tumor.

Open Question

For the retinal cancer retinoblastoma, the inheritance of one mutated copy of RB1 from one of the parents is often referred to as a mutation that produces a 'dominant predisposition to cancer.' This means that the first mutation does not produce cancer but makes it very likely that cancer will develop.Define the 'two-hit hypothesis' for retinoblastoma.

Open Question

Where are the major regulatory points in the cell cycle?

Open Question

What is the difference between saying that cancer is inherited and saying that the predisposition to cancer is inherited?

Open Question

As a genetic counselor, you are asked to assess the risk for a couple with a family history of familial adenomatous polyposis (FAP) who are thinking about having children. Neither the husband nor the wife has colorectal cancer, but the husband has a sister with FAP. What is the probability that this couple will have a child with FAP? Are there any tests that you could recommend to help in this assessment?
