In certain cases, genetic testing can identify mutant alleles that greatly increase a person’s chance of developing a disease such as breast cancer or colon cancer. Between 50 and 70% of people with these particular mutations will develop cancer, but the rest will not. Imagine you are either a 30-year-old woman with a family history of breast cancer or a 30-year-old man with a family history of colon cancer (choose one). Each person can undergo genetic testing to identify a mutation that greatly increases susceptibility to the disease. Putting yourself in the place of the person you have chosen, provide answers to the following questions.
a. If you have a spouse or partner, are you obligated to tell that person the result of the genetic test? Why or why not?
b. If you have children, are you obligated to tell the children the result of the genetic test? Why or why not?
c. If you were the spouse or partner of the person you have selected, would you encourage or would you discourage the person from having the genetic test? Why?
d. If this person that you have selected were you, do you think you would have the genetic test or not? Can you explain the reasons for your answer?
