Pre-Empting a Diagnosis

If a parent suffered with terminal cancer and you were most likely going to suffer the same fate, what would you do to avoid the same health diagnosis?
 
After watching her mother die of ovarian cancer, after previously suffering through breast cancer, Jessica Quellar decided to see if she had the gene that would lead to both of these diseases. She does. Worried that she was headed for a life of sickness and chemo, Quellar decided to have both breasts removed at 35 and will have her ovaries removed by the time she reaches 40.
 
If you're curious about what would drive someone to take such drastic measures, you can read about her experience in her memoir, Pretty is What Changes: Impossible Choices, The Breast Cancer Gene, and How I Defied My Destiny. Quellar says she feels like her mom’s illness was a sign for her to change the course of her health.
