To most people, an inheritance is something they are given when a relative dies – property, money or something sentimental. The word now has a very different meaning to the Harmon family. A genetic mutation, known as BRCA 1, has been silently passed from generation to generation, from parent to child. Only discovered its presence in their family three years ago. It means that those who inherit this faulty gene will have a much higher risk for breast and ovarian cancers. It was first detected when Nancy was diagnosed with breast cancer for a third time. Soon after, her sister, Janne mustered the strength to take the test. Knowledge is power, but it can also be frightening. She, too, had inherited the genetic mutation. The presence of BRCA 1 in the Harmon family has unleashed a wide range of disruption, emotions and life choices. Do they “wait and watch” through surveillance or launch a pre-emptive strike with radical surgery? What about the grandchildren in the family? Should they be tested? I’ve been photographing the Harmon family as they wrestle with these questions and embark on this unplanned journey.
