Gene Mutation: A Lifetime Risk of Stomach Cancer
27 Apr
Summary
- CDH1 gene mutations carry a 70% lifetime risk of diffuse gastric cancer.
- Māori families are disproportionately affected by this rare cancer.
- Individuals face a choice between high cancer risk or stomach removal surgery.
Individuals carrying certain mutations on the CDH1 gene face a daunting 70 percent lifetime risk of developing diffuse gastric cancer. This rare and aggressive form of stomach cancer has been observed to cluster within families, notably among Māori communities, as highlighted by Karyn Paringatai's personal experience with her family history.
The hereditary nature of this cancer means that individuals often learn about a tragic pattern of early deaths within their relatives. This genetic link prompts a profound and challenging decision for those identified with the mutation.
They must weigh the considerable risk of succumbing to diffuse gastric cancer against the drastic measure of undergoing a total gastrectomy, the surgical removal of the entire stomach. This difficult choice underscores the severe implications of these specific gene mutations.
