What is a notable risk factor for breast cancer in Peutz-Jeghers Syndrome?

Peutz-Jeghers Syndrome, an autosomal dominant genetic condition caused by mutations in the STK11 gene, significantly increases the risk of several cancers, including breast cancer. Individuals with Peutz-Jeghers Syndrome are estimated to have a nearly 100% risk of developing breast cancer by the age of 60. This high predisposition is attributed to the underlying genetic factors associated with the syndrome, which include not only breast cancer but also gastrointestinal and other malignancies.

This nearly universal risk underscores the importance of vigilant surveillance and management strategies for individuals diagnosed with Peutz-Jeghers Syndrome. Such high-risk assessments are crucial for early detection and intervention, which can improve outcomes in affected individuals. The other options do not accurately reflect the extent of risk observed in studies related to this syndrome, emphasizing the significant concern clinicians have regarding management and risk-reduction strategies for these patients.
