BRCA1 and peritoneal carcinoma: Testing decisions should be individualized based on family history, patient preferences, and reproductive goals, as demonstrated in our case, where the patient prioritized fertility preservation over genetic risk assessment. While the patient declined genetic testing, it must be noted that studies on isolated STIC demonstrate that the subsequent development of peritoneal carcinoma is almost exclusively observed in BRCA1 carriers [8]. Therefore, her decision introduced a necessary, yet calculated, long-term risk of relying solely on surveillance while actively pursuing fertility treatment.
