Vivian Walters went in for what she thought would be a routine hysterectomy with Dr. Harry Johnson at UMMC. During surgery, Dr. Johnson discovered an issue with her appendix, and a biopsy later confirmed a rare appendiceal tumor, a diagnosis found in fewer than six people per million.
Vivian was quickly connected with gastrointestinal cancer expert Dr. Benjamin Powers, surgical oncologist, and UMGCCC’s expert care team. After thorough testing, Vivian and Dr. Powers created a treatment plan for her low-grade appendiceal mucinous neoplasm (LAMN), which had spread to the lining of her abdomen.
Vivian later underwent an 11-hour CRS-HIPEC procedure to remove the disease, and she has since made steady progress in her recovery. Dr. Powers emphasizes that Vivian’s journey highlights the importance of early detection and coordinated, compassionate care.
