Rogelio Mayuga, 45 years old, was unfortunately diagnosed with malignant neuroendocrine carcinoma. After surgical removal in January 2025, the tumor recurred. The massive facial tumor severely impacted his speech and swallowing functions, and even caused hearing loss. Following treatment at Modern Cancer Hospital Guangzhou, after just one session of seed implantation, the tumor visibly reduced. After three treatment courses, the lesion has significantly shrunk, his facial contours have been restored, and his various functions have largely returned to normal.
