Pope Leo Cancer Update; Hep B Vaccine Trial Halted; 'Dark Nutrition' Trend
Pope Leo XIV, 71, will not require further medical treatment for lung cancer after surgery to remove the lower lobe of his right lung last week. Vatican officials and medical staff confirmed on Wednesday that histological and molecular tests on the removed tissue showed the adenocarcinoma was localized and had not spread. The Pope was discharged from the hospital on Saturday, ahead of schedule, and has begun resuming his duties, including his weekly audience. While his recovery is progressing, uncertainty remains regarding his scheduled trip to South America in November.
