Imagine immune cells that only wake up to fight cancer when zapped by ultrasound—and then keep going for days!

Fewer hospital visits, more precise attacks, and a real shot at beating tough cancers. This could totally change the game for cancer treatment! #CancerBreakthrough #Immunotherapy #MedicalInnovation #USCResearch #HealthNews #Health
