Beata Halasi, a virologist at the University of Zagreb, attempted a bold and unconventional approach by using virus-based therapy on herself to treat her recurring breast cancer. With the permission of her oncologists, she injected viruses grown in her lab directly into the tumor, leading to its shrinkage and eventual surgical removal. Despite being cancer-free for 45 months following the treatment, her decision to self-experiment has sparked discussions in the medical community about the ethics and implications of such innovative approaches.
