In 2016, virologist Beata Halassy was diagnosed with invasive triple-negative breast cancer (multiple foci). Treatment involved mastectomy of the left breast plus adjuvant chemotherapy. In 2020, she found that her breast cancer had come back for the second time in the same place. The tumour had grown into nearby tissue and was considered advanced. She did not want more chemotherapy. Unwilling to undergo further chemotherapy, she prepared research-grade measles vaccine strain and vesicular stomatitis virus in her laboratory. A colleague injected these viruses directly into the tumour over two months under oncologist supervision. The tumour shrank a lot and became easier to remove. Doctors then took it out with surgery, and she took trastuzumab ( cancer drug) for one year. She has stayed cancer-free for more than four and a half years. This was a careful one-person experiment not a standard treatment for others. Her successful self-treatment completely changed the direction of her laboratory. She is now focused on oncolytic virotherapy (using viruses to fight cancer) research.
