  schema:description "About eight in ten Merkel cell carcinomas are driven by a common skin virus that has stitched itself into the tumour's DNA; the virus-negative rest are driven by sunlight and carry a huge mutation load. Both respond to immunotherapy, and in virus-positive patients a blood antibody test against the viral protein can track the cancer after treatment."@en ;
