  schema:description "Cancer registries were never built to count a cancer that people get several of. Britain's registries long recorded only the first basal cell carcinoma and the first squamous cell carcinoma in a person's lifetime, and the headline 'cancer in the UK' figure leaves these cancers out altogether. Every number on these pages is a floor, not a count."@en ;
