  schema:description "Hepatitis B can lie quiet for decades and flare when cancer treatment weakens the immune system, sometimes fatally. An American Society of Clinical Oncology opinion says everyone starting systemic cancer treatment should be tested first, and antiviral tablets prevent most flares. Across 29 studies, 57 per cent of patients were tested before chemotherapy."@en ;
