  schema:description "Hepatitis B can sleep in the liver for years and wake up when cancer treatment weakens the immune system, sometimes damaging the liver badly. A blood test before treatment finds people at risk. Those who have it, or have had it and get high-risk treatment such as rituximab or a stem cell transplant, take an antiviral tablet during and for at least a year after treatment, or are checked closely."@en ;
