Mary has a brain tumour - CLIC Sargent

One day Mary saw a boy called Joe come to the ward whowas not allowed to play with anyone. She was told that hehad come for some medicine to help stop him catchingchickenpox from his friend at school who had woken upone morning with spots all over his body. People who arehaving chemotherapy can be very unwell if they catchchickenpox, or other bugs. Mary thought it strange thatyou could catch chickenpox but that you couldnot catch cancer.People having chemotherapy can alsobecome unwell if they get infections in theirbloodstream, which is why Mary’s mum tookher temperature quite often.23
