SINGAPORE - When Caleb Lee was in Secondary 2 in 2018, he woke up one morning to jolts of pain in his thighs that were so excruciating that his mother had to take him to a polyclinic. He was referred to KK Women's and Children's Hospital that same day, where he was diagnosed with acute lymphoblastic leukaemia, a type of cancer. The St Hilda's Secondary School student told The Straits Times: "Everything went downhill so fast and I was warded immediately. When the doctor told my mother (the diagnosis), she came out of his office crying." "I thought 'What did I do to deserve this?'. I was also crestfallen because there was not much I could do to change my condition."
