Imagine your own child to have been diagnosed with cancer and having to undergo a treatment of chemotherapy for 3 years. Not only that, but also having to deal with enormous physical and mental suffering, like loosing your hair, pain, nausea, vomiting, fear of death and many others. The socio-economic and mental burden on the patient and their families is great. However, the good news is that the most common childhood cancers like Acute Lymphoblastic Leukaemia, a type of blood cancer, have survival rates of about 80-90% nowadays in developed countries.
