I have a child who was treated for ALL. As I researching the history of it I felt I was living in the time of Science Fiction. A generation or two before there was no treatment and with my child they were doing very specific genetic tests to tune chemo treatment levels to his specific version of ALL. We spent a couple of months in the paediatric oncology ward, 70% of his cohort (mixed cancers) in the ward did not survive his 3 year treatment cycle. My sister-in-law had stage 4 melanoma with 6 months or less prognosis. She was entered into an immunotherapy trial. 8 years later she is great. However, she was the only one out of 6 who survived in her trial. I don’t know all the details but all others withdrew - it was not a fun ride. It is truly an amazing time.
