My children were both 4 years of age when they were diagnosed with Acute Lymphoblastic Leukaemia. And by the way, they're not twins.
Their prognosis was very grave and the doctor said they'd be lucky to survive. I'm going back to the early 70s here.
After massive amounts of chemotherapy and radiation treatment to the brain for a period of 3 years, they both went into remission. It has been an incredible journey for us as a family, as there was no support for any of us in those days, however we managed to get by and last Saturday, my daughter turned 40 and today, 4th. March, 2010 is my son's birthday and he's 37.
They're 2 very lovely adults and I'm so proud of them as they're both in the work force with excellent careers.
The Leukaemia in all these years never returned, however my son 4 years ago had a brain tumour removed (a 'late effect' of the chemo and radiation therapy so long ago) and now my daughter has been diagnosed with one.
As you can see it has been a long journey and is not over yet.
