Childhood Leukemia

I have a 16-mos. old grand-daughter.  Since approximately Nov. 2007, she had a cold, fever, cough.  My daughter was consistent in taking her to doctor visits and ER visits because she was not getting better.  
On doctor visits, she was told she had a nasal virus, on another visit she was told she had a throat virus.  One time I took her to a doctor appt. and was told she still had a virus and she would get over it.  I asked the doctor to do a chest x-ray because her breathing wasn't normal.  At first, the doctor didn't want to, but I persisted and said my daughter had requested one be done.  The doctor complied.  Later that evening, there was something abnormal with x-ray.  On one of the visits, doctor/nurse tried to draw blood, but because she couldn't find a vein, was told that maybe next time the would draw blood out.  One of the next visits, same thing happened.
Last week the baby was taken to a doctor visit, still said she had a virus.  Next day, Tues., she was taken to the ER and the doctor told my daughter that she could have taken her to her primary doctor  instead of taking her to the ER and the doctor refused to draw blood out.  My daughter made an appt. to see primary and ask for a complete physical.  The receptionist told her that she could only make an appt. for a follow-up and not for a physical.  My daughter requested to speak to the doctor, but instead was transferred to the office manager.  Office manager with my daughter's permission to look into the medical file, said she would see what she could do.  Anyways, the baby went to the doctor Thursday (seen by a new doctor because the previous one had been transferred).  Blood was drawn and later that day at 9p.m., the doctor called to take the baby to the ER - ASAP because her blood lever was extremely low.  She had to have blood transfusions.  At 11:00 p.m., she was diagnosed with leukemia.  A bone marrow and spinal tap were done.  She does not have the usual children's leukemia.  Still waiting on result from bone marrow, was sent out for further analysis.  
My question:  With all the doctor visits and follow-up appts. shouldn't something have been done sooner and if so, wouldn't she have been treated with medication instead of this illness progressing and the initial treatment have been so extreme?  Thanks you for listening and for your input.
