Over the past two months, I have become worried that my 4 year old son has leukemia. I tend to worry more than necessary but he has multiple bruises on his legs, has had one or two small bruises on his trunk, is pale and has had two ear infections and two URIs since early May. His weight is stable, he is not unusually fatigued and has no enlarged lymph nodes.   I have had him at the pediatrician several times for the URIs and ear infections so he has had physical exams but should I push for blood work?  Would it be obvious if he had leukemia?

Thanks in advance.

Hi, Brooke,

I'm not a big believer in labs for kids, but when a mother asks me about leukemia and her kids has vague symptoms, I usually just do a CBC with differential count.  Easy to do and pretty definitive evidence that a child, hopefully, doesn't have it.  Ask your doctor about this.

Good luck, Dr. Olson

I would be happy to attempt to answer any questions about general pediatric topics, either medical issues or behavioral issues. This would include all the various questions one receives in a busy pediatric practice. I`m a board certified pediatrician in northern Michigan and have been in practice for over 15 years. I enjoy the teaching role I have in our practice and would enjoy the opportunity to help others with their pediatric problems.
