Welcome to Mayo Connect, @jammy17. While there is no definitive proof yet, there are studies underway that have led to a possible correlation of Lyme's disease and some blood cancers, especially CLL (Chronic lymphocytic lymphoma). While Lyme disease itself does not directly cause cancer, chronic inflammation associated with it may elevate cancer risk. So perhaps down the road there will be more discoveries on how this tiny bug can wreak so much havoc to our body in causing other blood cancers such as myelofibrosis. (MF)

Twenty years ago there wasn't much information on Lyme disease. Were you able to be treated right away with Doxycycline or did it take a while for your doctors to diagnose the Lyme's disease?
Are you in a treatment program for your MF?
