If you read it on the internet, it must be true!
Blood cancer is actually a complex family of five diseases, each with its own subtypes. But, because they all affect how our bodies produce and use blood, doctors group them together as a distinct class of cancers.
Leukemia
Lymphoma
Myelodysplastic Syndromes (MDS)
Myeloproliferative Disorder (MPD)
Multiple Myeloma
