Question: What is the difference between acute and chronic leukemia?
Answer: Acute and chronic leukemia are two different classifications of the disease.

In chronic leukemia, the leukemia cells come from mature, abnormal cells. The cells thrive for too long and accumulate.The cells grow slowly.

Acute leukemia,on the other hand, develop from early cells, called "blasts". Blasts are young cells, that divide frequently. In acute leukemia cells, they don't stop dividing like their normal counterparts do.
