Any tumor that arises from new, abnormal cell growth.
What are the two ways that cancer spreads?
1. Invasion- in which cells grow in unrestriced disorderly fashion at the site of origin.
2. Metastasis- in which the cells grow in sites other thatn the site of primary cancer.
What is tumor staging?
the extent of disease locally, regionally , and systemically and guides the therapy for most solid tumors.

What is leukemia?
THe most common type of cancer in kids under 15 years. The cause of disease is an abnormal proliferation of immature WBC's which compete with normal cell for space and nutrients. Bone marrow is suppressed so very low numbers of RBC's and platlets may be seen in diagnosis.

A lumbar puncture can also be preformed to look for leukemic blast cell in the spinal fluid which are indicative of CNS involvement.
What is the goal of the first phase of chemo for leukemia?
Induction (to induce remission)
As WBC's break down from chemo what happens?
They release Uric acid and can compramise the kidney function leading to (tumor lysis syndrome)
What does a more than 5% of blast in the marrow on the 28th day of treatment indicate?
