Leukemia is a broad term covering a spectrum of diseases and clinically and pathologically split into its acute and chronic forms.
Acute leukemia is characterized by the rapid proliferation of immature blood cells. This crowding makes the bone marrow unable to produce healthy blood cells. Acute forms of leukemia can occur in children and young adults. (In fact, it is a more common cause of death for children in the US than any other type of malignant disease). Immediate treatment is required in acute leukemias due to the rapid progression and accumulation of the malignant cells, which then spill over into the bloodstream and spread to other organs of the body. However, CNS involvement is uncommon, though the disease occasionally causes cranial nerve palsies.
Chronic leukemia is distinguished by the excessive build up of relatively mature, but still abnormal, blood cells. Typically taking months to years to progress, the cells are produced at a much higher rate than normal cells, resulting in many abnormal white blood cells in the blood. Chronic leukemia mostly occurs in older people, but can theoretically occur in any age group. Whereas acute leukemia must be treated immediately, chronic forms are sometimes monitored for some time before treatment to ensure maximum effectiveness of therapy.
Furthermore, the diseases are classified according to the type of abnormal cell found most in the blood or bone marrow (lymphoid cells vs. myeloid cells).
Combining these two classifications provides a total of four main categories:
Lymphocytic leukemia Acute lymphocytic leukemia (also known as Acute Lymphoblastic Leukemia, or ALL) is the most common type of leukemia in young children. This disease also affects adults, especially those age 65 and older.
Chronic lymphocytic leukemia (CLL) most often affects adults over the age of 55. It sometimes occurs in younger adults, but it almost never affects children.
Myelogenous leukemia (or "myeloid") Acute myelogenous leukemia (AML) (also known as Acute Myeloid Leukemia, or AML) occurs more commonly in adults than in children. This type of leukemia was previously called "acute nonlymphocytic leukemia".
Chronic myelogenous leukemia (CML) occurs mainly in adults. A very small number of children also develop this disease.

Once a diagnosis of leukemia has been made, further tests are performed to assess the following properties whether the cells are myeloid or lymphocytic (i.e. the cell of origin).
- Stage of maturity of the ALL B-cell.
- Their immunologic features (the specific markers on the surface of the cancer cell that respond to antigens).
- Their cytogenetics (the genetic makeup of the cells).
- Their morphology (their physical characteristics).

Ramri I am not involved in this activity nor I know her, just your queries tempted me to highlight few things thats all. I just gave the overview about leukemia. May be someone who is close to her and working for this fund rising event, can tell the prognosis.
Its a good job, lets support their fund rising activity.
