In general, ALL is diagnosed with a bone marrow test, in which a small amount of bone marrow is taken from the hipbone with a thin needle to look for signs of cancer. Blood tests will also be taken to track the changes in the number of blood cells and to help diagnose the specific type of leukemia. In most ALL patients, there are too many white blood cells and not enough red blood cells or platelets.
What is Treatment Like?
In most cases of ALL, chemotherapy is the primary treatment option. Chemotherapy works by killing all rapidly dividing cells, which is the main characteristic of cancer cells. Since ALL tends to spread aggressively, treating this cancer usually requires the use of several types of chemotherapeutic drugs over a long period of time to be certain that all of the cancer cells are killed.
Because chemotherapy kills any rapidly-dividing cells, not specifically cancer cells, and spreads throughout the body, there are many side effects to this treatment, including hair loss, mouth sores, infection, bruising, tiredness, nausea, loss of appetite and vomiting. There are ways that doctors can help minimize the impact of these side effects and they tend to go away when treatment ends.
There are also some newer methods currently being testing for their effectiveness on ALL. These include drugs that more specifically target cancer cells and also stem cell transplantation that helps the body to regenerate new bone marrow after high doses of chemotherapy.
What if the Cancer Returns?
Once beaten, ALL may return, referred to as cancer recurrence. If this happens, doctors will likely recommend treatment to try to beat the cancer once again. Unfortunately, if ALL returns once after chemotherapy, it is likely that it will keep returning. Therefore, the American Cancer Society suggests trying a stem cell transplant or other experimental drug to try to beat the cancer in a different way.
If there aren't any other options for trying to treat ALL, doctors often shift their focus to trying to control the cancer's spread and alleviating some of the side-effects of living with cancer, including loss of appetite and depression.
Fortunately, most of the time, once ALL goes into remission, it will not return. In fact, the National Cancer Institute estimates that as many as 85 percent of children with ALL survive free of cancer for at least five years, at which point the cancer is considered to have been cured.
