Leukemia is a dangerous form of cancer, and it affects thousands of people every year. It affects the white blood cells. The body loses control of the quantity and quality of blood cells, and it becomes very vulnerable because the white blood cells are supposed to protect our organism against infections. There are two main types of leukemia - acute leukemia and chronic leukemia. Acute leukemia is more dangerous because it spreads much faster, but chronic leukemia can be tricky because it has almost no symptoms.

The first organ that is affected by chronic leukemia is the bone marrow. The bone marrow is a tissue that can be found on some of the main bones in the body and that has the role of producing blood cells (red blood cells and white blood cells).

White blood cells are the guardians of the body. They can be found anywhere in the blood and they attack and neutralize any type of bacteria that enters the body and that can be harmful.

When a patient has chronic leukemia, the white blood cells from his blood are deffective and they are continuously created. A normal person should have less then 10000 white blood cells white a person with leukemia can have more than 100000, but although there are so many the protection against infections is decreased because most of the cells are malfunctioning.

A particularity of chronic leukemia is that patients who have it also have a lower number of red blood cells.

The causes of all types of leukemia are unknown, doctors cannot determine why some people have this illness and other don't. Though, scientists discovered some factors that increase the risks of becoming ill of leukemia. Among these factors radiations play an important role, many that were exposed to radiations were soon diagnosed with leukemia. Also, a malfunction in the genes can cause the blood cells to transform, so it can have a genetic cause. The causes and risk factors are still being researched.

The bad thing about chronic leukemia is that it usually shows no symptoms that can give he patient an idea about his condition. It's often discovered during routine lab tests. Some of those suffering from chronic leukemia reported having a general state of weakness and fatigue. As the disease advances blood can start to come out of the nose or of the gums for no reason, and because the organism is weakened and its defense is lowered, leukemia patients can be vruised very easy, and they are often infected with foreign microorganism.

Chronic leukemia treatment depends on each patient. After the diagnose a series of tests are made to determine which therapy the patient responds to. Chemotherapy is used in most situations. The number of people that are cured of chronic leukemia is increasing as time passes, but a there is a notable number of victims too.

New drugs and cures keep being researched by doctors and scientists and the survival rate is rising, so maybe in the near future chronic leukemia will be musc easier to treat.
