Leukemia is also known as blood cancer. However, this term is a misnomer because rather than causing cancer in the blood, the cancer is caused in the bone marrow and it affects the white blood cells. These cells are responsible for fighting infections, bacteria and viruses that enter our body. Once the white blood cells are affected, our body gets weakened and is exposed to infections.
There are several types of leukemia and the treatment varies depending on the type. However, the two main types of leukemia are acute leukemia and chronic leukemia. Chronic leukemia is considered to be milder; in other words not all the white blood cells are defective and the progress of the disease is much slower than acute leukemia.
Acute leukemia advances rapidly and all the white blood cells are not normal. However, in some cases it is easier to treat than chronic leukemia.
In the United States, each year thousands of people are diagnosed with acute leukemia. However, it has been seen that a large number of children, mostly around 4 years old, are afflicted more frequently by acute leukemia. The good news is that more and more cases are being cured and there is constant research for new medication and treatment methods.
The cause of acute leukemia is unknown. The only thing that one can say for certain is that some people are at a higher risk of getting the disease than others. People who are exposed to radiations or certain chemicals have the highest chance of contracting the disease. In addition, there is the hereditary factor. It has been seen that children receive the defective gene from their mother and this gene may lead to acute leukemia.
People who have leukemia tend to bruise easily or bleed easily from the nose and gums. In addition to weak immune system, there is a general feeling of fatigue and unexplained weight loss. The disease by itself does not have any specific symptoms.
