Leukemia is a cancer which arises in the bone marrow leading to an overproduction of the abnormal white blood cells. White blood cells are required to maintain the immunity of the body. When these cells become poorly developed and abnormal, one has an increased risk of infections. There are 4 types of leukemia which are described below.Myeloid
Acute types of leukemia are characterized by a rapid increase of immature blood cells. Whereas, chronic types of leukemia are characterized by a slower growth of mature blood cells. Myeloid type of leukemia originates from the blood cells which develop as white blood cells (except for lymphocytes and other blood cells such as red blood cells). Lymphocytic type of leukemia arises from the blood cells called lymphocytes (a type of white blood cells T cells or B cells).
Acute myeloid leukemia can be explained as the rapid increase of immature cells which are going to develop as white blood cells or other red blood cells. It is a common type of leukemia; which can spread quickly to the blood and other parts of the body such as lymph nodes, liver, spleen, brain and spinal cord.
Most of the cases of leukemia don’t have any obvious cause. However research states that it develops from a combination of genetic and environmental factors. Some of the causes are given below:
Physical signs of leukemia are common to most of the leukemia types. Therefore specific laboratory tests are needed for an accurate diagnosis of leukemia. Some of the common signs of leukemia and symptoms are given below.
There are eight stages of acute myeloid leukemia. Those stages are explained below. Survival rate and the treatment type may change according to the stage.
Acute myeloid leukemia can affect both children and adults; however, it is commonly seen in adults. Even though a 5 years survival rate of acute myeloid leukemia is 26%, life expectancy can be enhanced with effective and accurate treatment. Patients younger than 60 years of age respond well to treatment and 70% to 80% of them go into remission stage of their cancer after the effective treatments.
