Leukemia; Facts, Symptoms, Causes and Preventions

0 50

Leukemia can be defined as the cancer of the blood cells, especially the white blood cells. Also, the white blood cells produced are in the bone marrow, helping to fight the body against infections. It also leads to the abnormal and uncontrolled production of white blood cells.

Leukemia is a malignancy of blood cells. In this malignancy, abnormal blood cells are produced in the bone marrow. However, it involves the production of abnormal white blood cells – the cells responsible for controlling infection.

However, the abnormal cells in leukemia malfunction in the same way as healthy white blood cells. Moreover, the leukemacelles continue to grow and divide, which ultimately rinses the normal blood cells. Though the results are that it is difficult for the body to fight infections, check blood and transport oxygen.


Although it is one of the most common cancers, however, it also occurs more often in adults, usually in men than women. It is unlike other cancers; it is not a stable tumor. Many people who get leukemia have no known risk factors.


The exact cause of leukemia is unknown. However, some risk factors and environmental factors have shown that the risk of people who have leukemia is increasing.

Leukemia can be classified by how quickly the disease develops (acute or chronic). Also, it could be grouped as the type of blood cell that is affected (lymphocytes or myelocytes). It could also be divided into four major categories which include;

Acute lymphocytic

Cute myelocytic

Chronic lymphocytic

Chronic Myelocytic

Those people affected with leukemia have a significantly increased risk of developing infections, anemia, and bleeding. Other symptoms and signs also include easy bruises, weight loss, night sweats and unexplained fever.


According to the National Cancer Institute, the prevention of this disease is yet to be known, but life expectancy can increase if the risk factors are reduced.

The earlier leukemia is diagnosed and the faster it is treated, the better the chance of recovery as well.
