What is Leukemia?

What is Leukemia?

Today, one of the most dangerous and incurable condition seems to be cancer. It has no actual cure for mostly of the tissues it affects, especially when it reaches vital organs such as heart, lungs or blood. The blood tissue form of cancer is known as Leukemia and it represents a real life threat as it affects the blood circulation meant to supply the whole body with vital nutriments.

Blood is the connection tissue for all of the body's organs and tissue as it carries oxygen and other important elements for the cell life. This is the reason why leukemia is such dangerous and frightening disease. Blood has access to all vital organs like heart, lungs and brain and when Leukemia occurs, it will rapidly create a dysfunction of all the other organs by supplying them with unhealthy particles. Cancerous cells are quickly carried to all parts of the organism and the dissemination occurs in a very short period of time.

What is Leukemia ?
Leukemia is in fact the consequence of an abnormality occurred in the form and number of leukocytes, the blood white cells. Leucocytes are vital for the good functioning of the body as they have the role to fight against all potential aggressions from the outside. They are the key to a good protection against infections and when leukemia appears the cellular immunity decreases drastically leaving the body unable to protect against damaging factors of any nature.

The main pathological way of the disease is an increased production by the marrow of infected and abnormal white blood cells. The new leucocytes anatomically and functionally modified and interfere with all functions of the blood even hindering the normal oxygen transport. Modified white blood cells also damage the normal functioning of the red blood cells and lead to the occurrence of anemia. Cancerous cells impede the tissue supply with hemoglobin and the body cells suffer from the lack of iron.

When the cancerous cells reach the brain, other dangerous modifications appear such as headaches, night sweats and neuropsychical problems. Cancerous Leukemia cells can be easily detected under the microscope and the suspects of the disease are advised to undergo a bone marrow examination. The onset of Leukemia is pointed out by swollen lymph nodes through the whole body, especially around the neck and thigh.

What is Leukemia ?
Risk factors for Leukemia are especially radioactive radiations that produce cell mutations and damages to their activity. An overexposure to benzene, an industrial hydrocarbure, also increases the risk of developing Leukemia, as well as the Down syndrome.

The most effective but also painful treatment is chemotherapy when the patients need to swallow many drugs at once. Another possibility of treatment is radiotherapy and patients suffer from losing hair and skin texture.

Leukemia is curable if detected in time and treated right. A bone marrow transplant may be helpful to regain healthy white blood cells. For a good outcome, the patients especially need the support of the family.
