Leukemia Symptoms | CAUSES OF LEUKEMIA | Acute Myeloid Leukemia
Leukemia : In this tutorial on leukemia,we explain extensively on;
- Leukemia Symptoms
- CAUSES OF LEUKEMIA
- Acute Myeloid Leukemia
Leukemia is generally referred to as cancer of the blood cells. It starts mostly in the bone marrow; that is the soft tissue right inside most bones. The bone marrow is the site where blood cells are formed.
When the bone marrow is healthy, it produces;
White blood cells; which help the body fight infections.
Red blood cells; Helps to carry oxygen to all parts of the body.
Platelets; Plays a role in bloodclotting.
When we say an individual hasleukemia, it simply that the bone marrow starts to make a lot of abnormal white blood cells, excess of it called leukemic cells.
These abnormal white blood cells do not do the work of normal white blood cells, rather they grow faster than normal cells, and they donot stop growing when they shouldbut rather they end up causing leukemia symptoms and reactions Like Anemia, bleeding, lymph nodes, swelling or pains.
Overtime,leukemia cells can crowd out the normal blood cells. They can lead to serious problems such as anemia, bleeding and infections. Leukemia cells can also spread to the lymphnodes or other organs and cause swelling or pain.
There are several different types of leukemia. In general, leukemia is grouped by how fast it gets worse and what kind of white blood cell it affects. It may be acute or chronic. Acute leukemia gets worse very fast and may make the individual feel sick right away.
Chronic leukemia gets worse slowly and may not cause symptoms for years.
It may be lymphocytic or myelogenous. Lymphocytic (or lymphoblastic) leukemia affects white blood cells called lymphocytes. Myelogenous leukemia affects white cells called myelocyte.
Therefore leukemias are a group of disease characterised by increased numbers of white blood cells in the blood and bone marrow (Hoffbrand et al., 2006).
Types Of Leukemia Disease
The four main types of leukemia are:
- Acute lymphoblastic leukemia or ALL
- Acute myeloid leukemia or AML
- Chronic lymphocytic leukemia or CLL
- Chronic myeloid leukemia or CML
In adults, chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML) are the most common leukemias. In children, the most common leukemia is acute lymphoblastic leukemia (ALL). Childhood leukemia also include acute myelogenous (myeloid) leukemia (AML) and other myeloid leukemia, such as chronic juvenile myelomonocytic leukemia (JMML).
There are less common leukemias, such as hairy cell leukemia. There are also subtypesof leukemia such as acute promyelocytic leukemia (a subtype of AML).
CAUSES OF LEUKEMIA DISEASE
Experts donot know what causes leukemia. But some things are known to increase the risk of some kinds of leukemia. These things are called Risk Factors. People are more likely to get leukemia if they:
- Were exposed to large amounts of radiation
- Were exposed to certain chemicals at work such as benzene
- Had some types of chemotherapy to treat another type of cancer
- Have Down syndrome or some other genetic problems
But most people who have these risk factors donot suffer leukemia. And most people who suffer leukemia do not have any known risk factor.
Leukemia Symptoms| Leukemia Symptoms In Adults | Symptoms Of Leukemia
Symptoms of leukemia may depend on what type of leukemia an individual has. The can be Leukemia Symptoms In Adults, symptoms of leukemia in children and acute leukemia symptoms but common symptoms include:
- Fever and night sweats
