Leukemia is defined as a condition of abnormal growth of white blood cells produced by bone marrow and / or lymphatic system. Depending on the malignant lymphocytes or granulocytes, leukemia can be divided into myeloid or lymphoblastic leukemia.
Bone marrow is the soft tissue inside the hollow center of large bones. including the spine, pelvis, under the arms and legs. etc.
types of leukemia
Leukemia can be classified into two types
A. Acute leukemia
Acute leukemia is defined as a state of rapid increase in the number of extreme immature white blood cells that appear in the blood to other parts of the body, including tissues and organs.
1st Acute lymphoblastic leukemia (ALL)
Acute lymphoblastic leukemia (ALL) is a type of cancer the abnormal growth of immature lymphocytes extreme overproduced from bone marrow and / or lymphatic system. Since it has a tendency to multiply rapidly, it can lead to death of the other normal white blood cells in bone marrow and / or lympaphatic system. All in all, cells appear immature in the blood stream.
Acute lymphoblastic leukemia (ALL) is the most common form of children with leukemia about 80% of all cases.
2nd Acute myeloid leukemia (AML)
Acute myeloid leukemia (AML) is cancer of the lining of myeloid cause of the rapid growth of abnormal granulocytes accumulated in the bone marrow, interferes with normal blood cells. In AML, immature granulocytes appear in the blood stream.
B. Chronic Leukemia
Chronic leukemia is defined as a state of slow, but still excessive buildup of relatively mature abnormal white blood cells. It is a tendency to spread slowly to other parts of the body through the bloodstream and / or lymphatic system.
1st Chronic lymphocytic leukemia (CLL)
Chronic lymphocytic leukemia (CLL) is defined as a condition of slow growth and spread of a group of abnormal white blood cells called B-cell lymphocytes, which fight infection in your body to produce antibodies. In CLL, B-cell lymphocytes have become abnormal and grow out of control. They appear less immature in the bloodstream.
2nd Chronic myelogenous leukemia (CML)
Chronic myelogenous leukemia (CML) is defined as a condition of slow growth and spread of abnormal granulocytes. In CML, granulocytes have become abnormal and grow uncontrollably in the bone marrow and / or the lymphatic system and appear to be less immature blood stream.
myeloid leukemia
A. Acute myeloid leukemia (AML)
Acute myeloid leukemia (AML) is cancer of the lining of myeloid cause of the rapid growth of abnormal granulocytes accumulated in the bone marrow, interferes with normal blood cells. In AML, immature granulocytes appear in the blood stream.
A.1. symptoms
1st Fatigue and pale complexion
Fatigue is a result of not enough red blood cells to carry oxygen to body cells. Pale complexion, if the disease affects red blood cells.
2nd infection
As the white blood cells do not function normally in the fight against foreign invasion, such as viruses and bacteria.
3rd shortness of breath
Because anemia
4th bone pain
In one or more bones in the stomach
5th abdominal swelling
Due to the spread of disease to lymph nodes or infectious cause swelling elsewhere in the body
6th bruises
Because of reduced blood platelet count.
7th Poor healing of minor cuts
The disease had an impact on platelet function.
8th unusual bleeding
As the bone marrow can not produce enough platelets to normal blood clot, such as frequent nosebleeds and bleeding gums
9th Prolonged or severe illness
This may be the cause of immunodeficiency due to abnormal white blood cells.
11th Etc..
A.2. Causes and Risk Factors
1st age
1st age...
2nd race
Men have an increased risk of acute myeloid leukemia (AML) than women.
3rd radiation
Children with previous high dose radiotherapy and chemotherapy are at increased risk of acute lymphoblastic leukemia.
4th Exposure to Environmental Chemicals
Exposure to certain chemicals may increase the risk of disease.
5th previous cancer treatment.
Preliminary treatment of cancer chemotherapy and radiotherapy increase the risk of AML.
6th Smoking
AML is linked to cigarette smoke, as a result of tobacco carcinogens.
7th genetic disorder
Certain inherited genetic diseases such as Down's syndrome, Fanconi anemia, IgA deficiency, and so increase the risk of disease.
8th Etc..
A.3. Diagnosis and Tests
If you have some of the symptoms gore.prvi test that your doctor order a complete blood count after the collection of your medical history and physical examination.
1st physical examination
At physical examination, the doctor can examine the signs of bruising, bleeding, swelling of lymph nodes, etc.
2nd Complete blood count
Complete blood count is very important if your doctor suspects that there May be a sign of development of AML. The test will reveal your doctor degree of abnormal white blood cells, red blood cells (anemia) and platelets (thrombocytopenia).
