Symptoms and Diagnosis of Leukemia Cancer
In its initial stage, these leukemias are asymptomatic in 60% of the cases are detected only after performing a routine laboratory, which is an increase in lymphocytes.
As the disease progresses, we see the presence of lymphadenopathy and organomegaly to increase as greater the number of lymphocytes.
You also have other symptoms caused by the decrease in the number of other blood cells such as red blood cells and platelets.
The anemia does not occur in the first stage of the disease, but when the bone is affected by the invasion of lymphocytes, there is a decrease of red blood cells. Anemia produces pallor, fatigue, shortness of breath and tachycardia.
Sometimes bleeding is shown by the decrease in platelets. They are serious when the platelet count is below 10,000 per ml and will not happen if the decline is not very intense (50,000 per ml).
It may not be reached to produce a large hemorrhage and that lack of platelets occurs only bruising, bleeding gums or nosebleeds mild.
What are Chronic Leukemia?
There are several types of chronic leukemia cells depending altered. On the one hand, there are chronic lymphoproliferative syndromes, and other chronic myeloproliferative disorders.
Chronic lymphoproliferative syndromes are a series of diseases caused by the uncontrolled growth (neoplastic nature) of mature-looking cells that present with a peripheral blood involvement.
Most of these syndromes are caused by abnormal growth and proliferation of B lymphocytes Chronic lymphocytic leukemia is, in these syndromes, the most common in Western populations.
Chronic myeloproliferative syndromes are due to an alteration of stem cells or blood-forming, which is used to increase the number of precursor cells and mature cells derived from them. Among these syndromes, is chronic myeloid leukemia.
COMPOSITION OF THE BLOOD
The bone marrow, which is inside the bones, is composed of hematopoietic cells by fat cells and supporting tissues.
Hematopoietic stem cells reproduce continuously to form new cells. Some of these, will turn new stem cells and others, when mature, will become red blood cells, white cells and platelets.
Red blood cells, erythrocytes or red blood cells are responsible, through a component called hemoglobin, carry oxygen from the lungs to tissues and carbon monoxide in the opposite direction. Red blood cells are produced in the bone marrow at a rate of about two million per second. If they decrease, anemia will occur and will not be enough oxygen to the tissues.
