Leukemia - Human Health
Leukemia is a type of cancer that begins in the bone marrow, which is the soft tissue in bone is responsible for producing red blood cells, white blood cells, and platelets. Some cells can turn into leukemia cells, which then divides into more healthy cells. For cancer of the bone marrow to create more leukemia cells, healthy cells pushing them out and replace them, making it difficult for blood to function properly, and that leads to serious medical problems.
There are four main types of leukemia into two categories depending on how the leukemia took place and the difference between normal and abnormal cells.
Acute leukemia
Acute Myelogenous Leukemia (AML) is cancer that spreads rapidly in the blood and bone marrow. Because the original leukemic cells, bone marrow blasts produce a variety of, or not, nonfunctional cells. Under healthy conditions, these cells will develop into blood cells that fight infection white, red blood cells carry oxygen throughout the body, or platelets to help clotting. However, in the AML, these blasts did not develop normally and inhibit the production of new cells.
Acute Lymphocytic Leukemia (ALL) is cancer that are similar to acute myelogenous leukemia exception, rather than affecting all cell types, starting in lymphocytes. Lymphocytes are white blood cells that defend the body against infection. Bone marrow cells has not been made known as the blasts, which in healthy people will become lymphocytes. ALL the people, however, these blasts do not normally develop into white blood cells. The cells are abnormal then took place in the mind is usually devoted to healthy cells, and inhibit the creation of new cells. This process can result in a reduction of red blood cells and the development of anemia, as well as a reduction of white blood cells that leads to a weak immune system.
Chronic Leukemia
Chronic Lymphocytic leukemia (CLL), such as the type of leukemia, developed in the blood and bone marrow. Chronic leukemia take place in slow rate of acute leukemia, but still affects the lymphocytes, which normally fight infection. Make too many CLL lymphocytes are nonfunctional healthy cells to take place. As cancer cells continue to multiply, they inhibit the effectiveness of functional lymphocytes, which leads to a weak immune system. Slow healing, and anemia can also occur in patients as a CLL cells, red blood and platelets are replaced by the abnormal lymphocytes.
Chronic myeloid leukemia (CML) is a slow-growing type of leukemia that makes almost-functional marrow-red blood cells, white, and platelets in disproportionate numbers. Many white blood cells and platelets are made, while the number of red blood cells are formed. Blood flow begins to slow as the number of white blood cells increased and the patient may experience severe anemia due to a decrease in blood cells red.
The symptoms for each type of leukemia vary, but common symptoms include fever and chills, fatigue, frequent infections, loss of appetite and weight, swollen lymph nodes, easy bruising or bleeding, shortness of breath, bone pain, night sweats, and bleeding into the skin.
Complete blood Count, or CBC, is a blood test that measures the count of red blood cells, white blood cell count, hemoglobin level and platelet count, among others. This is generally used to diagnose leukemia. Another method used for diagnosing leukemia including marrow biopsies, spinal fluid tests, physical exams, screenings chromosomes, and chest X-rays.
Treatment for leukemia may include chemotherapy, radiation, biological therapy, targeted therapies such as kinase inhibitors, and bone marrow and stem-cell transplantations.
