What is Acute Leukemia?
Acute Leukemia is a type of cancer that develops in the body’s bone marrow. It originates when blood stem cells cannot mature, resulting in numerous white blood cells that do not function properly. It is also called Acute Lymphoblastic Leukemia. It is most common in children, although the recovery rate is high.
In 1857, German pathologist Nikolaus Friedrich documented the first case of Acute Leukemia. However, Wilhelm Ebstein, a German physician, was accredited with its discovery in 1889.
Acute Leukemia grows at a fast rate. Therefore, symptoms and signs appear at an early stage. The symptoms may include low white blood cell count, infections, tiredness, shortness of breath, bone or joint pains, etc. The bone marrow of a person diagnosed with this cancer produces many dysfunctional cells that overgrow the healthy marrow cells.
Blood samples and bone marrow are employed to detect this type of cancer. Being higher in intensity, Acute Leukemia is treated in various ways depending upon its severity. The treatment entails chemotherapy, stem cell therapy, or targeted therapy. The patient diagnosed with Acute Leukemia should be monitored regularly and in some cases, hospitalization may be necessary.
What is Chronic Leukemia?
Chronic Leukemia is fast-growing cancer that causes due to the underdevelopment of blood stem cells. It is the most common type of cancer in adults. They originate in the bone marrow but progresses towards the blood. The growth of cancerous cells in Chronic Leukemia is slow. As a result, early detection is possible. Therefore, the survival rate is high as well.
The symptoms may include tiredness, bone and joint pain, loss of appetite, night sweats, nosebleeds, etc. It is not much severe as compared to its acute counterpart.
The cells mature partly. Hence, they are not able to fight infections to their maximum capacity. They generally live longer than normal cells and invade the body. Therefore, one can live for years with this cancer.
Risk factors may include age over 60, being of European descent, exposure to high levels of benzene, Agent Orange, or radiation. The treatment differs with the severity of the condition. The various treatment necessary for such conditions includes chemotherapy, corticosteroids, and monoclonal antibodies.
Difference Between Acute and Chronic Leukemia
- Acute Leukemia has a slow growth of cancerous cells, whereas Chronic Leukemia has a fast growth.
- The former is due to immature blood stem cells, while the latter is due to the underdevelopment of blood stem cells.
- Acute Leukemia has low white blood cell count, pale skin, infection, shortness of breath, etc., as its main symptoms. On the other hand, tiredness, weight loss, night sweats, and loss of appetite are symptoms of Chronic Leukemia.
- The severity of cases is higher for Acute Leukemia than for Chronic Leukemia.
- Targeted therapy or stem cell therapy are tools for Acute Leukemia treatment, whereas corticosteroids or monoclonal antibodies are for Chronic Leukemia treatment. Chemotherapy is routine for both.
- The survival rate for Acute Leukemia is lower than that of Chronic Leukemia.
- The former is most common in children, whereas the latter is more common in adults.
