Description

Leukemia is a type of blood cancer that begins in the bone marrow and results in a large number of abnormal blood cells. These blood cells, often known as blasts or leukaemia cells, are not fully matured. Bleeding and bruising, bone discomfort, weariness, fever, and a higher risk of infection are all possible symptoms. A shortage of regular blood cells causes these symptoms. Blood tests or a bone marrow biopsy are usually used to make the diagnosis. Leukemia's actual aetiology is unknown. Environmental (non-inherited) variables, as well as genetic factors, are thought to play a role. Smoking, ionising radiation, certain chemicals (such as benzene), previous chemotherapy, and Down syndrome are all risk factors. People with a history of leukaemia in their family are also at a higher risk. Acute Lymphoblastic Leukaemia (ALL), acute myeloid leukaemia (AML), Chronic Lymphocytic Leukaemia (CLL), and Chronic Myeloid Leukaemia (CML) are the four most prevalent kinds of leukaemia, with a few others.

In addition to supportive care and palliative care, treatment may include a mix of chemotherapy, radiation therapy, targeted therapy, and bone marrow transplant. Certain kinds of leukaemia can be treated by waiting and watching. Treatment success is determined on the kind of leukaemia and the patient's age. In the industrialized world, outcomes have improved. In the United States, the five-year survival rate is 57%. Depending on the kind of leukaemia, the five-year survival rate in children under 15 is more than 60% or even 90%. The disease is unlikely to reappear in children with acute leukaemia who have been cancer-free for five years.

Signs and Symptoms

Frequent bleeding, pale complexion, fever, and an enlarged spleen or liver are the most prevalent symptoms in youngsters. Damage to the bone marrow causes a paucity of blood platelets, which are vital in the clotting process, by replacing normal bone marrow cells with increased numbers of immature white blood cells. This means that persons with leukaemia are more likely to bruise easily, bleed profusely, or have pinprick bleeding.

White blood cells, which help fight viruses, might be repressed or malfunctioning. This might make the person's immune system incapable of fighting off a simple infection, or it could drive the immune system to target other bodily cells. Because leukaemia impairs the immune system's ability to function normally, some patients have infections on a regular basis, which can range from infected tonsils, mouth sores, or diarrhoea to lifethreatening pneumonia or opportunistic infections. Finally, a lack of red blood cells causes anemia, which can induce dyspnea and pallor. Other flu-like symptoms include feeling unwell, experiencing fevers, chills, night sweats, being tired, and other flu-like symptoms. Due to an enlarged liver and spleen, some patients suffer nausea or a sense of fullness, which can lead to accidental weight loss. Blasts afflicted by the illness may clump together and swell in the liver or lymph nodes, resulting in discomfort and nausea.

If leukemic cells infiltrate the central nervous system, neurological symptoms (particularly headaches) may develop. Brain stem pressure can cause unusual neurological symptoms such as headaches, seizures, or coma. All of the symptoms of leukaemia can be linked to other illnesses. As a result, medical tests are used to detect leukaemia. The name leukaemia, which means "white blood," comes from the high white blood cell count that most persons with leukaemia have before treatment. When a blood sample is examined under a microscope, the excessive quantity of white blood cells is visible, with the additional white blood cells typically being immature or malfunctioning. An excessive number of cells can also interfere with the amount of other cells, resulting in a dangerous blood count imbalance. During a routine blood count, person with leukaemia do not have elevated white blood cell counts. Leukemia is the name for this less prevalent disease. Cancerous white blood cells still exist in the bone marrow, disrupting normal blood cell formation, but they remain in the marrow rather than entering the circulation, where they would be evident in a blood test. White blood cell levels in the bloodstream might be normal or low in people with a leukemia. Leukemia can affect any of the four forms of leukaemia, however it is more frequent in hairy cell leukaemia.
