Is Leukemia Hereditary? Risks, Prevention and More
Leukemiaalso known as leukaemiais a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal term paper about leukemia cells. The exact cause of leukemia is unknown. Treatment may involve some combination of chemotherapyradiation therapytargeted therapyand bone marrow transplantin addition to supportive care and palliative care as needed. Outcomes have improved in the developed world. Inleukemia was present in 2.
Clinically and pathologically, leukemia is subdivided into a variety of large groups. The first division is between its acute and chronic forms: [15]. Additionally, the diseases are subdivided according to which kind of blood cell is affected. This divides leukemias into lymphoblastic or lymphocytic leukemias and myeloid or myelogenous leukemias : [15].
Combining these two classifications provides a total of four main categories. Within each of these main categories, there are typically several subcategories. Finally, some rarer types are usually considered to be outside of this classification scheme. The most common symptoms in children are easy bruisingpale skinfeverand an enlarged spleen or liver. Damage to the bone marrow, by way of displacing the normal bone marrow cells with higher numbers of immature white blood cells, results in a lack of blood plateletswhich are important in the blood clotting process.
This means people with leukemia may easily become bruisedbleed excessively, or develop pinprick bleeds petechiae. White blood cellswhich are involved in fighting pathogensmay be suppressed or dysfunctional. This could cause the person's immune system to be unable to fight off a simple infection or to start attacking other body cells. Because leukemia prevents the immune system from working normally, some people experience frequent infectionranging from infected tonsilssores in the mouthor diarrhea to life-threatening pneumonia or opportunistic infections, term paper about leukemia.
Finally, the red blood cell deficiency leads to anemiawhich may cause dyspnea and pallor. Some people experience other symptoms, such as feeling sickterm paper about leukemia, having fevers, chills, night sweats, feeling fatigued and other flu-like symptoms.
Some people experience nausea or a feeling of fullness due to an enlarged liver and spleen ; this can result in unintentional weight loss. Blasts affected by the disease may come together and become swollen in the liver or in the lymph nodes causing pain and leading to nausea. If the leukemic cells invade the central nervous systemthen neurological symptoms notably headaches can occur. Uncommon neurological symptoms like migrainesseizuresor coma can occur as a result of brain stem pressure, term paper about leukemia.
All symptoms associated with leukemia can be attributed to other diseases. Consequently, leukemia is always diagnosed through medical tests. The word leukemiawhich means 'white blood', is derived from the characteristic high white blood cell count that presents in most term paper about leukemia people before treatment, term paper about leukemia.
The high number of white blood cells is apparent when a blood sample is viewed under a microscopewith the extra white blood cells frequently being immature or dysfunctional. The excessive number of cells can also interfere with the level of other cells, causing further harmful imbalance in the blood count, term paper about leukemia.
Some people diagnosed with leukemia do not have high white blood cell counts visible during a regular blood count. This less-common condition is called aleukemia. The bone marrow still contains cancerous white blood cells that disrupt the normal production of blood cells, but they remain in the marrow instead of entering the bloodstream, where they would be visible in a blood test.
For a person with aleukemia, the white blood cell counts in the bloodstream can be normal or low. Aleukemia can occur in any of the four major types of leukemia, and is particularly common in hairy cell leukemia. There is no single known cause for any of the different types of leukemias.
The few known causes, which are not generally factors within the control of the average person, account for relatively few cases. The different leukemias likely have different causes. Leukemia, like other cancers, results from mutations in the DNA. Certain mutations can trigger leukemia by activating oncogenes or deactivating tumor suppressor genesand thereby disrupting the regulation of cell death, differentiation or division.
These mutations may occur spontaneously or as a result of exposure to radiation or carcinogenic substances. Among adults, the known causes are natural and artificial ionizing radiation and some chemicals, notably benzene and alkylating chemotherapy agents for previous malignancies.
Diet has very limited or no effect, although eating more vegetables may confer a small protective benefit. Viruses have also been linked to some forms of leukemia, term paper about leukemia. For example, human T-lymphotropic virus HTLV-1 causes adult T-cell leukemia.
A few cases of maternal-fetal transmission a baby acquires leukemia because its mother had leukemia during the pregnancy have been reported. Large doses of Sr emission from nuclear reactor accidents, nicknamed bone seeker increases the risk of bone cancer and leukemia in animals and is presumed to do so in people. Some people have a genetic predisposition towards developing leukemia.
This predisposition is demonstrated by family histories and twin studies. In some cases, term paper about leukemia tend to develop the same kinds of leukemia as other members; in other families, affected people may develop different forms of leukemia or related blood cancers.
In addition to these genetic issues, people with a chromosomal abnormalities or certain other genetic conditions have a greater risk of leukemia. Whether or not non-ionizing radiation causes leukemia has been studied for several decades. The International Agency for Research on Cancer expert working group undertook a detailed review of all data on static and extremely low frequency electromagnetic energy, which occurs naturally and in association with the generation, transmission, and use of electrical power.
Diagnosis is usually based on repeated complete blood counts and a bone marrow examination following observations of the symptoms. Sometimes, blood tests may not show that a person has leukemia, especially in the early stages of the disease or during remission. A lymph node biopsy can be performed to diagnose certain types of leukemia in certain situations. Following diagnosis, blood chemistry tests can be used to determine the degree of liver and kidney damage or the effects of chemotherapy on the person.
When concerns arise about other damages due to leukemia, term paper about leukemia, doctors may use an X-rayMRIterm paper about leukemia, or ultrasound. These can potentially show leukemia's effects on such body parts as bones X-raythe brain MRIor the kidneys, spleen, term paper about leukemia liver ultrasound, term paper about leukemia. CT scans can be used to check lymph nodes in the chest, though this is uncommon.
Despite the use of these methods to diagnose whether or not a person has leukemia, many people have not been diagnosed because many of the symptoms are vague, term paper about leukemia, non-specificand can refer to other diseases. For this reason, the American Cancer Society estimates that at least one-fifth of term paper about leukemia people with leukemia have not yet been diagnosed. Most forms of leukemia are treated with pharmaceutical medicationtypically combined into a multi-drug chemotherapy regimen.
Some are also treated with radiation therapy. In some cases, a bone marrow transplant is effective. Management of ALL is directed towards control of bone marrow and systemic whole-body disease.
Additionally, treatment must prevent leukemic cells from spreading to other sites, particularly the central nervous system CNS e. monthly lumbar punctures. Hematologists base CLL treatment term paper about leukemia both the stage and symptoms of the individual person. A large group of people with CLL have low-grade disease, which does not benefit from treatment.
Individuals with CLL-related complications or more advanced disease often benefit from treatment. In general, the indications for treatment are: [ citation needed ].
Most CLL cases are incurable by present treatments, so treatment is directed towards suppressing the disease for many years, rather than curing it. The primary chemotherapeutic plan is combination chemotherapy with chlorambucil or cyclophosphamideplus a corticosteroid such as prednisone or prednisolone.
The use of a corticosteroid has the additional benefit of suppressing some related autoimmune diseases, such as immunohemolytic anemia or immune-mediated thrombocytopenia.
In resistant cases, single-agent treatments with nucleoside drugs such as fludarabine[57] pentostatinor cladribine may be successful. Younger and healthier people may choose allogeneic or autologous bone marrow transplantation in the hope of a permanent cure. Many different anti-cancer drugs are effective for the treatment of AML. Treatments vary somewhat according to the age of the person and according to the specific subtype of AML.
Overall, the strategy is to control bone marrow and term paper about leukemia whole-body disease, while offering specific treatment for the central nervous system CNSif involved. In general, most oncologists rely on combinations of drugs for the initial, induction phase of chemotherapy. Such combination chemotherapy term paper about leukemia offers the benefits of early remission and a lower risk of disease resistance. Consolidation and maintenance treatments are intended to prevent disease recurrence.
Consolidation treatment often entails a repetition of induction chemotherapy or the intensification of chemotherapy with additional drugs. By contrast, maintenance treatment involves drug doses that are lower than those administered during the induction phase.
There are many possible treatments for CML, but the standard of care for newly diagnosed people is imatinib Gleevec therapy.
In a more advanced, term paper about leukemia, uncontrolled state, when the person cannot tolerate imatinib, or if the person wishes to attempt a permanent cure, then an allogeneic bone marrow transplantation may be performed. This procedure involves high-dose chemotherapy and radiation followed by infusion of bone marrow from a compatible donor.
Decision to treat People with hairy cell leukemia who are symptom-free typically do not receive immediate treatment. Treatment is generally considered necessary when the person shows signs and symptoms such as low blood cell counts e. Typical treatment approach People who need treatment usually receive either one week of cladribinegiven daily by intravenous infusion or a simple injection under the skin, or six months of pentostatingiven every four weeks by intravenous infusion.
In most cases, one round of treatment will produce a prolonged remission. Other treatments include rituximab infusion or self-injection with Interferon-alpha. In limited cases, the person may benefit from splenectomy removal of term paper about leukemia spleen.
These treatments are not typically given as the first treatment because their success rates are lower than cladribine or pentostatin. Most people with T-cell prolymphocytic leukemia, a rare and aggressive leukemia with a median survival of less than one year, require immediate treatment.
T-cell prolymphocytic leukemia is difficult to treat, and it does not respond to most available chemotherapeutic drugs. Alemtuzumab Campatha monoclonal antibody that attacks white blood cells, has been used in treatment with greater success than previous options.
Some people who successfully respond term paper about leukemia treatment also undergo stem cell transplantation to consolidate the response, term paper about leukemia. Treatment for juvenile myelomonocytic leukemia can include splenectomychemotherapyand bone marrow transplantation.
