Abstract

Leukemia is a type of blood and bone marrow cancer. Cancer is defined as the uncontrollable proliferation of aberrant cells. Cancer can occur in any part of the body. This rapid, out-of-control development of aberrant cells occurs in the bone marrow of leukemia patients. These aberrant cells subsequently make their way into the bloodstream. Unlike other malignancies, leukemia does not usually create a mass (tumor) that may be detected on imaging tests like X-rays. There are numerous different forms of leukemia. Some are more prevalent in children, while others are more prevalent in adults. Treatment is determined by the type of leukemia you have as well as other factor Each year, approximately 14 new cases of leukemia are diagnosed in the United States for every 100,000 men and women, for a total of 61,000 new cases.

Introduction

According to the number of new cases diagnosed each year, it is the tenth most prevalent cancer. In the United States, leukemia accounts for 3.5%of all new cancer cases. Leukemia is frequently thought to be a childhood disease, yet it affects significantly more adults. In fact, the risk of having this cancer rises with age. Leukemia is most commonly diagnosed in adults aged 65 to 74. Men are more likely to develop leukemia than women, and Caucasians are more likely to develop leukemia than AfricanAmericans. Although leukemia is uncommon in children, 30% of children and adolescents who have any type of malignancy will develop some form of leukemia. Although leukemia is rare in children, of the children or teens who develop any type of cancer, 30% will develop some form of leukemia. Leukemia originates in the bone marrow's growing blood cell [1 ]. All blood cells begin as hematopoietic stem cells (hemo = blood; poiesis = make). The stem cells go through several stages of development before reaching adulthood. First, blood stem cells differentiate into either myeloid or lymphoid cells. If blood cells continued to develop properly, the adult forms of these cells would be as follows: Myeloid cells mature into red blood cells, platelets, and some types of white blood cells (basophils, eosinophils and neutrophils). Lymphoid cells mature into certain types of white blood cells (lymphocytes and natural killer cells). The other cell types (red blood cells, white blood cells, and platelets) have very little space and support inside the bone marrow to grow and reproduce.

As a result, fewer normal blood cells are produced and released into the circulation, while more leukemia cells are produced and released into the blood. Without an adequate number of regular blood cells, your organs and tissues will not receive the oxygen they require to function properly, and your body will be unable to fight infection or coagulate blood as needed. Leukemia cells are often immature (yet to mature) white blood cells. The term "leukemia" is derived from the Greek words for "white" (leukos) and "blood" (haima). When looking at blood using a microscope, an excess of white blood cells is seen, and the true appearance of the blood is lighter to the human eye Acute leukemia is the fastest growing type of leukemia. The leukemia cells divide swiftly, and the disease advances quickly [2]. If you have acute leukemia, you will have symptoms within weeks of the leukemia cells developing. The most frequent type of juvenile malignancy is acute leukemia. Leukemia is a chronic disease. These leukemia cells frequently exhibit characteristics of both immature and adult cells. Some of these cells may have matured to the point where they function as the cells they were designed to be, but not to the same extent as their normal counterparts. When opposed to acute leukemia, the disease often worsens slowly. If you have chronic leukemia, you may not notice any signs for several years. There are other subtypes of leukemia in addition to the four major kinds of leukemia. Hairy cell, Waldenstrom's macroglobulinemia, prolymphocytic, and lymphoma cell leukemia are all subtypes of lymphocytic leukemia.

Myelogenous, promyelocytic, monocytic, erythroleukemia, and megakaryocytic leukemia are all subtypes of myelogenous leukemia. Leukemia develops when the DNA of a single cell in the bone marrow alters (mutates), causing it to be unable to develop and function normally. (DNA is the cell's "instruction code" for growth and function.) Genes are made up of segments of DNA that are organized on bigger structures known as chromosomes.) The mutated DNA is present in all cells that develop from the first mutant cell. In most situations, it is still unknown what causes the DNA damage in the first place. Scientists have identified alterations in specific chromosomes in patients with various forms of leukemia [3].

IMMUNITY AND COAGULATION

The horseshoe crab (Limulus Polyphemus) lacks specialized phagocytic cells and platelets, although it does exhibit big nucleated amoeboid granular hemolytic [4]. When their open circulatory system is compromised, they respond to microbial threats via a similar amoebocyte- and humoral-mediated inflammatory and clotting route. Lysates generated from Limulus amebocytes have long been known to coagulate when exposed to endotoxin and have been used to detect that endotoxin. Human platelets exhibit Limulus amebocyte-like characteristics such as aggregation, adhesion, spreading, and granulebased coagulation factor release. These characteristics have been observed throughout phylogenetic evolution as common antimicrobial and proinflammatory responses to stimuli that activate both the clotting cascade and phagocytic effector cells [5,6]. The cell size and dimensions of thrombocyte nuclei have gradually shrunk; this process has intensified as animals have become more terrestrial and have begun to thermoregulation. Circulating nucleated thrombocytes in the jawless fish-like Hagfish (Myxine glutinosa), cartilaginous fish-like sharks (Squalus acanthi as), boney fishes like Zebrafish (Danio rerio), and other fish species have some phenotypic and functional characteristics similar to those of mammalian platelets. As aquatic animals such as the lungfish (Neoceratodus forsteri, Lepidosiren paradoxa) adapted to terrestrial life, thrombocytes remained large and retained large nuclei, while developing a sophisticated granule system to effectively regulate and maintain coagulation and immune functions, especially during the dramatic changes associated with dry-season estivation or dormancy. Platelets are important a nucleate elements of the immune and hemostatic systems with minimal nucleotide- or protein synthesis machinery to make new gene products indefinitely; their ability to reproduce viral particles is limited or has only been demonstrated for a few single-stranded-RNA viruses such as Dengue virus and potentially SARS-CoV-2 [7]. Some viral replication can be avoided by limiting gene expression to a pre-existing, limited subset of ribosomebound messenger RNAs that engage the ribosomal rescue-factor pelota in messenger-RNA decay regulation. There is also the possibility that viral replication occurs in megakaryocytes within the bone marrow prior to their budding from parent cells, but this has not been well investigated. Despite being ignored as part of plasma evolutionary biology to date, platelets provide a more vital function. Being born with a genetic condition, such as neurofibromatosis, Klinefelter syndrome, Schwachman-Diamond syndrome, or Down syndrome.

Anyone can develop leukemia. You can have leukemia even if you don't have any of these risk factors. Others have one or more of these risk factors but never develop leukemia. You cannot "catch" leukemia from another person. It is not "passed" from one person to another. Leukemia can strike anyone at any time. You can have leukemia even if you don't have any of these risk factors. Others have one or more of these risk factors but never develop leukemia. You cannot "catch" leukemia from another person. It is not "spread" from one person to another. Leukemia develops when the DNA of a single cell in the bone marrow alters (mutates), causing it to be unable to develop and function normally. (DNA is the cell's "instruction code" for growth and function.) Genes are made up of segments of DNA that are organized on bigger structures known as chromosomes [8]. The mutated DNA is present in all cells that develop from the first mutant cell. In most situations, it is still unknown what causes the DNA damage in the first place. Scientists have identified alterations in specific chromosomes in patients with various forms of leukemia. Although the specific source of the DNA mutation that causes leukemia is unknown, scientists have identified numerous risk factors that may raise your chances of acquiring leukemia.

Conclusion

Smoking or dealing with industrial chemicals in the past. Cancercausing substances benzene and formaldehyde are found in tobacco smoke, construction materials, and household chemicals. Plastics, rubbers, dyes, insecticides, pharmaceuticals, and detergents all contain benzene. Formaldehyde is found in numerous home items, including soaps, shampoos, and cleaning products.
