Introduction

Cancers known as leukemias begin in cells that would typically mature into different types of blood cells. Although some leukemias begin in other blood cell types, leukaemia often begins in young white blood cells. Leukemia comes in a variety of forms, which are categorised mostly according to whether the disease is acute and rapidly growing or chronic and whether it originates in lymphoid or myeloid cells. Although acute myeloid leukaemia (AML) initially develops in the bone marrow, it frequently spreads swiftly into the blood as well. It can occasionally spread to the lymph nodes, liver, spleen, testicles, central nervous system and other organs of the body [1].

Description

When a bone marrow cell experiences genetic alterations, it produces acute myelogenous leukaemia. In the past 30 years, the prognosis for people with acute myeloid leukaemia has improved. Unlike other malignancies, much of this advancement is due to improved supportive care rather than the development of new medications. Morbidity and mortality after allogeneic stem cell transplantation have significantly decreased, thanks to the development of antibacterial and antifungal medications, antiemetics and enhanced transfusion support. 90% of older patients and more than half of patients in their 20s still pass away from their illness. Acute lymphoblastic leukaemia is the most frequent type of leukaemia in children, followed by acute myeloid leukaemia. In addition, it is known as acute nonlymphocytic leukaemia. This particular cancer type affects the blood. There is still some debate over the exact source of this illness.

There are various forms of leukaemia. Some leukaemia types are more prevalent in children. Most cases of other types of leukaemia are in adults. Usually, leukaemia affects white blood cells. Your white blood cells are effective infection-fighting agents; they typically grow and divide in an organised manner as required by your body. But in leukaemia patients, the bone marrow makes an overwhelming number of aberrant, dysfunctional white blood cells. Depending on the leukemia's kind and other variables, treatment for leukaemia may be difficult. However, there are methods and tools that can aid in the success of your treatment.

Hematologist-oncologists typically treat leukaemia. These medical professionals are experts in cancer and blood conditions. The type and stage of the cancer determine the course of treatment. The patient's general health and other medical issues also play a role. Leukemia can be diagnosed using a variety of diagnostic assays. RBC, WBC and platelet counts are determined via a complete blood count. Your blood can also be examined under a microscope to see if the cells have an odd appearance. To check for signs of leukaemia, tissue biopsies from the lymph nodes or bone marrow can be performed. These tiny samples can determine the leukemia's type and growth rate.

Less healthy white blood cells, platelets and red blood cells are produced and discharged into your blood. Your body's organs and tissues won't receive the oxygen they require to function correctly as a result. Additionally, your body won't be able to create blood clots as necessary or fight infections. Fever, or an elevated body temperature, is frequently experienced by people with leukaemia. Additionally, this may cause night sweats, which are periods of visible perspiration while you sleep. As one of the body's responses to infection is fever, it's probable that this represents the body's attempt to eradicate leukaemia cells. Leukemia increases the likelihood of contracting infections, which can result in fever and night sweats.

In targeted therapy, certain genes or proteins required for the growth of cancer cells are blocked by medications. This therapy has the ability to either kill leukaemia cells directly or inhibit the signals they utilise to proliferate and grow. Through a stem cell transplant, the blood-producing leukaemia cells in your bone marrow are replaced. Your body's fresh stem cells might be obtained by your doctor from you or from a donor. To start, you'll receive intense chemotherapy treatments to eradicate the cancer cells in your bone marrow. The fresh stem cells will then be infused into a vein in your body. They will develop into brand-new, wholesome blood cells [2-4].

Stem cells are typically produced in the bone marrow and allowed to mature completely before being discharged into the blood. However, in acute leukaemia, the bone marrow begins secreting a significant amount of blast cells, which are immature white blood cells.Red blood cells and platelet cells are less numerous as the number of blast cells rises. This decrease raises the risk of excessive bleeding and creates anaemia symptoms like fatigue. Additionally, blast cells are less effective in battling viruses and bacteria than mature white blood cells, which leaves you more susceptible to infection. Acute lymphoblastic leukaemia is the most frequent kind of cancer in children, although being generally rare [5].

Conclusion

White blood cells, which fight infection, red blood cells, which carry oxygen and platelets, which aid in blood clotting, are the three different cell types found in blood. Your bone marrow produces billions of new blood cells each day, the majority of which are red blood cells. Your body produces more white cells than it needs when you have leukaemia. These leukaemia cells lack the ability of healthy white blood cells to combat infection. And since there are so many of them, your organs' functionality begins to suffer. You can run out of platelets to clot your blood, red blood cells to carry oxygen, or healthy white blood cells to combat infection over time.
