Leukemia is cancer of the blood forming tissues that also affects the bone marrow and the lymphatic system. Such a type of cancer causes abnormal development of cells that gradually enter the bloodstream [1].
Presentation
Symptoms of leukemia vary with the type. The common symptoms of the disease include the following [9]:
- Undue weight loss
- Constant felling of tiredness and fatigue
- Pain in bone
- Fever accompanied by chills
- Excessive sweating especially during night hours
- Easy prone to infections
- Bleeding or bruising very easily
- Hepatomegaly
- Splenomegaly
- Swollen lymph nodes
- Development of petechiae

Easy Bruising
Acute leukemia usually develops quickly and tends to cause fatigue, easy bruising, and frequent infections. Chronic leukemia usually develops slowly, with the leukemia cells working almost as well as normal white blood cells. [uabmedicine.org]
Then also because of the platelets can be affected a lot of times patients will present with bleeding or easy bruising. We sometimes see what we call petechiae, which is just a medical word for small red dot under the skin. [youtube.com]
However, common signs of the disease include fever, tiring easily, pale skin tone, easy bruising and bleeding, swollen lymph nodes, unplanned weight loss, joint pain and tenderness, night sweats, and frequent infections.4 Myth #4: Survival is rare Reinforce [hematologyadvisor.com]
Side effects can include hair loss, mouth sores, loss of appetite, nausea and vomiting, diarrhea, increased chance of infections (due to low white blood cell counts), easy bruising or bleeding (due to low blood platelet counts) and fatigue (due to low [cancersupportcommunity.org]

Anemia
Anemia and thrombocytopenia are the major adverse prognostic variables. CLL has no standard staging system. [web.archive.org]
Stage A: The patient does not have anemia or low levels of platelets. The leukemia can be felt in fewer than 3 areas of lymph nodes (Rai stages 0, I and II). Stage B: The patient does not have anemia or low levels of platelets. [cancer.net]
They also crowd out the normal cells in the marrow, causing a decrease in the number of new normal cells made in the marrow and resulting in a low red cell count (anemia). [hopkinsmedicine.org]
They also may get anemia, which is when there's a low number of red blood cells. This happens because leukemia cells crowd the bone marrow. This prevents bone marrow from making the usual amount of oxygen-carrying red blood cells. [kidshealth.org]

Exposure to Benzene
But some things can increase your risk of getting AML, including: previous chemotherapy or radiotherapy exposure to very high levels of radiation (including previous radiotherapy treatment) smoking and other exposure to benzene, a chemical used in manufacturing [nhs.uk]
For example, exposure to benzene is a risk factor for AML. It may also be a risk factor for acute lymphocytic leukemia (ALL). [urmc.rochester.edu]
This includes earlier exposure to chemotherapy, Down’s syndrome and other genetic disorders, exposure to benzene and other chemicals, exposure to radiation therapy etc. [news-medical.net]
Chronic exposure to benzene in the workplace and exposure to extraordinary doses of irradiation can be causes of the disease, although neither explains most cases. Return to top Treatment The aim of treatment is to bring about a complete remission. [web.archive.org]

The following are the various diagnostic procedures for detecting leukemia [10]:
- A preliminary physical examination will be carried out for studying the various signs and symptoms of leukemia.
- Blood tests such as complete blood count provide a useful insight for diagnosis of the condition.
- Bone marrow test forms an important part of the diagnostic procedure. In this a sample of the bone marrow is derived from the hip bone and studied for the presence of leukemia cells.

Treatment
Treating leukemia is a complex process as it would greatly depend on the stage of the disease and the type of leukemia present. Some of the common treatment methods employed for treating the condition are explained below [11]:
- Chemotherapy: It is the method of choice for treating leukemia [11].
- Biological therapy: In this method, therapies are targeted towards making the immune system recognize the cancer cells as invaders and attack them.
- Radiation therapy: Radiation therapy employs high beam radiation to kill the target cells and arrest their growth.
- Targeted therapy: In this form of therapy, drugs are administered that attack specific component of the leukemia cells thereby preventing their growth and multiplication.
- Stem cell transplant: In this, the affected bone marrow is transplanted with a healthy one. The prognosis of the disease is favorable with this kind of method [12]. Prior to this method, the patient is given chemotherapy in combination with radiation therapy to completely destroy the diseased bone marrow.
Prognosis
Prognosis of the disease condition depends on the type of leukemia and the stage at which the condition was diagnosed. If leukemia is diagnosed in its early stages then the prognosis is favorable with timely initiation of treatment and regular follow up checkups [8].
Etiology
The factor that triggers the development of leukemia is yet to be figured out. However, a combination of various factors such as environment and heredity are known to play foul. In addition, various types of risk factors such as exposure to chemical compounds such as benzene, tobacco smoking, ionizing radiation and prior treatment with chemotherapy can also predispose an individual to develop leukemia [3] [4].
Epidemiology
Leukemia is a widespread problem affecting the male and female population equally. It has been estimated that every year about 13.0 per 100,000 fresh cases of leukemia are diagnosed. Statistics also reveal that there were about 7.0 per 100,000 cases of death due to leukemia every year. Researchers have also established statistical data which state that in the year 2014, there would be 52,380 new cases of leukemia. Of these, 24,090 cases of death due to leukemia would also occur in the same year. Statistical data has also confirmed that leukemia accounts for 4.1% of all cancer deaths. This form of cancer is also widely prevalent amongst the pediatric population [5] [6]. It has been estimated that each year in US about 2500 – 3500 new cases are diagnosed [1].
Pathophysiology
Leukemia begins with attacking the white blood cells of the body. As a result of this, the infection fighting ability of the white blood cells is greatly diminished making the body more prone to contract infectious diseases. Leukemia also affects the bone marrow as a result of which abnormal cells are produced which fail to function in the normal way. Such sequence of events causes the abnormal cells to affect other body organs such as the liver, eye and the spleen. There are basically 4 types of leukemia, namely: Acute lymphocytic leukemia, acute myelogenous leukemia, chronic lymphocytic leukemia and chronic myeloid leukemia. Other rare types of leukemia are myeloproliferative disorders, hairy cell leukemia and myelodysplastic syndromes [7].
Prevention
It is practically not possible to prevent leukemia. However, the spread of the disease can be prevented if detected on time and timely initiation of treatment.
Summary
There are several forms of leukemia; some which affect the children and some which affect the adult population. Leukemia usually begins by primarily attacking the white blood cells which are essential for warding off infections. But, when the cancer affects the white blood cells, these are no longer capable of safeguarding the body against infections. The underdeveloped white blood cells are known as blasts or leukemia cells [2]. Treatment of leukemia is a complex process that needs to be designed keeping in mind several factors.
Patient Information
Definition
Leukemia is the cancer of the white blood cells that also affects the lymphatic system and the bone marrow. It is a common condition affecting the children as well as the adult population.
Cause
The exact factor that triggers the abnormal development of cells is not clearly understood. However, interplay of environment and genetic factors are known to play foul in causation of leukemia.
Symptoms
Symptoms of leukemia include fatigue, tiredness, unexplained weight loss, fever and chills, frequent nose bleeds, excessive sweating and bone pain along with tenderness.
Diagnosis
Diagnosis of leukemia is done by blood tests to determine complete blood count which would give an idea about the white blood cell count. In addition to this, bone marrow test is also done to analyze for the presence of leukemia cells.
Treatment
Treatment of leukemia consists of chemotherapy and radiation therapy which targets the cancer cells and destroys them. In addition, stem cell transplant is also the method of choice wherein the diseased bone marrow is replaced with a healthy one. Patients suffering from leukemia are also given targeted therapy which works by destroying specific components of the leukemia cells.
