Leukemia is a type of cancer that starts in the blood-forming tissue of the bone marrow. It is a cancer of the white blood cells, which are part of the body's immune system. Leukemia cells can spread to other parts of the body, including the lymph nodes, spleen, liver, and brain.
There are many different types of leukemia. The most common types are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). ALL is more common in children, while AML is more common in adults. Other types of leukemia include chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML).
Leukemia can be a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.

Leukemia is a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
Cancer of White Blood Cells
Leukemia is a cancer of the white blood cells. White blood cells are part of the body's immune system. They help to fight infection and disease.
- Uncontrolled growth: In leukemia, the white blood cells start to grow and multiply uncontrollably. This can lead to a buildup of abnormal white blood cells in the bone marrow and blood.
- Immature cells: The leukemia cells are often immature and do not work properly. This can make it difficult for the body to fight infection.
- Spread to other organs: Leukemia cells can spread from the bone marrow to other parts of the body, including the lymph nodes, spleen, liver, and brain. This can cause a variety of symptoms, depending on the organs that are affected.
- Different types: There are many different types of leukemia. The most common types are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). ALL is more common in children, while AML is more common in adults. Other types of leukemia include chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML).
Leukemia can be a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
Starts in Bone Marrow
The bone marrow is a soft, spongy tissue found inside the bones. It is responsible for producing blood cells, including white blood cells. In leukemia, the leukemia cells start to grow and multiply uncontrollably in the bone marrow.
- Overcrowding: As the leukemia cells multiply, they start to crowd out the healthy blood cells in the bone marrow. This can lead to a shortage of healthy white blood cells, red blood cells, and platelets.
- Anemia: A shortage of red blood cells can lead to anemia, which is a condition in which the body does not have enough healthy red blood cells to carry oxygen to the tissues. Symptoms of anemia include fatigue, shortness of breath, and pale skin.
- Infection: A shortage of white blood cells can make it difficult for the body to fight infection. People with leukemia are more likely to get infections, and these infections can be more serious.
- Bleeding: A shortage of platelets can lead to bleeding problems, such as easy bruising and nosebleeds. Platelets help to stop bleeding by forming clots.
Leukemia can also cause other symptoms, such as bone pain, fever, weight loss, and night sweats. The symptoms of leukemia can vary depending on the type of leukemia and the stage of the disease.
Can Spread to Other Organs
Leukemia cells can spread from the bone marrow to other parts of the body, including the lymph nodes, spleen, liver, and brain. This is called extramedullary leukemia.
The spread of leukemia cells to other organs can cause a variety of symptoms, depending on the organs that are affected. For example:
- Lymph nodes: Swollen lymph nodes are a common symptom of leukemia. Lymph nodes are small, bean-shaped structures that are part of the immune system. They help to filter out bacteria and other harmful substances from the blood. When leukemia cells spread to the lymph nodes, they can cause the lymph nodes to swell.
- Spleen: The spleen is a large organ located on the left side of the abdomen. It helps to filter blood and remove old or damaged red blood cells. When leukemia cells spread to the spleen, they can cause the spleen to enlarge. This can lead to abdominal pain and discomfort.
- Liver: The liver is a large organ located on the right side of the abdomen. It helps to filter blood and remove toxins from the body. When leukemia cells spread to the liver, they can cause the liver to enlarge. This can lead to abdominal pain, jaundice (yellowing of the skin and eyes), and other symptoms.
- Brain: Leukemia cells can also spread to the brain. This is called central nervous system leukemia. Symptoms of central nervous system leukemia can include headaches, seizures, nausea, vomiting, and changes in vision or hearing.
The spread of leukemia cells to other organs can make the disease more difficult to treat. It can also lead to more serious complications and a worse prognosis.
Leukemia is a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
Many Different Types
There are many different types of leukemia. The most common types are acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). ALL is more common in children, while AML is more common in adults.
Other types of leukemia include:
- Chronic lymphocytic leukemia (CLL): CLL is a type of leukemia that affects mature lymphocytes, a type of white blood cell. CLL is usually a slow-growing leukemia, and many people with CLL do not need treatment right away.
- Chronic myeloid leukemia (CML): CML is a type of leukemia that affects myeloid cells, which are cells that develop into different types of blood cells. CML is usually a chronic disease, but it can be treated with medication.
- Hairy cell leukemia (HCL): HCL is a rare type of leukemia that affects B-lymphocytes, a type of white blood cell. HCL is usually a chronic disease, and it can be treated with medication.
- Large granular lymphocytic leukemia (LGL): LGL is a rare type of leukemia that affects large granular lymphocytes, a type of white blood cell. LGL is usually a chronic disease, and it can be treated with medication.
The type of leukemia that a person has will affect the treatment options and the prognosis.
Leukemia is a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
Can be Treated
Leukemia is a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
- Chemotherapy: Chemotherapy is a type of drug treatment that uses strong chemicals to kill leukemia cells. Chemotherapy can be given orally or intravenously (through a vein). It can be used to treat all types of leukemia.
- Radiation therapy: Radiation therapy uses high-energy X-rays or other forms of radiation to kill leukemia cells. Radiation therapy is often used to treat leukemia that is localized to a specific area of the body, such as the brain or testicles.
- Targeted therapy: Targeted therapy is a type of drug treatment that targets specific molecules on leukemia cells. This can help to kill leukemia cells while leaving healthy cells unharmed. Targeted therapy is often used to treat chronic leukemia, such as CLL and CML.
- Immunotherapy: Immunotherapy is a type of treatment that helps the body's own immune system to fight leukemia. Immunotherapy can be used to treat all types of leukemia.
Stem cell transplant is another treatment option for leukemia. A stem cell transplant is a procedure in which healthy stem cells are taken from a donor and given to the person with leukemia. The healthy stem cells help to rebuild the person's immune system and produce healthy blood cells.
Prognosis Depends on Type and Stage
The prognosis for leukemia depends on the type of leukemia, the stage of the disease, and the overall health of the person.
The type of leukemia is the most important factor in determining the prognosis. Some types of leukemia, such as ALL, have a better prognosis than others, such as AML.
The stage of the disease is also an important prognostic factor. Leukemia is staged from I to IV, with stage I being the earliest stage and stage IV being the most advanced stage. The higher the stage of the disease, the worse the prognosis.
The overall health of the person also plays a role in the prognosis. People who are otherwise healthy are more likely to have a good prognosis than people who have other medical conditions.
In general, the five-year survival rate for all types of leukemia is about 60%. This means that about 60% of people with leukemia will live for at least five years after diagnosis. However, the five-year survival rate varies depending on the type of leukemia and the stage of the disease.
Leukemia is a serious disease, but it is often treatable. The type of leukemia, the stage of the disease, and the overall health of the person will all affect the treatment options and the prognosis.
Most Common Childhood Cancer
Leukemia is the most common childhood cancer. It accounts for about 30% of all childhood cancers.
Leukemia is more common in boys than girls. It is also more common in white children than black or Hispanic children.
The peak age of diagnosis for leukemia is between 2 and 5 years old. However, leukemia can occur at any age.
The most common type of leukemia in children is acute lymphoblastic leukemia (ALL). ALL is a fast-growing leukemia that affects lymphocytes, a type of white blood cell. ALL is usually treated with chemotherapy, radiation therapy, and stem cell transplant.
Leukemia is a serious disease, but it is often curable. The five-year survival rate for children with ALL is about 90%. This means that about 90% of children with ALL will live for at least five years after diagnosis.
