Causes of leukemia

While the exact cause is not known, the following risk factors may play a role in its development.

  • Side effect of previous radiation or chemotherapy for other types of cancers
  • Genetic disorders like Down syndrome, or family history 
  • Repeated and excess exposure to the chemical benzene, found in cigarette smoke
  • Smoking, which increases your risk of developing acute myeloid leukemia (AML)
  • Blood disorders such as myelodysplastic syndrome

Types of leukemia

  • Acute lymphocytic leukemia (ALL)

It is one of the most common types of leukemia in children. It may spread to your central nervous system and lymph nodes. This type can progress quickly.

  • Acute myelogenous leukemia (AML)

AML is the second most common form of leukemia in children and the most common in adults. It may affect red, white blood cells and platelets.

  • Chronic lymphocytic leukemia (CLL)

This is also one of the most common types. It is more prevalent in adults over 65, especially men. It starts in white blood cells known as B cells and progresses slowly. 

  • Chronic myelogenous leukemia (CML)

CML is an uncommon type and progresses slowly. It mainly affects older people and is a result of chromosome mutation. The cause of this mutation is not yet known, and its diagnosis is only done with the help of blood work.

Leukemia treatment

Chemotherapy

This is the main type of leukemia treatment and uses prescribed drugs to kill its cells. Depending on the type, your treatment may include either a single drug or a combination of drugs. You may get the drug in the form of pills or intravenous injection.

Immunotherapy

This form of treatment uses your body’s immune system to fight leukemia. Sometimes, your immune system may not locate and attack cancer cells that remain hidden with the help of the protein they produce. Immunotherapy interferes with this process.

Targeted therapy

Here the treatment focuses on a specific abnormality present in cancer cells. These cells may start to die when treatment blocks these abnormalities. Doctors measure its effectiveness by testing its cells.

Stem cell transplant

Its treatment replaces your diseased bone marrow with a healthy one. This is why it is also known as bone marrow transplant. It can take place in two forms, the first being autologous transplantation. This is where your own bone marrow is the replacement marrow. The other one is allogeneic transplantation. It is when a donor’s bone marrow replaces your own.

Clinical trials

These experiments help determine the efficiency of new cancer treatments. They also allow doctors to find new ways to use existing treatments more effectively. Before opting for this as treatment, talk to your doctor about benefits and risks.

Radiotherapies

Also known as radiation therapy, this leukemia treatment method uses high-energy radiation. This helps damage and stop the growth of cells. The radiation may focus on the entire body or a specific area.
