Symptoms of leukemia

Leukemia is a type of blood cancer that begins in the bone marrow, and is the most common cancer among children and teens, accounting for over 30% of cancers diagnosed in young people under 18.

Leukemia starts in white blood cells which normally help fight infections. When you have leukemia, your body makes too many white blood cells, and they aren’t normal. Leukemia cells do not usually form tumors, but they can travel in the blood and reach almost any organ. So, leukemia can cause problems and be found in many different ways, depending on which organs are involved.

Each type of leukemia has specific symptoms that are unique. But there are patterns of leukemia symptoms that appear in nearly all types that include:

Leukemia risk factors & causes

Although the cause of leukemia isn’t known, there are some factors that increase your risk of getting it.

Leukemia types

Leukemia is divided into two major types, acute and chronic, and within those types are subtypes:

Acute: progresses quickly and includes:

• Acute lymphocytic leukemia (ALL) occurs when the body produces a large number of immature lymphocytes. The cancer cells grow quickly and replace normal cells in the bone marrow. ALL prevents healthy blood cells from being made. Life-threatening symptoms can occur.
• Acute myeloid leukemia (AML) is cancer that starts inside bone marrow, the soft tissue inside bones that helps form blood cells. The cancer grows from myeloid cells that would normally turn into white blood cells.

Chronic: progresses more slowly and includes:

• Chronic lymphocytic leukemia (CLL) is cancer of a type of white blood cells called lymphocytes. Cancer cells spread through the blood and bone marrow. CLL can also affect the lymph nodes or other organs such as the liver and spleen. It can eventually cause bone marrow to lose its function.
• Chronic myelogenous leukemia (CML) is cancer that starts inside bone marrow. CML causes an uncontrolled growth of immature cells that make a certain type of white blood cell called myeloid cells. The diseased cells build up in the bone marrow and blood.
• Hairy cell leukemia (HCL) is caused by the abnormal growth of B cells. The cells look hairy under the microscope because they have fine projections coming from their surface. HCL usually leads to low numbers of normal blood cells.
