Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the white blood cells in the body. It is a slow-growing cancer that can cause serious health problems if not treated. While it is not curable, there are treatments available that can extend life expectancy and improve quality of life for those living with CLL.
What Causes CLL?
CLL is caused by an abnormality in the DNA of the white blood cells, which causes them to divide and grow uncontrollably. The exact cause of this abnormality is unknown, but it is believed to be linked to genetic factors and environmental exposures.
Who is at Risk for CLL?
CLL is most common in people over the age of 55, and is more common in men than women. Other risk factors include a family history of CLL, certain genetic disorders, and exposure to certain chemicals or radiation.
What are the Symptoms of CLL?
The most common symptoms of CLL are fatigue, weight loss, night sweats, and swollen lymph nodes. Other symptoms may include fever, chills, and an enlarged spleen or liver.
How is CLL Diagnosed?
CLL is usually diagnosed through a combination of a physical exam, blood tests, and imaging tests. A bone marrow biopsy may also be used to confirm the diagnosis.
How Serious is CLL?
CLL is a serious condition that can cause serious health problems if left untreated. In some cases, the cancer can progress to an advanced stage that is more difficult to treat. However, with proper treatment, most people with CLL can live for many years with a good quality of life.
