SEER Stat Fact Sheets: Chronic Lymphocytic Leukemia (CLL)
Statistics at a GlanceShow More
At a Glance
- Estimated New Cases in 2015 14,620
- Estimated Deaths in 2015 4,650
Number of New Cases and Deaths per 100,000: The number of new cases of chronic lymphocytic leukemia was 4.5 per 100,000 men and women per year. The number of deaths was 1.4 per 100,000 men and women per year. These rates are age-adjusted and based on 2008-2012 cases and deaths.
Lifetime Risk of Developing Cancer: Approximately 0.6 percent of men and women will be diagnosed with chronic lymphocytic leukemia at some point during their lifetime, based on 2010-2012 data.
Survival StatisticsShow More
How Many People Survive 5 Years Or More after Being Diagnosed with Chronic Lymphocytic Leukemia?
Relative survival statistics compare the survival of patients diagnosed with cancer with the survival of people in the general population who are the same age, race, and sex and who have not been diagnosed with cancer. Because survival statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. No two patients are entirely alike, and treatment and responses to treatment can vary greatly.
Based on data from SEER 18 2005-2011. Gray figures represent those who have died from chronic lymphocytic leukemia. Green figures represent those who have survived 5 years or more.

|Chronic Lymphocytic Leukemia||14,620||4,650|
Chronic lymphocytic leukemia represents 0.9% of all new cancer cases in the U.S.
In 2015, it is estimated that there will be 14,620 new cases of chronic lymphocytic leukemia and an estimated 4,650 people will die of this disease.
Who Gets This Cancer?
Chronic lymphocytic leukemia is more common in adults and more common among men than women, particularly white men. The number of new cases of chronic lymphocytic leukemia was 4.5 per 100,000 men and women per year based on 2008-2012 cases.
Chronic lymphocytic leukemia is most frequently diagnosed among people aged 65-74.

Who Dies From This Cancer?
Death rates from chronic lymphocytic leukemia are higher among older adults, or those 75 and older. People with leukemia have many treatment options, and treatment for leukemia can often control the disease and its symptoms. The number of deaths was 1.4 per 100,000 men and women per year based on 2008-2012 deaths.
The percent of chronic lymphocytic leukemia deaths is highest among people aged 75-84.

Changes Over Time
Keeping track of the number of new cases, deaths, and survival over time (trends) can help scientists understand whether progress is being made and where additional research is needed to address challenges, such as improving screening or finding better treatments.
Using statistical models for analysis, rates for new chronic lymphocytic leukemia cases have not changed significantly over the last 10 years. Death rates have been falling on average 1.3% each year over 2003-2012. 5-year survival trends are shown below the figure.

Cancer and the Blood
Leukemia is cancer that starts in the tissue that forms blood. Most blood cells develop from cells in the bone marrow called stem cells. In a person with leukemia, the bone marrow makes abnormal white blood cells. The abnormal cells are leukemia cells. Unlike normal blood cells, leukemia cells don't die when they should. They may crowd out normal white blood cells, red blood cells, and platelets. This makes it hard for normal blood cells to do their work. The four main types of leukemia are:
- Acute lymphoblastic leukemia (ALL)
- Acute myelogenous leukemia (AML)
- Chronic lymphocytic leukemia (CLL)
- Chronic myelogenous leukemia (CML)

This factsheet focuses on population statistics that are based on the US population. Because these statistics are based on large groups of people, they cannot be used to predict exactly what will happen to an individual patient. To see tailored statistics, browse the SEER Cancer Statistics Review. To see statistics for a specific state, go to the State Cancer Profiles.
The statistics presented in this factsheet are based on the most recent data available, most of which can be found in the SEER Cancer Statistics Review. In some cases, different year spans may be used. Estimates for the current year are based on past data.
Cancer is a complex topic. There is a wide range of information available. This factsheet does not address causes, symptoms, diagnosis, treatment, follow-up care, or decision making, although it provides links to information in many of these areas.
