Risk Factors
A risk factor is a characteristic, behavior, or condition that increases the likelihood of getting a disease. Here are some risk factors for developing CLL:
Age
Your chance of developing CLL increases with age. Most people who develop this disease are over the age of 60.
Family History
First-degree relatives of a person with CLL have at least twice the risk of developing CLL due to inherited genetic changes.
Gender
Men are at a slightly higher risk for developing CLL than women.
Race/Ethnicity
CLL is more common in Caucasians (whites) than in African-Americans or people of other races.
Chemical/Radiation Exposure
Exposure to some chemicals may increase your risk for CLL. Previous treatment or exposure to external radiation therapy may also increase this risk.
