Cancer survivors can be affected by a number of health problems, but often their greatest concern is facing cancer again. Chronic lymphocytic leukemia (CLL) is seldom cured, but it can often be treated and controlled for a long time. During this time, some people with CLL may develop a new, unrelated cancer later. This is called a second cancer.
Unfortunately, being treated for cancer doesn’t mean you can’t get another cancer. People who have had cancer can still get the same types of cancers that other people get. In fact, certain types of cancer and cancer treatments can be linked to a higher risk of certain second cancers.
People with CLL can get any type of second cancer, but they have an increased risk of:
People with CLL need to see their doctors regularly. Let your doctor know if you have any new symptoms or problems. These may be from the CLL, or they may be from some other cancer or disease. Also be sure to get your routine cancer screening tests and well check-ups. These can help find problems early, when they're usually easier to treat.
All people with CLL should avoid tobacco smoke, as smoking increases the risk of many cancers and might further increase the risk of some of the second cancers seen in patients with CLL.
See Second Cancers in Adults for more information about causes of second cancers.
