What causes chronic lymphocytic leukemia (CLL)?

ANSWER

In most cases, doctors don't know what causes CLL. You're more likely to get it if:

If you were exposed to Agent Orange, an herbicide widely used during the Vietnam War, your chances of getting CLL may also be higher.

  • You have a parent, sibling, or child who has CLL.
  • You're middle-aged or older.
  • You're a white man.
  • You have relatives who are either Eastern European or Russian Jews.
