Hairy cell leukemia may be caused by mutations in the BRAF gene and exposure to radiation and pesticides.


Causes of Hairy cell leukemia may include:[1][2][3]

  • Genetic mutations are the most common causes of hairy cell leukemia
  • radiation exposure
  • Pesticide exposure
  • HLA haplotype, which is sharing among family members
