Risk Factors
A risk factor is a characteristic, behavior, or condition that increases the possibility of getting a disease. Here are some risk factors for developing myelodysplastic syndrome (MDS):


Age
Your risk for developing MDS increases with age. MDS most often occurs in people over the age of 60.


Gender
Men are at higher risk for developing MDS than women.

Past Chemotherapy or Radiation Therapy
Patients treated with chemotherapy or radiation therapy for other forms of cancer may have an increased risk for MDS.

Radiation Exposure
Exposure to radiation from an atomic bomb or a nuclear accident may increase your chance of developing MDS.

Smoking
Smoking can increase your risk for developing MDS. The carcinogenic toxins in tobacco smoke can get into your bloodstream and spread throughout your body.

Inherited Genetic Disorders
Certain inherited genetic disorders such as Fanconi anemia, dyskeratosis congenita, severe congenital neutropenia, familial platelet disorders and other familial genetic disorders may increase your risk for MDS.


Chemical Exposure
Exposure to benzene, pesticides, fertilizers, and other industrial chemicals may increase your risk for MDS. Exposure to heavy metals such as lead and mercury may also increase this risk.
