Positive family history, exposure to radiation and to minerals like zeolite, and some rare viruses are also said to be responsible for the cancer though the instances are extremely rare. The genetic mutation is obviously the major reason for any cancer to develop but asbestos exposure forms the major risk factor for such things to occur in the body.
