hEHello out there. My name is Nancy Bush (shortshot80,net) I arrived on the Mayo Clinic site because I have 2 types of Lung Cancer. My son who will be 62 in August has been diagnosed with Jak 2 a little over a year ago. He has since been unable to work in his profession ( Plaster Contractor. Some one told him that perhaps this could have been contracted by "radiation". What causes this disease? Is there anything he can do besides take this "(Hydroxyurea caplets? His body hurts all the time and his doctor tells him that he isn't supposed to have any pain... But he does and cannot get any pain pills. At this time he doesn't have any money/insurance to go to another doctor. Also just some information ## son's second wife has lung cancer mastized to her lymph nodes. and his first wife died of "melanomah". Any answers would be appreciated.. Nancy
