Multiple myeloma also known as plasma cell myeloma or Kahler's disease .It is a cancer of plasma cells, a type of white blood cell normally responsible for producing antibodies. In multiple myeloma, collections of abnormal plasma cells accumulate in the bone marrow, where they interfere with the production of normal blood cells. Bisphosphonate treatment is often started along with chemo. If the areas of damaged bone continue to cause symptoms, radiation therapy may be used.
Differences in the prevalence of multiple myeloma across races have been observed, with a two- to three-fold greater prevalence in African Americans compared with Caucasians. Little is known about the incidence or prevalence of multiple myeloma in other populations. The association between father's country of origin and the incidence of multiple myeloma was examined in a nationwide population-based cohort. Health-related data on 746 200 16-19-year-old Jewish males examined between 1967 and 1998 were linked to the Israel National Cancer Registry to derive multiple myeloma incidence up to 2006.
