Some people are diagnosed with myeloma that has no symptoms. This is sometimes called smouldering myeloma or indolent myeloma. It is usually diagnosed after a routine blood test and does not need treatment straight away.
There is also a type of myeloma called light chain myeloma, or Bence Jones myeloma. The myeloma cells make too many light chains. This type of myeloma does not make an abnormal paraprotein.
A rare type of myeloma, called non-secretory myeloma, produces few or no immunoglobulin chains.
