There are members of various forums who mention chronic stress possibly contributing to a myeloma diagnosis.  Telomerase has been discussed in this forum as a form of therapy.  The article linked below furthers this discussion.  David  

"Immune cells end in protective caps, called telomeres, that are shorter
in persons suffering chronic stress. Shortened telomeres are a sign of
premature aging. A new UCLA study suggests that the stress hormone
cortisol is the culprit behind telomeres' early aging and offers a
potential drug target for protecting the immune system against the wear
and tear of long-term stress."
