What causes multiple myeloma?  I just posted a link to a story about Agent Orange causing blood cancers on  http://www.helpwithcancer.org/.  Multiple myeloma is on that list.  However, except for extreme cases, it is tough to prove a cause and effect relationship between the enviornment and the development of multiple myeloma in specific patients.

In a recent Columbia University study looked at pelvic radiotherapy and the risk of secondary leukemia and multiple myeloma.  are discussed in a report I found on CancerCompass.com:

The researchers concluded: “Pelvic radiation was associated with an increased risk of secondary leukemia but did not appear to increase the risk of multiple myeloma.”

Wright and colleagues published their study in Cancer (Pelvic radiotherapy and the risk of secondary leukemia and multiple myeloma. Cancer, 2010;116(10):2486-92).

These results are not unusual.  Most myeloma experts agree multiple myeloma is primarily a genetic disease.  Where they don’t agree is what triggers the cancer to kick-in and take over.
 
Interesting, but figuring this stuff out is far beyond my pay grade!  I will let brighter minds wrestle with this question.  Feel good and keep smiling!  Pat
