Myeloma receives a lot less attention (and funding) than other more well known cancers. Please make a donation to one of the following charities it really will make a difference.
In the U.K.:

Donate Myeloma UK Do a great job of supporting myeloma patients as well as funding research into myeloma
In the U.S.:
Donate MMRFAre a key source of funding for research into myeloma

The donation forms also allow you to enter Memorial/Tribute information. If you could make the donation in memory of Margaret Johnson (my mum), it will help me to track them.

Also if you are in the UK remember you may be able to gift aid your donation, allowing the charity to claim the tax back.
