Hi Sallyann
When I was diagnosed with a plasmacytoma, I also had no clue what I was dealing with. I think there is a Leaflet on the Site about them, but before I knew about MUK I track
Led the Internet frantically like you.
Plasmatomas are cellular masses formed by rogue cells. They either form as lumps in the tissues, (sounds like what Daz has. Is it around his throat/shoulder area?). They can also form around bones. In my case it formed around one of my vertebrae and caused restriction of the spinal cord. This meant I temporarily lost all mobility. I had to have an operation to remove the growth and had 10 fractions (sessions) of radiotherapy as soon as my back had healed. This was three months after original diagnosis. Diagnose of Myeloma followed diagnosis of plasmacytoma by about a month (following a bone marrow biopsy.)
Which hospital is Daz under? Can he change. Someone on here is under Hull and I think they find it OK.
This isn't a death knell, so keep strong for one another.
