Hi Bijou.
The lesions by themselves don’t necessarily indicate you have myeloma. That’s why other tests are required to confirm it’s myeloma.
Treatment, if you have myeloma, will be given if you fulfill certain criteria it’s called CRAB I think it stands for Calcium, Renal, Anaemia and Bones. If you don’t fulfill the criteria you may not need to have treatment and you may be classed as having smouldering myeloma which means though you have myeloma it’s not causing any problems and can be left untreated until it starts causing problems if it ever does. Some smoulder for years without ever needing treatment.
The lesions could be Plasmacytoma and will probably be treated with radiotherapy.
They can’t treat you till they get the diagnosis right. I can understand your frustration but getting the right treatment, if it’s necessary, is key.
By the way we don’t stage myeloma in the UK.
Every day is a gift.
