We don’t just support people with myeloma, we’re also here for people with related conditions. Find out about conditions related to myeloma and the different effects they can have on your body.

There are a number of conditions related to myeloma. They are similar to myeloma in how they develop and/or the cells they affect. Some of these, like AL amyloidosis and solitary plasmacytoma, you can have alongside a diagnosis of myeloma. Others, like MGUS and smouldering myeloma, can sometimes develop into myeloma.

AL amyloidosis

A disease in which abnormal proteins are deposited in the tissues and organs of the body, causing damage.

Smouldering myeloma

A very slow-growing type of myeloma. Sometimes known as asymptomatic myeloma.

Monoclonal Gammopathy of Undetermined Significance (MGUS)
