The chances of smoldering multiple myeloma (SMM) progressing to active multiple myeloma vary over time:

- First 5 Years: About 10% of people with SMM develop multiple myeloma each year
- 5 to 10 Years: About 3% of people develop multiple myeloma each year.
- 10+ Years: About 1% of people develop multiple myeloma each Show Full Answer

The chances of smoldering multiple myeloma (SMM) progressing to active multiple myeloma vary over time:

- First 5 Years: About 10% of people with SMM develop multiple myeloma each year.
- 5 to 10 Years: About 3% of people develop multiple myeloma each year.
- 10+ Years: About 1% of people develop multiple myeloma each year.

Certain risk factors can increase the likelihood of progression, including:

- Plasma cells with specific gene changes.
- High numbers of plasma cells in the bone marrow.
- High levels of M protein.
- Increasing M protein levels over time.
- M protein made from IgA heavy chain, rather than IgG.
- Bone lesions visible on X-rays.
