A cell mutation is a change in the DNA — the instruction manual that tells your cells how to behave. Normally, genes act like brakes, keeping cell growth orderly and controlled. When those genes mutate, the brakes can fail, allowing cells to divide too quickly and in an uncontrolled way. In myeloma specifically, mutations occur in plasma cells — white blood cells that live in the bone marrow. These mutated plasma cells:

- Divide too quickly, making too many copies of themselves
- Stop dying when they should
- Crowd out healthy blood cells in the bone marrow
- Produce abnormal proteins called M proteins, which can damage organs like the kidneys and bones Mutations can build up over time due to factors like radiation exposure, certain chemicals, or simply errors made during normal cell division. The older we get, the more mutations our blood cells tend to collect — which is one reason myeloma is more common in older adults.

It's also worth knowing that in myeloma, mutations can continue to develop over time, which is why the disease can sometimes become resistant to treatments that previously worked well.
