Which of the following is a risk factor for Multiple Myeloma?

• A. Increased age
• B. Regular exercise
• C. Low-salt diet
• D. Young age

Answer: (A)

Increasing age is the risk factor here. The development of multiple myeloma strongly correlates with getting older, with most cases occurring in people in their 60s and 70s. As people age, there’s more cumulative genetic damage in plasma cells and a higher chance of precursor conditions like MGUS progressing to myeloma, along with changes in the bone marrow environment that support malignant plasma cell growth. Those factors together make age the main driver of risk.

Regular exercise tends to be protective or neutral for many cancers and isn’t linked as a risk factor for multiple myeloma. A low-salt diet isn’t an established risk factor for this disease, and younger individuals have a lower risk compared with older adults.
