Multiple myeloma is a type of cancer that many people have never heard of. Unlike cancers that are composed of solid, palpable tumors, multiple myeloma affects white blood cells. As cancerous plasma cells replicate in the bone marrow, it can become harder for a person's healthy white blood cells to produce vital infection fighting antibodies. Onset of multiple myeloma typically happens later in life. For patients with slow growing disease, often times monitoring suffices for a period of time. For patients that are symptomatic (bone pain, nausea, weight loss, infections) and require treatment, there are a variety of options to slow progression of this relatively rare disease. The type of therapy recommended is based on the location of the myeloma and degree of systemic spread.
