One-size treatment for blood cancer probably doesn't fit all, researchers say

Though African-American men are three times more likely to be diagnosed with a blood cancer called multiple myeloma, most scientific research on the disease has been based on people of European descent. That trend is problematic considering that African-Americans -- the most at-risk population for multiple myeloma -- have different genetics that can affect how this type of cancer progresses and what kind of targeted therapies are most effective.
