What causes Becker's muscular dystrophy?
Becker muscular dystrophy is very similar to Duchenne muscular dystrophy, except that it gets worse at a much slower rate.
The disorder is passed down through families (inherited). Having a family history of the condition raises your risk.
Becker muscular dystrophy occurs in approximately 3 - 6 out of every 100,000 males. It is less common than Duchenne muscular dystrophy. </s>
