Lipomas are the most common type of benign, soft tissue tumor. The growths generally develop between the skin and the muscle below, corresponding to where fat grows in the soft tissue. Though mostly harmless, lipomas can be painful and should be examined by a doctor if the individual is concerned or if the tumor is growing rapidly.
Though experts are unsure what specifically causes lipomas, they have identified several risk factors, one of which is genetics. Lipomas tend to run in families, and a family history of the growths could increase a person's chance of developing them.
