While<unk> s are present in both the various body areas of males and females, one study discovered that these tumors were more likely to occur in Caucasian males.<unk> s can be found in a widespread age of people ranging from 18 to 79 years old. Most of these tumors are not spotted until about the 30s. This asymptomatic nature is due to the fact that a majority of<unk> s grow silently and are sometimes dormant without causing any pain. This is what contributes to the difficulty of catching<unk> s. These benign tumors can grow up to 5.0 centimeters (most of them range around to 2.0 cm). Although<unk> s are not known to infiltrate surrounding tissues, it is possible that there are multiple<unk> s in the same area.
