Radiation therapy has been, and is being used in treatment of patients with keloid. Radiation
is typically used as an adjunct to surgery in order to reduce the recurrence rate of keloid.
Radiation therapy is not free of long term side effects. Radiation Therapy is known to cause
secondary cancers. The investigators also do not have a good understanding as to how
effective radiation therapy is in preventing recurrence of keloid.
Purposes of this study are to determine the long term safety as well as efficacy of radiation
therapy when used for treatment of keloid.
