b. gender.

The rationale for leaving a 1-cm to 3-cm strip of skin and soft tissue rather than total circumferential irradiation of an extremity being treated for STS is that it: a. decreases excessive erythema. b. promotes healing of the incision scar. c. avoids future excessive fibrosis and edema. d. increases future mobility for the treated limb.
