Summary

This study compares two standard treatments for early-stage larynx cancer: laser surgery and a newer, more precise radiation therapy that targets only the affected vocal cord. The main goal is to see which approach better preserves voice quality over two years. About 34 adults with stage 0 or I glottic cancer will be randomly assigned to one of the treatments and will report their voice function using a questionnaire.
