Summary
Brief summary (as posted)
This trial seeks to determine if therapy with a CO2 laser to the vagina is more effective than lidocaine to the opening of the vagina before intercourse to reduce painful intercourse in women who are breast cancer survivors. This study will also be looking at whether or not the CO2 laser improves pelvic floor function, bowel and bladder function, and sexual function before and after treatment.
