Study summary

The purpose of this research study is to investigate the possibility that a topical drug could restore nipple sensitivity and improve sexual quality of life in breast cancer survivors.

Read the detailed description

Approximately, 80% of breast cancer survivors undergoing will suffer from a permanent reduced reduction in nipple sensitivity and associated lowerdecrease in sexual quality of life. Currently, there are no treatments for restoring nipple sensitivity and the associatedto improve lower sexual quality of life this condition. It would thus be of great clinical benefit to post breast surgery patients if a provide a new safe and , effective , topical , on-demand, treatment for this condition can be developed.
