Will my sex life be affected during treatment for vulvar cancer? what about after treatment?

Vulvar cancer: It depends on how radical would be the treatment (surgery).

Probably yes: Depending on the stage of disease and treatments you will receive , chances are there will be some change in your sex life. Usually not for better, but at times it can be minor changes.

Vulvar cancer: The affect on sex is determined by the amount of tissue that is treated and whether or not the clitoris is involved. You probably have a pre-cancer not an invasive cancer at your age.
