i have a lump on the lip of my vagina.it is about the size of a pea i have it 8 years.i noticed it after i had my baby.a few months ago it got bigger just a little bit. i could feel it when i wiped myself.i went to the doctor and she sent me to a guynacolagis and she told me it was a cist.and told me to squeeze it in the bath.i have tryed but it just moves around and i cant get anything from it.could this b cancer?
