It's rather embarressing, but for about a year now I have had a lump in the right side of my vulva. It has not changed in size since I discovered it, and it is not painful. I think it might be a benign tumor, but I'm not certain. I doubt it's cancer, but I just want to be cautious because my aunt has had cervical cancer and my grandmother had to have a hystorectomy because of ovarian cancer. What should I do?
