I can understand your concern. You may have some benign cyst lie Catholic cyst or some soft tissue tumor arising from vagina or vulva. Chances of cancer are less likely. Still you should go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health. </s>
