I have found a lump about the size of a large marble on top of my pubic area.  It isnt noticeable on the outside, its more deep.  I just happened to find it while drying off after a shower.   I had an ultrasound last week for some spotting I had had (which is gone now) and it came back negative.  I also had a kidney infection and a culture was done and it also came back negative.  Just wondering what the lump might be.
Hello! Thank you for the query. This lump is located under the skin and could not be visible in the ultrasound you have had. Most likely it is a benign lesion like lipoma or sebaceous cyst. Both do not cause a cancer. Both can be removed with small incision. To confirm this diagnosis please have soft tissues' ultrasound of this area and consult a surgeon. Hope this will help. Regards.
