Question??? Has anyone else had something like this??

I have developed a "new" problem, or I think it is potentially a problem. I have not mentioned it here, but now it is really beginning to scare me. About 3 months ago, I began to notice that it felt like I had a "lump" on my left lower abdomen. It kind of felt almost like it was "swollen". My right side is flat completely, so I noticed it because it was so puffy and my right side under the pain pump is so flat. I've been to the doctors, and even my PCP since it came up and I did not say anything. I have kind of blown it off until the past few days. Now it seems to be an oval lump that is getting larger I think. It seems to be protruding out more away from my abdomen and I can see it plainly in the mirror. Jim said he sees it also, so it has gotten bigger. I really don't know what to do. I have researched it, and it could be a number of things. I think I am just fearful about seeing the doctor about it... so I have just not said anything... has anyone else had something like this???
