Hi, hoping for some reassurance. I've got a lump/ swelling on the back of my right thigh, at the top. It feels about 4cms, almost oval shaped. It's quite soft but doesn't seem to move. It's not painful in any way. I went to the GP and he said he suspects a fatty lump but I've been referred for a scan to rule anything else out. Obviously I've googled and all roads lead to sarcoma, which is naturally very worrying. Any advice/ reassurance would be much appreciated, there will likely be a bit of a wait for the scan!
