I can feel your anxiety and I imagine every person on this site knows what it's like to wait and wonder. But we also know from experience that cancer is a highly variable thing and it is often not helpful to make comparisons with other people or other symptoms. I made the common mistake of googling my symptoms (I didn't find a lump) and scared myself with possibilities that never happened. When you get your results, and IF there is a malignancy, you will be assisted to know who to see and what your treatment options will be. A family history of cancer may be a factor, but it may also not be a significant one. The links that the very helpful @soldiercrab has provided will help your preparation, but waiting until Tuesday is unfortunately what has to be done right now. As others have suggested, you need as much distraction as possible till then. Here's hoping for good news.
