I am glad I am precautious and annoying. The lump in my arm popped up about two years ago and stayed unangry for two years until it started to grow and hurt. I had it removed as it was interfering with my writing and typing. It came back again and I knew something was wrong. I called my surgeon, whom luckily is also a surgical oncologist. I did not get to see her and her resident dismissed it as carpal tunnel syndrome. It seemed logical until her assistant called last week to book me in for a follow up appointment. They had sent the lump to Toronto as it had unclear margins. What was a lipoma is not a lipoma. It is a soft tissue tumour, it may be a Nerve Sheath tumour. Things are starting to make sense. Like the edema, the cafe au lait spots which they thought were nigericans. The outlook is optimistic if they can get all the tissue out I might be good. However it might be bad.
