Thank you Angie for responding.

It ended up that I didn't see the consultant, I saw the cancer nurse.  She said the results had come back clear (which is obviously great news).  I told her about the lump and she just looked at my leg and said oh its just where the stitches have been pulled (theres a podgy bit sticking out now where they've taken the chunk out).  I told her it wasn't that bit and it was an actually lump so she had a quick prod and said its likely to be scar tissue.  Fingers crossed that is the case, I will just keep an eye on it.

Glad that I'm all clear but not feeling the relief I was expecting.  I know I'm very lucky as it was caught so early but feel quite apprehensive that I'll get another.  I'm sure it all just needs to sink in a little as its all been very quick!  

Thanks again
