Morning @TripleTea,
Sorry to hear that you have to do this thing again. Gutted I am sure is an understatement. It doesn not necessarily mean it has gone any further than that. Have you had a CT or anything?, I had a lump in my armpit which was the only way I found the thing at all. They did an axillary clearance and removed all the lymph nodes. There ended up being 5 positive ones and the rest were clear. Fingers and toes crossed for you lovely that it has stayed put in the nodes.
