Great news on the no growth!
I was interested to hear you have another lump on the back of your neck, same side. I had a benign tumour in one of my parathyroid glands (removed in 2003), same side as my AN. It was tucked just under my chin - awfully close proximity IYAM. I also have skin tags, moles and a few skin lumps (about 2-3 mm in size) on my body. About 90% of them are on the same side as my AN, mostly clustered along my neck and collar bone. It makes me wonder why they are all clustered in that part of my body.
My acupuncturist (who's also PhD and MD) told me that *all* people have benign/non-cancerous lumps and tumours, usually internally where we can't see them. He says that our bodies are built with a tremendous amount of "back-up" to crucial systems, so these tumours rarely affect any kind of functioning. For example, you can live with only one functional kidney, but we're born with two. So having a lump or two in your kidney's is not going to take away from your health.
It's interesting to think about. Whenever a new mole or skin tag or lump appears, I start off by disliking it and wishing it didn't exist. But eventually I come to accept it, and treat it lovingly, as a natural part of my body. I try to think of my AN in the same way - it's a natural part of me , not some hideous invader.
