I completely, absolutely, and totally agree that you should get a needle biopsy. It will give you the piece of mind your urgently looking for.
That being said, right after radiation concluded, I had a hard lump in the back of my neck. I freaked out, and I was positive it was cancer. Turns out it was my body freaking out over all the fun and games in itself.
Regardless, it just doesn't make sense to skip a needle biopsy. It's available, I assume relatively painless, and it'll calm you down. What's the harm?
