Is it true that lymph nodes in the head and neck are not considered swollen and concerning until over 1cm? I have palpable nodes on my left side in the occipital, parotid and supraclavicular region all under 1cm. I’ve seen an oncologist and ENT who’ve told me that they aren’t concerned for those reasons, my age (24), and my completely lack of other symptoms. They say there are too small to accurately do an FNA (we’ve already tried). They’re doing a CT with contrast in a week. Can I trust them?
