Wow … this has come up from an old comment and I can tell you with all certainty to explore anything that might be worrying you.
I had a lump in my neck that was diagnosed as nothing… until 4 months later and it came back and was told that I had throat cancer that had moved to my lymph glands… which, unfortunately, means your into metastatic cancer territory.
Mine was inoperable due to it being wrapped around my carotid artery.
Trust me… if you are worried take every option available to be sure.
You’re welcome to PM me at any time.
