Cancer is an uncontrolled growth of abnormal cells. It doesn't come and go nor does it stop once it starts.

I agree with the others. You've already been to an ENT, been scoped and diagnosed you with acid reflux. In eight months, you would be showing more signs and symptoms. In the few months from when I noticed a node on my neck, it was quite apparent something was going on. The ENT knew right off it was sinister. A FNAB confirmed it.

There's a little more going on than meets the eye concerning your personal relationship which I feel is rearing it's head. Certainly you can chase a diagnosis and perhaps for your own peace of mind and reassurance you should, but if there's nothing to biopsy then it's a mute point.

Dr. Google will tell you a pimple is skin cancer so stay off the search engines. What I sense here is a bit of anxiety and guilt more than cancer.

Hope all works out for you.
