Question: I had CT Scan for throat cancer – can I trust results

Lately with my throat i have been having constant throat clearing and a chronic cough going on for maybe two months now. I have to keep clearing my throat to prevent hoarseness of voice. I had concerns about throat cancer because i use chewing tobacco so was referred to an ENT for further evaluation. The ENT performed a visual inspection of throat, nose and ears (didn’t use a scope or anything), an ultrasound of my thyroid and CT scan of my neck. On the CT scan he noted that that everything appeared normal (statements like spaces of oral floor and neck are clear and well defined, the pharynx and larynx show normal boundaries and normal wall thickness). The only thing that stood out was “there are multiple reactive enlarged lymphadenopathy seen bilaterally, normal neck CT scan otherwise”. Impression of thyroid ultrasound was “essentially normally study”. I can feel one of the enlarged Lymph nodes on the right side of my neck with is non painful and can be pushed it to the point where it can no longer be felt. I keep seeing online that a tube should be passed down the throat for observation. My question is can i trust the results of the CT scan and thyroid ultrasound to have detected some kind of throat cancer or lymphoma and put this fear behind me? I’m 24 years old.
