Enlarged Tonsil

Good evening. 
 

I just wanted to hear from anyone that has been diagnosed with cancer of the tonsil. Would like to know your experience of symptoms/ getting diagnosed etc if you are willing to share. 
 

I have been unwell recently, having trouble swallowing etc. Wasnt until now that I discovered that having one enlarged tonsil is concerning? Ive had it for a few years now but i just thought it was normal after my last time having tonsillitis. 
 

I spoke to the doctor today, and they are referring me for a scan. hve any of you had scans to test/diagnose? From looking online it suggests a biopsy is needed. 
 

would be greatful for any replies. Thank you
