Hello. A couple of years ago I noticed a solid growing lump on my neck after having glandular fever/ chronic tonsillitis and over the past few months I have had symptoms that indicate lymphoma (fatigue, weight loss, night sweats, many more). I have been seen by ENT which consisted of an ultrasound. I was told it was just a reactive lymph node which should go in a couple a weeks to a month; which it hasn't. My concern is that because I am still young I fear that doctors often don't take me seriously (and I am autistic so find it hard to explain problem). Also on the NHS it says that the only way to diagnose lymphoma is by having a biopsy which I was declined in having.
Very confused of how the diagnosis of it all works and whether or not I should be advocating for myself or if I shouldn't worry.
