A 22-year-old man presents to his GP, with a lump in his neck

A 22-year-old man presents to his GP, with a lump in his neck. The lump sits above his right clavicle and is around 2 cm in diameter. He first noticed it two weeks ago and it has doubled in size since then. It is not causing any pain. The patient also reports feeling unusually tired and has been having intermittent fevers over the past week. The GP arranges some blood tests and refers the patient for a biopsy of the lump.
