A middle-aged man presents as he has been unwell for several months and has lost 5 kg in weight. What are the differential diagnoses and how would you manage this patient?
Bill is a 45-year-old man whom you do not know well, although you have seen his family frequently. He has ‘never been ill before’ and is taking no medications. His wife has been urging him to see you because he has been unwell for several months. When he finally does see you, he tells you he has lost 5 kg in weight over the past three months, but he has no other symptoms he can think of.
