Ear cancer - just found out I have a tumour in my ear. Don't know if it's cancerous yet but I'm terrified to find out. I'm only 20 years old

Went to the ent today and just found out I have a tumour in my ear. To be honest I don’t know whether it’s cancerous or not but I’m terrified to find out. My family thinks of the worst outcome which safe to say it’s not the best thing to hear about but then again coming to reality that It might actually be cancerous. I’m 20 year old guy but I just don’t know how to cope with these feelings, sometimes I just wanna burst out crying but I’m holding it in.
