No. The non type is actually a catch all for around 60 other types. It's a real name though, and it's known for being unwieldy.

No but there's a grain of truth. I'm not a doctor but here's what I remember from Wikipedia and watching medical dramas.

Hodgkin's is named after a doctor but its a specific type of lymphoma that makes up something like 10% of all lymphoma cases and usually follows a predictable pattern. I believe it has a higher survival rate than most cancers, especially in younger people.

Non-Hodgkin's lymphoma includes every other subtype of lymphoma. I know there are 2 major subsets of subtypes and that there are dozens of subtypes.

No it's not true, sadly
