What it is
Lymphoma memory hook: Hodgkin is the "nicer" one. It stays localized. It spreads contiguously, which means node to next-door node. It shows Reed-Sternberg cells, hits younger adults, and has a better prognosis, or outlook. Non-Hodgkin is diffuse and scattered. It jumps around (non-contiguous, extranodal), hits older adults, and has a worse prognosis.
