En malign tumörs stadium är ett mått på hur mycket tumören spritts. Angivelsen av stadiet tar oftast hänsyn till tumörens storlek, hur djupt den har trängt in, om den har invaderat angränsande organ, hur många lymfkörtlar den har spritt sig till (om några), och om den har metastaserat till längre bort belägna organ. Stadiebestämning av tumörsjukdomar är viktigt eftersom stadiet vid diagnostillfället är den viktigaste prognostiska faktorn för överlevnad och eftersom beslutet om behandlingen ofta grundar sig på information om sjukdomens stadium.
