    Le lesioni serrate sono polipi del colon caratterizzati da una struttura microscopica a denti di sega. A differenza dei classici polipi con il gambo, queste formazioni sono spesso piatte e silenziose, rendendole estremamente difficili da individuare durante una normale endoscopia. Come spiegano Lena e Miles, queste lesioni giocano a nascondino e richiedono un occhio clinico molto attento per non essere ignorate durante i controlli di routine.

    Uno degli aspetti più pericolosi delle lesioni serrate è che spesso non presentano alcun sintomo evidente. Miles sottolinea che queste formazioni non sanguinano quasi mai e non causano dolore, portando molti pazienti a rimandare i controlli pensando di stare bene. Spesso vengono scoperte solo per caso durante esami effettuati per altri motivi, rendendo la prevenzione attiva l'unico strumento efficace per individuarle prima che evolvano.

    Sebbene molte lesioni serrate non siano inizialmente displastiche, sono considerate precursori subdoli del cancro. Esse rappresentano una via alternativa allo sviluppo del carcinoma del colon attraverso quella che i medici definiscono instabilità dei microsatelliti. Anche se sembrano inizialmente benigne, il loro potenziale evolutivo le rende estremamente pericolose, poiché possono trasformarsi in forme tumorali senza mostrare i segnali d'allarme tipici di altre lesioni intestinali.
