cystic

This term is strictly clinical and carries a heavy medical weight. It describes a structural state where tissues are replaced by fluid-filled sacs, evoking an image of pockets or bubbles within an organ rather than a solid mass. In a diagnostic setting, it differentiates a lesion from a solid tumor. While a solid growth is often viewed as a dense invasion, a cystic growth is perceived as a hollowed-out or fluid-containing anomaly, which often changes the surgical approach or the prognosis for the patient.
