biopsy-proven malignancy
A cancer diagnosis confirmed through histopathological examination of tissue samples obtained via biopsy.
Full Definition
A definitive cancer diagnosis that has been established through microscopic examination of tissue samples by a pathologist. This represents the gold standard for cancer diagnosis, distinguishing it from presumptive diagnoses based solely on imaging or clinical findings. In screening contexts, this term indicates that a suspicious finding has progressed through the diagnostic workup to confirmed malignancy. The distinction is crucial for reporting screening program outcomes and calculating positive predictive values.
Usage
Usage note: Always hyphenate when used as a compound modifier before a noun.
