Hereditary Cancer Risk, Diagnostics, and Treatment Strategies Practice Test

Precise Tumor testing is used to identify genetic changes in a tumor that can be targeted with specific therapies, guiding personalized treatment. This approach is most clearly indicated when a patient has advanced cancer and needs targeted therapy options, because finding actionable mutations or gene alterations can directly inform which targeted drugs might work. In early-stage cancer, screening decisions rely more on detection and local treatment plans rather than profiling the tumor’s mutations for drug choices. For a benign tumor, genetic testing isn’t typically used to plan surgery since there aren’t malignant drivers to target. An infectious disease scenario involves pathogens, not tumor cells, so tumor genetic testing wouldn’t apply.
