What are the Limitations of Biochemical Tests in Cancer?
While biochemical tests are valuable tools, they have limitations. Some of these include:
- Non-Specificity: Some biomarkers can be elevated in non-cancerous conditions, leading to false positives. - Variability: Biomarker levels can vary between individuals and even within the same individual over time, complicating interpretation. - Limited Scope: Not all cancers have well-defined biomarkers that can be reliably measured.
