What Are the Challenges in Biomarker-Driven Cancer Treatment?
Despite their promise, there are challenges in the application of biomarkers in cancer treatment. One major issue is the heterogeneity of tumors, which can lead to variations in biomarker expression within and between tumors. Additionally, the cost and complexity of biomarker testing can limit accessibility. There is also a need for continuous research to discover new biomarkers and improve existing ones.
