Cancer biomarkers are biological signs that can be used to diagnose and track the illness, possibly leading to early diagnosis and personalized therapy regimens. Improving patient outcomes requires the development and verification of novel biomarkers, but this is usually an arduous and costly procedure. Collaborative initiatives that use big data and interdisciplinary methods are essential to accelerating the discovery of biomarkers. These operations can potentially improve the integration of biomarkers into clinical practice and streamline the validation process.
