What are the Challenges in Cancer Laboratory Research?
Despite advances, cancer research faces several challenges. One major issue is tumor heterogeneity, where different cancer cells within the same tumor exhibit varied genetic and phenotypic characteristics. This makes it difficult to develop treatments that target all cancer cells effectively. Additionally, replicating the complex tumor microenvironment in vitro is challenging, which can limit the applicability of laboratory findings to clinical settings. Ethical considerations, particularly in the use of animal models, also play a role in research planning and execution.
