Despite significant advancements, there are several challenges in the field of cancer genomics:
1. Tumor Heterogeneity: Tumors can be highly heterogeneous, with different cells exhibiting distinct genetic profiles. This complicates the analysis and treatment of cancer. 2. Data Interpretation: Interpreting the vast amount of data generated by genomic studies is complex and requires advanced computational tools and expertise. 3. Accessibility: High costs and limited access to advanced sequencing technologies can hinder widespread adoption of genomic approaches in clinical practice.
