Additionally, the rapid development of technological platforms increases the burden on researchers to learn and adapt to new methods. A deep understanding of biological complexity is a prerequisite for interpreting epigenetic data, necessitating profound biological knowledge. The heterogeneity of clinical samples is a common issue that can affect the reliability of research results. Despite these challenges, epigenetics research offers vast opportunities for cancer treatment. In-depth research in epigenetics provides opportunities for the development of precision medicine. Epigenetic analysis of patient samples allows for a better understanding of tumor molecular characteristics, providing a basis for personalized treatment strategies. Epigenetics research is expected to reveal new therapeutic targets, offering new directions for developing more effective anticancer drugs. With the continuous advancement of bioinformatics technology, methods for data integration and analysis are also improving. Integrating epigenetic and genomic data will provide support for a more comprehensive understanding of cancer's molecular mechanisms. The application of new technologies, such as single-cell sequencing and spatial transcriptomics, offers more detailed and comprehensive tools for epigenetic research, potentially addressing some of the technical challenges. 6 Conclusion In the process of cancer development and progression, there is a complex and close interplay between genomics and epigenetics. Mutations and variations in genomics not only directly affect gene sequences but also influence epigenetic modifications. For instance, abnormal changes in epigenetic modifications, such as DNA methylation and histone modifications of cancer-related genes, are often correlated with genomic variations (Zhang et al., 2022), collectively driving tumor development. Epigenetics plays a crucial role in the mechanisms of cancer pathogenesis, influencing gene expression and regulation. Abnormal changes in modifications such as DNA methylation and histone modifications can lead to the inactivation of tumor suppressor genes or the overactivation of oncogenes, promoting uncontrolled proliferation of cancer cells. Additionally, non-coding RNAs, such as miRNAs and lncRNAs, are also involved in the interplay between epigenetics and genomics. They regulate gene transcription and translation levels, affecting the functions and biological behaviors of tumor cells. Personalized treatment strategies targeting specific epigenetic modifications and genomic variations will become a major trend in cancer therapy. By gaining an in-depth understanding of the epigenetic and genomic characteristics of each patient’s tumor, doctors can formulate more precise treatment plans for patients. Further research will help discover more novel therapeutic targets associated with the interplay between epigenetics and genomics. The discovery of these targets will provide new directions for the development of new drugs and therapeutic strategies. With continuous technological advancements, integrative analysis of multi-omics data will become more comprehensive, encompassing more layers of information, and providing deeper insights into the mechanisms of complex diseases. Research on the association between epigenetics and cancer genomics is expected to help identify more specific biomarkers, enhancing the accuracy of early cancer diagnosis and prognosis assessment. The interplay between epigenetics and cancer genomics will drive cancer research and treatment towards deeper and more precise stages in the future. This offers a promising prospect for achieving personalized medicine, precision therapy, and ultimately overcoming cancer.
