The future of proteomics in cancer looks promising with advancements in technology and methods. Improved mass spectrometry instruments, better sample preparation techniques, and advanced bioinformatics tools are expected to enhance the sensitivity, accuracy, and throughput of proteomic analyses. Integration of proteomics with other omics data, such as genomics and transcriptomics, will provide a more comprehensive understanding of cancer biology and lead to the development of more effective diagnostics and therapies.
