The future of GWAS in cancer research looks promising. Advances in genomic technologies and data analysis methods are likely to improve the power and resolution of GWAS. Integrating GWAS data with other types of genomic data, such as transcriptomics and proteomics, can provide a more comprehensive understanding of the genetic basis of cancer. Additionally, expanding GWAS to include diverse populations will help identify genetic variants that contribute to cancer risk in different ethnic groups.
