Novel applications of next-generation sequencing in breast cancer research.

With the rapid development of medicine, the studies of genes have become increasingly concerned by more people and being the contend of a great of researches. The next generation sequencing with its own advantages has been widely used in gene research nowadays. It has almost replaced the traditional sequencing methods (such as Sanger sequencing method), and played an important role in a variety of complex disease researches, including breast cancer. The next generation sequencing technology has the advantages of high speed, high throughput and high accuracy. It has been widely used in various cancers (such as prostate cancer, lung cancer, pancreatic cancer, liver cancer, etc.), especially in breast cancer. Moreover, the use of the next generation sequencing technology to make DNA sequence analysis and risk prediction has made a great contribution to the research of breast cancer. We will focus on the application of whole genome sequencing, exon sequencing and targeted gene sequencing in breast cancer gene research.
