In a study recently published in Nature (journal impact factor 36.1), researchers describe nine new genes that drive the development of breast cancer. This takes the tally of all genes associated with breast cancer development to 40.
The team - which includes Anita Langerød and Anne-Lise Børresen-Dale from the Department of Genetics at the Institute for Cancer Research - examined all the genes in the genomes of 100 cases of breast cancer. The mutated cancer-causing genes were different in different cancer samples, indicating that breast cancer is genetically very diverse. Understanding the consequences of this diversity will be important in progressing towards more rational treatment.
