These other mutations are rare and do not increase risk as much as BRCA1/2 mutations do. In the past, breast cancer genetic testing only checked for mutations in BRCA1/2 genes. Now, genetic testing can be done for several other gene mutations (in addition to BRCA1/2) that increase the risk of breast cancer.
Delavan is a city in Tazewell County, Illinois, United States. The population was 1,825 at the 2000 census. It is part of the Peoria, Illinois Metropolitan Statistical Area.
Origins[edit] Delavan sits in the middle of what was at one time an inland sea. During the last Ice Age, many glaciers, the last of which was known as the Michigan tongue, covered this area. The Michigan tongue descended down what is now known as Lake Michigan.
