NASHVILLE — U.S. cancer researchers say they have identified an area on chromosome 6 that’s strongly linked with breast cancer susceptibility in Asian women. The Vanderbilt-Ingram Cancer Center investigators led by Dr. Wei Zheng said identification of the genetic “locus” might help guide efforts to find the specific genes linked with sporadic — or non-inherited — forms of the disease. Genetics plays an important role in the disease and some breast cancer susceptibility genes — such as BRCA1 and BRCA2 — have been identified, the scientists said. Mutations in those genes increase risk of inherited forms of breast cancers. “But the genetic factors identified so far explain only a small percent of all the cases in…
