Scientists find that chromosomal abnormalities are associated with aging and cancer

Two new studies have found that large structural abnormalities in chromosomes, some of which have been associated with increased risk of cancer, can be detected in a small fraction of people without a prior history of cancer. The studies found that these alterations in chromosomes appear to increase with age, particularly after the age of 50, and may be associated with an increased risk for cancer... The results of the studies were published online May 6, 2012, in Nature Genetics.
