People with Down Syndrome may be providing important clues as to how we can slow down cancer. Those born with Down Syndrome have a third chromosome 21 that causes some of their challenges, but that also seems to have some genes that may suppress cancer.
Scientists have long suspected that such genetic benefits might accrue from having an extra chromosome 21. A recent study found that people with Down syndrome are only about one-tenth as likely to get a solid-tumor cancer as are people without the syndrome.
