Wrinkled, saggy breasts? Turns out breast tissue ages faster than the rest of your body

Well, it's not great news, but at least we know we can blame the biological clock! You've hopefully spent years lathering up your chest with SPF in an effort to protect that precious cleavage, but it turns out wrinkles and sagging breasts happen a little too quickly because that tissue ages faster than the rest of your body.

Steve Horvath, professor and researcher at the University of California, Los Angeles, is among a group of experts who have identified a biological clock embedded in your body's genomes which is helping them understand how we age, and why. The clock focuses on methylation, a natural process that alters DNA, and charts how aging affects this process. In the study, researchers compare tissue's biological age to its chronological age.

Interestingly, while most tissue samples see an equal biological and chronological age, some did not. Among the few was women's breast tissue, which they found to age faster than the rest of our bodies. Healthy breast tissue is 2-3 years older than other parts of the body. If a woman has breast cancer, the healthy tissue near the tumor is an average of 12 years older. Horvath says this might explain why breast cancer is so prevalent among women, and why age affects our likelihood of getting cancer in the first place. Tumor tissue was found to be 36 years older than healthy tissue... yikes. The major benefit of this research -- aside from new understandings of our bodies -- is that they're now looking into how to use this information for "studying new therapeutic approaches to keeping us young," as well as increase our understanding of cancer. And hopefully how to battle it better. Exciting! (Daily Mail)
